sound system setup
 
i am trying to get the show car look for my setup and currently im thinking about using a full audiobahn system with the amps and the subs that have the flame designs on them, but the brand doesnt matter much to me, what i am worried about right now is the placement of the speakers and amps
attached is a diagram of what i am thinking about right now. anyone have any critisim, or any tips?

also does anyone have any recommendations on a good brand that has good quality, but can also get a big boom when you want it?

spot_skater 08-15-04 09:01 PM

looks pretty good, just make sure you keep the tweeters at almost head level, and the woofers down low

and if you want to get crafty you can make a custom enclosure in the passenger seat area, by the floorboad of the passenger's left foot, put an 8" or 6" mini-sub down there, too

porsche's do that, and sound good

Molotovman 08-15-04 09:58 PM

Well, Just remember you're gonna need a crossover or two depending on how big you go.

Also, just a reminder. All of the midrange speakers aren't going to make a difference. say you have one speaker, and you get one pushing the same power, it's gonna add 3 dB to your total sound. I'd say 4 mids, 4 tweeters, and 2 subs.

You already have separates up front (tweeter and woofer), what are the speakers to the side of the driver's and passenger's legs going to be (coaxials?), and moreover, where do you plan on mounting them? Also, how do you plan on fitting two 12" subs w/ 4 amps in the trunk, and, let's assume you did so somehow, what's the point of having coaxials behind the driver's and passenger's heads?

Your diagram is overly ambitious and ridiculous at the same time.

a lil more critisism than i was thinking :D
i guess you are right though. it is a little over the top.

as for the rear, i was planning on making a custom bed that was high enough to embed the subs into and the amps will only be like 2" in thickness, so i was thinking if i embedded them at an angle so that part of it is below the top of the bed then it would be ok.

as for the tweeters i was planning on having them embedded right next to or below the side mirror adjuster and have another on the door on the other side (for the higher frequency). the woofer behind the drivers head would be there so that if you tilted the seat back into a reclined position (not reclined for driving, reclined for like resting) then it would be by your head, i may acutally use tweeters for that. the woofers by the drivers leg and the passengers leg would just be extra, just for show.
As for the four amps in the back:
the two big ones would be powering the subs and the two little ones would be powering the woofers and the tweeters. Or i may use one or two for the subs, one of the small amps for the woofers, and the other for the tweeters.

i am going for that show look, so im not planning on having everything have a purpose. but i am still thinking about the speakers behind the drivers head, i might take those out. the woofers embedded into the door panel will be towards the front, but down low.

the show look still usually works and you don't need all those speakers for a good sounding system. a really nice set of components like say the infinity reference series would sound really good behind an amp and then say 2 12's made by JL is probably all you need all being pushed by an appropriate amp of course.

What's the "bed" going to be made out of, and will it have proper internal volume for the subs? Do you even know how big a 12" sub is depth-wise? I'm still curious to know on how you plan to fit two in the trunk.

That's a pointless idea. :rolleyes: Instead of either woofers or tweeters, why not coaxials that have BOTH a woofer and a tweeter???


the woofers by the drivers leg and the passengers leg would just be extra, just for show.
So you'll just have tweeters for your front stage??? :confused:

What amps, and how much power?

:gotrice:

You *do* know that the mounting depth in non-BOSE FDs is about 2.5", right? Most component woofers won't even fit.

I'm calling BS on your thread. You have no idea what you're doing, now do you?

:bsmeter:

dblboinger 08-16-04 12:45 AM

I would recommend ditching the driver right and passenger left speakers and install a single center channel in the dash somewhere. The reason I say this is you are going to get all kinds of weird peaks and dips in frequency response due to physical alignments of those two drivers in particular. If you don't use the A/C you could put the center channel behind the A/C vents. Otherwise a good reputable shop should be able to install a center in the top of the stock dash, but it will cost you.

Also, if you mount the speakers behind the driver/passengers head they will be facing each other but worse than that, the driver/passenger will be severely off-axis from the speaker. That will definitely limit the sound that will reach your ears, especially in the high frequency band. It would be better to mount the rear-fill speakers farther back and "aim" them towards the passenger compartment.

Placement of mid and high frequency drivers is MUCH more important than the subs. Put the subs where-ever you want and point them wherever you want. Bass sound is totally non-directional so these things don't matter, but the higher the frequency the more directional the sound therefore placement becomes increasingly important. The big problem with door speakers is that the one on the drivers side is much closer than the one on the passenger side (if you're the driver). This being the case the sound from the close speaker and the sound from the farther speaker will arrive at your ear at different times and in varying phase relationships. The result is you will have frequencies that you can't hear as well and you will lose some spatial quality. The remedy is to put the mid and high frequency drivers farther away from your ear, thereby minimizing the effects of this anomally. That is why you see mids/tweeters mounted in the kick-panel area. If you do this though be sure and "aim" these drivers into the passenger compartment as well or you legs will get a really good reproduction of the music, but not much else.

As for brands....there are 100's to choose from. I'm partial to JL or Kicker for subs....MB Quart, Boston Acoustics and Polks for seperate speakers, Alpine for the head unit and Phoenix Gold or Rockford Fosgate for serious power amps.

Let me tell you..at one time I had a 1st gen with 8, yes eight, 12" Becker subs in the cargo area. Four pointed up at the rear and four pointed forward just behind the seats (I tore out the storage compartments to make room). I powered it with a single Orion GX2350 (700 watts +3dB headroom which comes to about 1400 watts on the peaks) It got real hard to breathe at about 1/3 volume...and it was hell on windows. My mids/highs were from 2 pairs of Boston Acoustics 6.5" seperates powered by a Nakamichi 100 watt x 4 channel amp. It took me 3 tries to get all those subs in there. Not very practical, but it was great for showing off on a Friday night!

satoacs 08-16-04 12:47 AM

OMG...SpeedKing are you trying to be a dick or am i reading your messages wrong?!?! im not a retard you dont have to talk to me like i am one.

the bed will be made up of wood, with the appropriate height (about 8"), and the wood will be covered with some fabric for dampening purposes. It will also have a lowered "box" for the amps to sit in. With the amps angled right i will only need this bx for the amps to be about a 2-3" deep.


That's a pointless idea. Instead of either woofers or tweeters, why not coaxials that have BOTH a woofer and a tweeter???
im correcting myself...im not going to use a woofer im going to use a tweeter...you wouldnt want to have bass or anything loud blasting into your ear while your relaxed, so i am going to use a tweeter for clearer sound.


the woofers by the drivers leg and the passengers leg would just be extra, just for show.

So you'll just have tweeters for your front stage???
no...the woofers on the right side of the drivers leg and the left side of the passengers leg, i may take those out, but now that i think about it i may leave them in because i will have another one on the other side in the door.


What amps, and how much power?
i am thinking about using some audiobahn amps, the two big ones totaling 1000(peak) and the two small ones im not sure about yet.

now like i said im trying to go for that show look, not rice.rice would be a whole bunch of crap that no one needs...only stuff that show-offs would care about. im not doing that, im only looking for a nice sounding system that looks good.


dblboinger: i understand what your saying and your right abuot it, but i have put all of that into concideration and have forgotten to mention it here. the speakers behind the driver and passengers head i am planning on aiming forward. the speakers by the legs i am planning on aiming towards the floor some and towards the seat some so it goes underneith the drivers feet instead of right into their pants.
i am not going to pack as much power as you said you had, but i will have some and i want it to "BOOM" at certain times. i am thinking about audiobahn because i heard that it is a "very loud company", but i think i will go with their amps and subs for the loud booms, and i might go with a quality company like infiinity or something

dblboinger 08-16-04 12:51 AM

And a word to speedking....there's only 2.5" in the doors unless you're willing to do a bit of modification to the panels. I did away with that worthless little map-pocket and fabricated a panel that gave me well over 7" of mounting depth and looked better to boot! Imagination is the only limiting factor when it comes to customizing. If there's a will, there's a way!

i couldn't have said it better, that pocket idea is what i was thinking about. thats why i keep saying "embedded" because i am going to take out almost everything that you don't need, like the pockets, and just make it extra room for embedding speakers or whatever i want the room for

and for ppl who pick at everything you say and need every single detail....i have revised my diagram and attached.

dblboinger 08-16-04 01:08 AM

FYI...I used thin pieces of 1/4" press board tack-glued together to shape the panel then when I got it the way I wanted it I had a friend lay fiberglass over the top. When done we pulled the pressborad pieces out and re-inforced the inside with more fiberglass, probably 5'8-3/4" thick when we were done. We made a lip around the edge that was to mate to the door panel and using tinnerman clips screwed it to the door panel, then covered the whole thing with black speaker-cloth. We used speaker cloth because it stretches to fit the contours of the panel. Another option would be to sand/paint the fiberglass, as you see in a lot of installs nowadays.

dblboinger 08-16-04 01:12 AM

Oh yeah...and I also moved my electric window controls to the new "armrest" too. It worked out great.

send me a message, im curious about this. do you have any pictures? i may want to steal your idea :D

dblboinger 08-16-04 01:20 AM

Unfortunately the ex kept/destroyed all photos having anything to do with me so all I have is the memory of it. Thinking of doing something similar in my new project, an '83 GSL, except I think I'll just do 2 12's this time...and a lot less power.

I've read most of the posts and threads you've started on this forum, and frankly, you've asked questions totally devoid of common sense and lack any serious thought behind them.

Here's some "gems" of yours:

https://www.rx7club.com/engine-management-forum-37/purchase-order-338043/

You can clue yourself in to the answers to what you ask if you bothered to use the search function.

Personally, I don't believe you own a "'94 RX7" and you're nothing more than a dreamer.


the bed will be made up of wood, with the appropriate height (about 8"), and the wood will be covered with some fabric for dampening purposes. It will also have a lowered "box" for the amps to sit in. With the amps angled right i will only need this bx for the amps to be about a 2-3" deep.
For the second time, "Do you even know how big a 12" sub is depth-wise?" You're going to need an enclosure that's at least 9"-9.5" tall.

And, "fabric for dampening purposes"? No such thing. :rolleyes:


im correcting myself...im not going to use a woofer im going to use a tweeter...you wouldnt want to have bass or anything loud blasting into your ear while your relaxed, so i am going to use a tweeter for clearer sound.
Why would you have tweeters as part of your rear stage? You know you only get high frequencies through your tweeters, right?


no...the woofers on the right side of the drivers leg and the left side of the passengers leg, i may take those out, but now that i think about it i may leave them in because i will have another one on the other side in the door.
How many woofers are you going to have in the front? Four? Why?


i am thinking about using some audiobahn amps, the two big ones totaling 1000(peak) and the two small ones im not sure about yet.
Yeah, sure you are.


now like i said im trying to go for that show look, not rice.rice would be a whole bunch of crap that no one needs...
HELLO!


im not doing that, im only looking for a nice sounding system that looks good.
Isn't the point of putting together a stereo system in your car is for it to sound good? You're not supposed to see it.


dblboinger: i understand what your saying and your right abuot it, but i have put all of that into concideration and have forgotten to mention it here. the speakers behind the driver and passengers head i am planning on aiming forward. the speakers by the legs i am planning on aiming towards the floor some and towards the seat some so it goes underneith the drivers feet instead of right into their pants.
Why would you want sound to go to your ass and underneath your feet? Correct me if I'm wrong, but aren't your ears are on the sides of your head?


i am not going to pack as much power as you said you had, but i will have some and i want it to "BOOM" at certain times. i am thinking about audiobahn because i heard that it is a "very loud company", but i think i will go with their amps and subs for the loud booms, and i might go with a quality company like infiinity or something
With two 12" subs, you will "BOOM" ALL the time. BTW, what about farad caps, and a secondary battery, or an upgraded alternator? You'll need those too for those four amps of yours, four woofers in the front, and four tweeters, two in the back, and two in the front. :rlaugh:

satoacs: You're a funny guy. I can't wait to read your next post! :D

spot_skater 08-16-04 11:02 AM

the woofers or midrange or whatever aimed at the driver's legs doesn't really serve a purpose

have you ever seen the OEM front speaker mounts in an FC (specifically s4)
they're basically pointing down at the passenger/driver's knees, it's pretty shitty

i'm going to have to a gree with speedking about the mounting depth of a 12" sub, those things are BIG, probably around 6-8," if not more, you might want to re-think using 12's, remember the car is very small...

if i were you i'd make a custom fiberglass mold to hold the subs in the trunk, it can form more freely than wood, and fiberglass is just cooler =x

and you WILL need two crossovers if you're going to power the front speakers in the doors with an amp, go for a FOCAL's utopia line, they're really good...but expensive...will crossover's fit in the doors? FOCAL's crossover's are rather large, as compared to say, DLS

don't take this as an attack, either, just my opinion/advice or whatever

also, you have storage bins, why not take them out and make a new enclosure that may be a little larger to hold the amps? then you can do what another member (SORRY I FORGOT WHO DID IT!!) here did, he used computer fans to cool his amps which he keeps in his storage bins, and it looked real cool...do a search

best of luck, i'm curious to see what you end up doing...

Try this on for size.

http://memimage.cardomain.com/member...9_157_full.jpg
So in total Ihave 1 12's and a 15".
Check out my page for more info. All out of sight, you don't have to show it off. Let them hear you.

John

P.S. I agree with speedking, on all points.

satoacs 08-16-04 02:20 PM

you guys are just picking at everything i say. the point of a show car is to go to shows and show-off all of your stuff....thats what im doing....

and the thing about the speakers on the sides of the drivers leg...thats not what i meant, the sound isnt gonna go straight at their legs, its going to go around it and back up.


Isn't the point of putting together a stereo system in your car is for it to sound good? You're not supposed to see it.
thats true for any car, except if your making a show car!!


With two 12" subs, you will "BOOM" ALL the time. BTW, what about farad caps, and a secondary battery, or an upgraded alternator? You'll need those too for those four amps of yours, four woofers in the front, and four tweeters, two in the back, and two in the front.
of course i have all of that taken into consideration. this was a post about the sound system's positioning only, not about the extra things that i will need to make it work.

this was just a simple post, i only wanted to know if it would work or not.

Molotovman 08-16-04 03:11 PM

Looks like you need to do some more reasearch, or have your system professionally done, you really don't seem to know what you're talking about.

im not arguing with that, i am going to have it professionally done, but they are gonna ask me where i want everything put in. thats why i started this whole thing.
i have also been told that they will have to rip out the whole rear and put a new "bed" in, made of wood and fabric, becuase of the issues with space.

blue 88 08-16-04 04:44 PM

man, go look at any real show car. it doesn't matter what they look like their stereo's all work and the speakers are all connected and play very strongly. do some searching around and look at other peoples systems and try to get some ideas from them. i am not a dick, and i don't care what you want to call me. i am putting this in as nice a term as possible, think before you speak.

satoacs 08-16-04 09:02 PM

what am i supposed to be thinking about, this whole thread is about thinking about what kind of system i wanted to put in and if my diagram would work.

knotsonice 08-17-04 05:26 AM

Sorry man that that many speakers in an FD ur crazy. Your limited on space for 1. I got a set of pioneer 5 1/4 w tweets and 5X7's, in the hatch 2 10" subs. I spent a lot more money in 95 in my 88 rx and this system sounds a hell of a lot better. You don't need to go all out dude really.....

Carl

satoacs 08-17-04 10:54 AM

i know its gonna be tight, but i think i can make it fit, otherwise im gonna have to re-think this and either hide the amps or get smaller subs
