JL's have great SQ. RF's, not so much, kind of a decent mix though. Look at Elemental Designs, great SQ and decent cost. Also Image Dynamics makes a killer product. Lots out there, just got to dig a bit.

i wish i took pics of it before the car got jacked.

if you wanna see other pix of my other project in my friends civic stock alt. running a rockford t4000bd 300amp draw, t800.4 140amp draw using 2 2400 kinnetic bats, never killed the alt.

like i posted earlier you gotta drain the bats before any damage can happen. even then the amp protect should kick on.

dohckiller808

if the amp is rated for 2 ohm. it will be most efficiant at 2 ohm. i have my truck wired to 1 ohm but a small amp so it doesnt drain that hard. it all depends on the amp and how low of voltage it will play.

9 times out of 10 if your running your stereo that hard the battery and amps give up before the alt.

most alts. get killed from people washing their engine bay and getting it wet.

Seems to me that 500 amps from the stock alt is, in fact, bullshit. There is a reason alts are rated to say, 100 amps, that reason being they can't produce more (at least not much more) than that rating. Thus the reason alts are frequently rewound, so they have the ability to output more.

Now I might believe you got 500 amps out of the batteries, but if you are really trying to tell me that 500 amps came cranking out of a god damn civic alternator, that's more bullshit than i can handle.

dohckiller808

i didnt say my alt kicks out 500amps jack ***. i said i havent blown my alt while sucking 500amps from my stereo.

can you comprehend that?

do you need me to break down how this concept works?

I've got news for you sunshine....if you pulled even half that much current through the 60A alternator that comes on a Civic it would probably go up in flames and you're not going to convince me otherwise. I think you're full of **** as a Christmas goose. Most of the competition systems I have been involved with have high output alternators and multiple batteries, some have even had multiple alternators. Wnen I showed my friend who runs a auto electrical business your claim all he could do was laugh and say "I want some of what he's smoking".

Don't know about you other guys, but I'm done with this fool. He obviously doesn't have a clue what he's talking about.

dohckiller808

ok. so in your world all these cars with stereos shouldnt be running then?

my 7 is running off the stock alt one red top with 180amp draw just from my amps. your saying it shouldnt be running?

scrims: my civic stereo draws over 500amps going to a stock alt. BUT i have 2 yellow tops

look. we all know upgrading the alt is a good thing yes?
im saying- by putting in a stereo it will not kill a stock one.

all the alt. is doing is charging the battery.

the more batterys i have the longer it takes to charge and vice versa, the longer it takes my amps to drain them.

all a stronger alt is doing is charging my bat faster.

slamming your stereo will kill the battery from all the discharging and recharging before the alt blows out from a stereo.

now if we were talking about pulling a 2000amp draw at one crack with out electrical upgrades we would see some cool crap smoking up.

does this make sence to anyone or are all the cars ive built in flames as we speak?

I understand what you are trying to explain, but many of the fools on this forum will argue for the sake of argument. yes with two optimas you can pull 500 amps for brief periods of time. your alternator will only make its rated amount, however the batteries and and stiffening caps you might have will enable you to dump a lot more for short periods prior to draining them.

for everybody else...take a ******* prozac or something

a battery has how many cold craking amps? short that mother ****** and see if you don't get all of them. you will until trust me its spectacular .

an optima is generally rated at either 750, or 850 CCA which means that it alone without an alternator hooked up can put out up to the listed amount of amps for a short period of time until it is drained down. The alternator will just be overworked if you run it for extended periods of time until either the batteries go dead, the amp fries from trying to draw too many amperes due to the lowered current (in unregulated setups) or the alternator finally craps trying to recharge the bateries.

To the other knuckleheaded internet gangsta wana be

running the amp at 2 ohms was not the cause of the alternators failure. it was the fact that you were drawing too much current for too long. i can do the same with a couple of large amps running at 4 ohms vice 2 it is simply dependant upon how much current you are demanding from the battery/alternator setup not because it was at 2 ohms. It was becasue your amp at two ohms drew too much current from the system.

what happens when you run a 2 ohm front speaker setup? nothing because you are not drawing enough amperes to strain the alternator. so STFU & take a prozac

wow, kenn in a bad mood indeed.

I do now understand what dohckiller is trying to say, though the idea gets muddled through talking **** and poor wording.

You should be telling us that you are pulling 500amps from your batteries, or even that your amps draw that much. But to say you're getting 500amps from your alt is very very misleading.

Scrims,

sorry I have to deal with idots all day long here on the base, and I am half way into a bottle of wild turkey... my apologies, I was being a bit of an ***.

and truly DOHC killer did not word it well.

for all, just try and read into the others comments and try to understand what they mean to say.

You all should try explaining something to someone who's primary language is not english and is an asshat to boot, thats what I deal with on a daily basis so I have learned to read into a persons comments alittle more to help me understand.

i have 2 12inch JL older W6's where my back seats used to be. i dont know what your looking for in your subs but mine are pretty good with all around music i listen to pretty much everything. i have a 1100 watt kenwood amp powering both of them. it might be to much for what your looking for but, i have a really loud exhaust and i would like to hear what im listen while im driving so i need loud music. i tried uploading a picture i dont know if it worked tho..

Scrims

iTrader: (2)

Yeah, probably a bit more than what i'm looking for, hehe.
Though what is the point of mounting them that way? In my experience I've only seen subs mounted with the cone facing outwards.... What's the advantage?

dblboinger

iTrader: (3)

Yeah and do this too many times and your alternator WILL fry.

dblboinger

iTrader: (3)

True, but in an electrical circuit with multiple sources the load wioll be distributed evenly if possible. That means the alternaotr will be trying to output 250A, which it can't do. Again, do this too many times and your alternator is toast.

dblboinger

Bingo! And if it weren't at 2 ohms it wouldn't have drawn as much current. Any way you ******* slice it 4 ohms draws less current than 2 ohms and is therefore safer. Safer on your equipment, safer on your battery and safer on your alternator.

Personally I never run 2 ohms in the front, there's no need. My amp is plenty powerful to give me the highs without it, especially since the Focals are pretty bright anyway. 2 ohms on a sub, or even 1 ohm, is in order to get more power so it will be louder. Lower impedance = more current = more power=louder. There's no other reason to do it. The sound quality doesn't improve, it just gets louder. The reason it doesn't cause problems in the front is because the front amp is usually about 1/4 - 1/3 the power of the sub amp, anything more is simply unnecessary for a properly balanced system.


I AM done with this subject asshat. Reply if you want but it'll be on deaf ears for all I'm concerned.

i dont know if there is a advantage or disadvantage. i just didnt feel like cutting the hole for the subs anybigger than it was. i do know they still sound good. i have them running in parrallel.

the only difference is that you are saving the displacement square footage of the sub in the box. So air space is exact with LxWxH. A sub that size would take up a lot thus you would have to make the box larger to compensate. Not sure if changing the phase of the sub is also recommended like that. Ive never done it, but know a lot of people that do and it sounds the same as subs mounted inside. I know most my stereos have phase switching options for subwoofer output.

Sweet, thanks for the info. Think I have enough to get started shopping and buying. I might make a project thread when I make my fiberglass/mdf boxes for the corner(s) of my hatch.

dohckiller808

sound dosnt come out as clean. we usually run the sub backwards if we cant get enough space behind the magnet to have it in the regular way.

like we did here. no way the subs could be faced the other way.

kenn_chan

The question that was raised was if running "an amp" at 2 ohms would fry the alt.

The answer was/is NO if you are drawing too much current it will, but htis is no different than running a large amp at high impedance in that it could also fry the alt. by drawing too much current. 2 Ohms, 4 ohms, 1 ohm makes no differeance to the alt. its only concern is the amount of current. bye clown.

kenn

you were

as I said if I use a large enough amp sub combo at 4 ohms it would do the same thing.

dohckiller808

i duno if this help but a single jl 10w6v2 with around 500-800rms will do the trick. with the space u got in the 7 i dun think 2-3 sub is a good ideal. unless ur willing to get it custom made
