ok any suggestions with differnt speakers/subs/ head unit?

Open to any and all suggestions for a complete stereo.

I left out the amp cuz they confuse the shit outa me with all this wattage/2 channel and 4 channel stuff. The only thing i know is that more wattage= bigger price tag.

Also when do you need to add another battery and other things like that?

I love alpine. Like alot so they are basically all i want to put in the car. But i am open to seeing other brands that are same quality.

I have a big budget but also want to have fun with this project i am planning on doing my own sub enclosure with my dad who does fiberglass work.

I want something that is going to hit verd hard as well as mantain very good audio quality.
I dont want something that is all compeition stuff but i want something that can hurt my ears if i turn it up loud enough.:)

Any help is greatly appreciated.

Going in my FD so you know what i have to work with room wise.

2 subs that big is gonna be WAY to powerful for your fd. your not gonna want 3000 watts 2 feet behing your head while driving it just wont be comfortable and youll hate it.
unless your a guy that likes to be completely deaf when you get out of your car and your brain feels like its gonna explode.

if you have a big budget get a JL w7 12 on a 1000 watt amp and and be done. an addad bonus witht his set up is that you wont have the added weight of 2 12's and a huge box .

Would 2 tens type R alpine be enough to get the effect i want.

I have this thing about semtirey and have to have 2 of everything to look nice.

Dont ask me why just been one of those things since i was little.

Would the 10's be to big?

1 ten does wonders for me. But i drive a FB.

Well i want the term "take your breath away" to be said when sitting in the car at the right volume.

Would 2 tens accomplish this at the right wattage? Also what amp would be good to push 2 tens?

What side door speakers are like way awesome, I love to listen to lota of very differnt types of music and

want a broad range so the side speakers are very important to accomplish that complete sound? Or is

there other ways to achieve this?

Well crap, just had a big reply typed up by my computer crashed ... lets start over.

First off, the problem with dual subs in a RX-7 is it really limits your placement and box size options. I say you're better off with a single sub, and optimizing it's box and placement. If you want to stick with Alpine, that's fine, the Type R are great subs. Specifically I'd go with a single 10 or 12 and put it in an Extended Bass Shelf enclosure near the back of the hatch area. You can use WinISD to model a good EBS enclosure.

For the front stage, 95% of what you hear will be coming from them so don't skimp. Taking the time to properly install a good component set up front makes all the difference in the World. Put lots of damping material on your doors, do fiberglass work to put the midbass driver in a completely sealed enclosure, and mount the tweeters up high on the doors and angled toward your head. Again Alpine makes some good components sets, some of the Type-X stuff can sound excellent. Definately don't use a co-axial if you have the budget to do it right.

And you won't need a separate battery for this setup. Just make sure what you do have is in good shape, alternator, wiring and chassis grounds, battery, etc. Use a pair of the Alpine Class-D ICEPower amps, they're much more efficient than typical class A/B amps, which means they won't draw as much current from your charging system. They're also smaller, run cooler, and sound excellent.

Thanks alot for the info!

The x set was something i was looking at and will most likly go with those.

I have only one concern and that is i want it to hit hard and i fear that one sub

with a good enclosure isnt going to give me that seriuos thump i want. I dont

think i will ever really turn it up that loud to get that big boom its just nice to know

its there. Do you think that i can get that effect from one sub?

I was able to hit 136db with a single 12" in the back of my FC ... in 1994! So yea, I have no doubt that as much as things have improved in the last decade that a single sub in an RX-7 can go a lot louder than you can handle.

So you think W200, Xset up front, 12 type R, and that amp Class-D ICEPower (more then one?)would put me where i want to be?

I would think so. I'd get two amps, a big Mono for the sub and a 2-channel for the front stage. Just cover all the details with the install like sound deadening, good wiring, proper install of your fronts, etc and it'll turn out good.

You have a "big" budget doesnt really help. I could reccomend a set of rainbow reference speakers that will do more then "take your breath way" but they cost $10,000. The type r is a great sub, but is an entry level sub and better can be had, for the price though it is a good sub.

I have the w200 in my car and love it, i use to be a huge alpine fan boy, had their type x speakers and subs. Didnt really like them, at all, magnet was a bit too big for the fronts anyways.

Give me a budget and ill give you an ideal set-up. One 10 or 12 is enough, i had two 12" diamond d6's and it was unbearable and completely pointless with such a small cabin.

DONT FORGET:
its 90% install 10% Equipment

I did some thinking last night and have alot of stuff laid out on what i want to do with my 7 and i think that it would be better to tighten this budget so i can afford the dreaded LS1. My initial budget was 2k buying brand new everything wires new battery the whole nine, But now i think it would be best to cut that in half and start there. So PureRx7 I would say my budget is around 1k, But with the budget cut that means i am willing to buy used stuff maybe ebay or a local listing so if i can find what i want used for under 1k i will be happy if not i am willing to work a few extra hours to get the budget up to 1.5 i suppose if i have to.

So what suggestions for a setup would you think would be good?

go with the jl like i suggested. the w7 12 can be had brand new for around $400 the amp can be had for around $400 as well. which will leave you around 200 for a box and wiring. with this setup you shouldnt have to get a new battery or upgrade the alternator.

Since you're now talking on a budget, get the Type R sub and go with Pioneer PRS components. The PRS set is probably the best price/performance component set out there right now, and a single Type R 12" with 500watts in a RX-7 can produce more output than you can stand. Also get on one of the mobile audio sites, like diymobileaudio.com and use the classifieds.

Thanks guys for the help so much. I hope there are alot of people who will be able to use this thread for ideas. Now as far as sound damping goes would it be a good idea? I want to do LS1 and its loud so i am thinking it wouldnt be a bad idea. Any suggestions?

For a single 12 setup, if you are wanting something really loud, I'd go with a DD sub or Audioque. They are the same thing basically and they will take TONS of power and sound good doing it. Very affordable too.

For sound dampening go to secondskinaudio.com and cruise the site. You will find what you need; no matter what it is.
