Need help designing a system

Welcome to the forums chipper

 

If it were me I would definitely plan on building a a box and porting it through the rear seat armrest or rear deck. Make sure whoever is doing the custom fab work knows their stuff and are good craftsmen. Do yourself a favor and buy some ols school orions off ebay and you wont have to wonder if you could have done better in the amp department. I would try to get a 450 for your surrounds and maybe a 250 or something for subs. You can pick up both amps for around $800 for really nice ones and they will out perform anything you can buy at your local stereo shop.
I am pleased with my JL Audio VR surrounds. I think for most people they are sufficient. Im pretty picky and I have no plans of replacing them.
Audio control makes a 3.1 that is a preamp/eq and I would consider it a necessity for any system. I have two of them. After I installed my first one I had to get another for my other car.
I just picked up an Eclipse CD7000 and love it.
I stick with JL Audio subs myself but that is because they always sould great for me. I cant stand buying/testing/hating/building boxes/returning/taking losses/wasting time trying to find stuff that Im not sure about. The sales people will sell you the product they can make the most money on and hope that you dont have high expectations.
So, I can say for sure that you will be very satisfied if you use some of the following:
Eclipse CD7000- $600
Orion Amps- $800
Audio Control 3.1- $280
JL Audio Surrounds- $Cant remember?
JL 12W6V2- $700
JL Audio Cables- $100
Custom box- $500
Total= $2980 Plus Installation. Pretty close.

 

whatever amps you buy, they aint gonna kick ass like Old School Orions. Dont waste your time. You'll thank me later.

 

Do you have room for a bandpass box for them 12's?

 

Good ol Orion, aint none better, period..............

Hey, does that beemer have the ski hole in the back seat????? I have done a few systems in those hitler cars (haha!!! ) that entailed the use of a single reflex bandpass using a single 10 inch sub. Sound quality was excellent due to the lack of reflective surfaces that the sub bass didnt have to reflect off of.........The same scenario could be incorporated using 2 12 inchers in a single reflex if you were willing to give up some trunk area........the sound is very tight, smooth low frequency extension, without exaggerated bass notes....Not ideal for "BOOM BOOM" systems, but why advertise.......

The highs you are reffering too should do fine, although there are plenty of others out there........Listen if you can to what you might be interested in, dont let someone tell you what sounds good, you let your ears tell you what sounds good.......

 

Sorry for gettign slightly off topic, please move this if it is appropriate. I remember it was 1999 I had saved up a grip of cash and took a trip to Wichita. I was crusing around town and went into a stereo shop and noticed this large red amp on the wall, so I bought one and had them hook it up. They kept trying to sell me this amp they had behind the counter. I can not find any info on it anywhwhere it was made by Orion and it was called a concert or concept or something. Said it had like a dozen channels and cost like 2500. I bet Viking can shed some light and it. Anyways 2 thumbs up for O/S Orion.

 

The bandpass box with a good sub problaby a better choice for listening rock, if it has a arm rest do it like Viking said.. bring the port thru there or have a good installer cut a hole thru the rear deck and have a custom grille made.

 

Your box would be pushed right up to your seats.
