My roommate is going to buy an 01 Impala this week for around 3500 and wants me to put a system in it. I currently drive a Trailblazer with the following equipment

Clarion NX501
Eclipse SC6500
Massive Audio NX2
(2) Fi BTL N2 12's
Crescendo BC5500
4 runs of Knu KCA 1/0
250a alt
(2) XS D3100's


So I know what I'm doing when it comes to audio. Now enough about my system, here's the equipment list for his, it's a low budget build.

JVC KD-S37
Pioneer Premier Comps
Knu 4 awg
Audiopipe 1500d
Custom TC Sounds TC-7 12

and the plan is to build a false wall in the trunk so when you open it you don't see any subs or anything, then fold down the seats and have the sub and port loading off the false wall. What are your guys' thoughts on this?

It's an interesting idea and I like it. FWIW, my 10" bass tube was louder when the port was facing away from the cab. Not sure how a false wall will effect the bass.

the false wall will act like the trunk lid, it'll just be moved up the vehicle a foot or two. that's what's called loading is when you point the sub and/or port at some sort of wall and use that to reflect sound off of.

I have a false wall. I also point the subs into the car. I get a tighter bass (3 10's) that way. Keeps the sound in the car. I would, and still might change the sub's. I have 8's where the 6x9's go and 4.5 mid's and tweets where the factory amp goes. I would change to a single 12 and six 8's.
My false wall is 1/2 inch ply with fiberglass resin on both sides. Trunk doesn't rattle. Its gapped about on inch away from the box for extra wires to go up and through and then filled with poly fill.

this will be ported and the false wall will most likely be 3/4 inch MDF. the box will be 2.75 cubes tuned to 31hz. This TC likes big, low tuned boxes.

If its ported I would fire it up towards the factory amp hole. Will keep from hearing the woosh of air as its hits solid surfaces. And soak the mdf in resin to help stiffin it up.

I've never heard a "woosh" of air from any of my set ups, they've all had port back, some even sub and port back.

I'll do a build log up on here when we start. He should be picking up the car Thursday, then we gotta do speakers and run wire. He gets paid Friday then we'll order his integration harness and dash kit. The false wall will be the last thing we do because neither of us has much time with work and other obligations.
