back seat sub transformation

aite this is gonna be hard to understand but try and stay with me. haha alrite i am goin to remove my two back seats and try and flush mount a wooden frame and board. i am then goin to order honda carpet and cover the whole thing. i will be mounting either two 12's, two 10's, or one 12. and a pair of 6x9's. if u followed that i am askin if there are any placed that anyone knows of that would give me some advice on how to do this best. also if anyone has ever seen this done and how it looks. thanks

Never seen it done with straight wood and carpet. I've done it on cars and trucks by using wood to make a mold for fiberglass, making it all smoother looking.

what kind of car is this going in. And I don't think you want 6x9's in the back. It will throw off your sound imaging completely, and if you don't have back seats you don't have passengers to complain about not being able to hear it. Unless you have your heart set on it, I would toss the 6x9's idea because it will sound pretty bad.

I have also never seen it done with just wood but if done right it could look and sound fine. don't forget, you can't just put subs on a peice of wood, you have to have some sort of box or chamber behind it or you will get bad cancellation and again ruin your sound quality.

i have only subs and 6.5s in front and i can hear it all jsut find

You either have to put the subs in a box, or get free-air subs.

i have a CRX and did the same idea u have, i put two 12's in a piece of mdf the length and width of the regular back seat, and built the sub box around it. it worked out fine and sounded decent, but now i am going to make something out of fiberglass so it looks purty.
