A buddies car.

Infinite baffle off the rear deck with a FI IB3 12".

I really like the trunk of this car. HUGE. Stock 10-11" hole in the rear deck. Large flat area behind the rear seat to seal up the trunk.

pics = 1000s of words, so i'll shut up:

rear deck:


behind the seats:


7/16" thick weather seal on bottom of plywood:


Bolted, not going anywhere:

he's making the rear hole into a baffle. using the wood to keep air from coming into the trunk through the back of the seat and ONLY into the baffle (where the old oem sub was) and my ? now is isnt the back seat gonna be VERY uncomfortable now?

back seat comfort will be the same since nothing is going to poke through the seat

I had this setup in my previous car with the subwoofer mounted onto the wooden baffle because my trunk lid wasn't the best location for a 40lbs sub

The wood behind the seat is to help seal off the trunk from the cabin. In an infinite baffle config, you want to separate, the front and the rear waves the best you can, so they do not meet and cancel each other out.



I've browsed the IB setups here before I did this install, and I did see anybody sealing off the trunk to the best of their ability. I just saw a baffle bolted to the rear deck and a sub mounted to it.. and that's it.

More pictures are supposed to be posted, but they were waiting for the mods' approval, but they seem to never get approved. I'lll try to post more soon.

shown in the very first picture, i used some deadening to cover the small holes on the rear deck. I've also used some expanding foam, great stuff, to help with the sealing of the trunk.

The only thing about I didn't like about the rear deck, is the center seat belt assy is right next to the subwoofer location, which makes it almost impossible to seal off the trunk. Also the seat belt assy does a good bit of rattling.

I was going to say you guys should carpet that, but it appears the bolts are too long. I’d take a grinder, saw off the excess threads and carpet it. It won’t be perfect but it will look loads better than that…unless the stock carpet will cover that, and if that’s the case, who cares.

just thought you would lose something not cause it would poke through but because it doesnt have any give now if you know what i mean

oh and the rear seat-belt i cut that out and welded it up. im just gonna reposition the seat-belt bolt
you didn't use enough sound deadening... see below lol and im not done

James Bang

wow sakataj, that's surely is a lot of deadening, though you probably didn't need half of that. The best spots to put deadener is on larger flatter areas. Strong curvy areas don't need it. Looks like you did a good job though. What's your plans for the trunk?

Great info as well.


Here's the rest of the trunk install. It was just something simple. a two day job. Wiring can cleaned up a little

Trunk space galore:

Man, after looking at this thread, I need to redo my trunk. Just finally hooked up my beloved Directed 1100D I bought months ago. Need to get rid of my sonotube box for something a bit bigger.
