Grand Prix Gtx...i Want To Block Off My Trunk...help!

[99GPGTX]

i would really like to block off my trunk...i want to have woofer/woofers firing forward and not have any air get released into the truck... how do i go about doing this? right now i have a 12" BTL on 3k but could change if i want to. only thing i hate is that i cant fold my back seat down.

but i have no idea how ill go about doing this

im also going to build a new amp rack

came upp with this a while ago... not sure if it will help

the opening to my truck is really small so...

im nowhere near a pro but i would start buy building in the trunk to the max specs possible and then use expanding to seal it off competely...look like you can get the 12 reconed to a 15 and run 2 of them then put your batteries in your spare tire well and mont the amps on the back of the box..but thats just a thought..actually thats what i would have done but instead im walling my car..

fire the sub/port up through the rear deck, seal everything else off from there.

im just not sure how im supposed to go about doing this...

and i want to do this without distroying my car...i want to be able to take it all out...if i need to and not have my trunk look like a peice. i want it to be done right and look niiiice

In order to seal it off from the trunk you'll need to use expanding spray foam. That's kind of permanent and is very hard to get off. I have a couple of pics of trunk walls that were in my car. One was with a Fi btl 12 and the other was with 2 Dc level 4 10's. The pic of the Fi sub doesn't look like it's sealed off, but the black on each side of the enclosure is spray foamed and then bondoed over and painted black. I went to the DC's after that and just carpeted over where it was painted black.

This one wasn't a trunk wall, but it filled the entire opening of where the back seat folded down from the trunk.

The loudest of all of them on the TL was the single Fi Btl 12. It did a 145.7 off of a single american bass 150.1

Sorry, I wasn't trying to jack your thread either. I just figured I'd give you a few examples of what my past trunk walls looked like so you could get an idea of what you wanted to do. Personally I'd get another Fi 12 and do two of them in your Grand Prix. One will be loud, but two would obviously be louder. You could even upgrade to 15's, but I think you have the right amount of space to do 12's and be very happy. You could even just use the amp you have now and it'll still be louder than just running a single 12. Good luck with the build.

the bigg problem with running two is the box..my opening to the truck of my car is soo small..the box i have in now barely fit as is

and i would need another amp., another hc2400, and prolly another run of 1/0 then install and whatever else....ill prolly just stick with the BTL or a DC lvl5

i just dont want to do this and have it come out look shady

you DONT need expanding foam for EVERY CAR. just build it like gp's buick. he didnt use any. its sealed off.
