Maybe you have to cut hole in rear deck and the have a box built so that it ports all the sound to the cabin. I did that once on a design built by a stereo shop in town and the thing didn't have any bass in the trunk just in the cabin.

I concur with Easter. Have done many setups in Impalas and Caprices at my last job and the only way to get a good bit of sound into the cabin is to do a ported rear deck. I have done it multiple ways with large square small slot and variations in between. We did a bandpass with front sealed facing outward and the ported deck running thru the rear deck. I have also done it to where you just shave the insulation off of the rear deck carpet to where the port is firing at the uninsulated area so as to leave a stock looking interior. The only downfall is that it flaps a little while playing. I wish I had some pics but unfortunately I do not. But as far as porting thru the rear deck, get someone to run your specs thru like bassbox etc... and tune it correctly to take into consideration the port externally from the box. Also a helpful hint is to build the port with the extension from the box and the actual visible piece for the rear deck in two pieces. A lot easier to install.

Yo man, I had a ported box in the trunk, just thrown in there and I could clearly hear the bass was muffled so we cut a hole in the rear deck, like a 4"x8" hole and it made a hell of a difference....

Yeah, I have my subs in the quarter panels and a 10"x15" hole cut in my deck and the bass travels through really well. It'll shake the fillings out of your teeth.

So,I do need to cut a hole in the rear deck? I planned on putting a sealed box.I also thought of going with a free air type setup,mounting the sub or subs like the 6x9's are.Just trying to get the most effective design.

Depending on what you want. If you are porting it thru the rear deck then you need to determine style of port and build the box to work with that, but if you are just "venting" the trunk into the cabin get you a saw and get to whackin how you want it, then build a trim panel to clean it up. It's all in how crazy you want to get with it.

My subs are in a sealed enclosure. The way I cut my deck is get in the trunk and measure to get centered between the 6x9 openings. Then determine how far to cut behind the rear seat. Then draw a pattern on the metal with a marker. Cut the metal with a good air saw. Trace the opening onto the cardboard and you can cut that with a razor knife. Then build the cosmetic piece the way you want.

Make sure that you relocate the box that is attached to your rear deck so you don't cut any wires.

I have a sealed box with the deck vented like they're talking about... never heard it without it cut but it sounds good. Plenty of bass inside... even with juss the one sub.

nothin' special but pics always help...
I'll prolly re-wrap it whenever I decide what color interior I wanna go with. hth.

There is a few setups you should definitely check.... E-Dogg, Pimpala, Thump and mine are ones that I know are ported in the rear deck


I get NO trunk rattle whatsoever. When I'm bumpin', the bass is clean inside and out. I can roll up in a parking lot, pop the doors and it sounds awesome.


But I've got a bandpass set up. Its not as efficient for bass making as a ported box but it sounds pretty damn good as is....


Mine is a box firing into a chamber that fires into a separate port that was dropped into the rear deck. the 6x9's are in the same spot


Pimpala has 3 8" JLs firing into the rear seat with two ports firing into the rear deck through the 6x9 holes. He doesn't have 6x9's, just strong sound up front.


I don't know much about Thumps b/c I haven't seen the latest


And I'm not sure how E-Doggs is set up. I know he's got the subs under glass with suede on the panels and it almost makes my s**t look juvenile. Its a great looking stereo
