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.

Thanks
