ok first, my friend used to have this done in his 91 maxima. 2 JL 12w6's in a bandpass with a custom port through the rear deck. like everyone said, it has to be built exactly the right specs. To this day, my friends setup is one of the best I've ever heard. I watched the shop build the box and it was very difficult. It was so big that they had to build the second half of it while the first half was allready in the trunk. If you can't get it done right, i would say go for it; the results will speak for themselves.
