Ok for the last year ive been running 2 15" L7's each in their own sealed 4cu ft box, and powering them with a Audiobahn 18001DT digital Class D monoblock amp. This setup sounds incredible on low notes which I love, specificly 26-35hz.

my questions are, If i switch from the 1800rms amp to a 3500rms SoundStream PCA3500D amp will i hear a big diffrence SPL wise? also would I blow the subs? Im currently running my stock 140amp alternator and the fuse rating on my current amp is 150a, do i need to upgrade? if so would i hear a diffrence in spl?

Thanks guys, just looking for advice..

simplest solution i would say is square port those boxes & face them 4ward , should be a noticable difference .....

thanks for the compliments, and rick ross - no they dont hit the back of the trunk..

well im pretty scared that if i go ported only a few notes will be loud, where as now i have a wider range. Am I wrong? Also I wanted to try and fit 4 turning the whole trunk into a box but was scared i wouldnt be able to squeeze the air space ide need to hit those ultra deep notes that i love..
