Ok, if someone can help, i'd be so appreciated. I have a pioneer deck, planet audio pre amp rockford fosgate t1500 amp and 2 12 inch kicker l7 in a big ported box with 0 gauge wire and two batteries. I have speakers at 4ohm and it hits really hard and clean on certain songs and deep hits, but really crappy and unclean the rest of the time. I had it wired to 1ohm and coils were burning...I took it to stereo shops and they keep telling me different things, and ive spent a tremendous amoubnt of money already. Ive heard l7s b4 and they hit hard and cleaner with less power. any help please
