Hey guys, Ive got a 15" XXX run off a Soundstream PCA-2000D. Its in a 7.25 cu foot box tuned to 33 HZ. It sounds awesomebut as I expected it is really missing out on some high end bass. I was thinking of throwing a couple 8's or a 10 in on a separate amp, which would work better? Also, I need to upgrade my electrical. im for sure gonna do the big 3, but would I be better off replacing my stock battery with a deep cycle, or just running my amp off of its own deep cycle battery. and if I ran a separate battery, would I be getting less volts to my amp with the lack of the alternator? Any help with this stuff would be a big help. When I get my box carpeted Ill post some pics of it, and hopefully see some of you guys in some western canada SPL shows coming in the new year.

Cheers
