hey everyone, i have an 18" fi btl and i was wondering what amp you would suggest? i was thinking about the Hifonics BXI 2010D, im running it at one ohm. also my buddy has a 10 farad power acoustik capacitor..are they any good? this is all goin into a 1992 Chev caviler..will a yellow top battery be enough of a upgrade or should i get a high output alternator? lastly, what does it mean to have a box tuned to a certain amount of Hz? is it like port size? I've had big systems before just none of them have been ported. any help would be appreciated a ton! why drive home drunk when you can fly home high! pce boys
