I have a avalanche with 2 12 l7s in a custom ported box running off of a hifonics brz2400 and while it was good for awhile I've grown accustomed to it....it's not loud enough! I have stock electrical but will be getting a dual alt kit from dcpowerinc. I don't plan on competing so I don't need something crazy, i just want to be able to do hairtricks from time to time...any recommendations for subs? Preferably 15's or 18's, thanks.
