Hey guys I just wanted to know what you would recommend for a good amp. Currently I have the RF 551x 4 Ch and a Kicker 240zx amp 2 ch. They are used to power Boston Pros for my fronts and a 10" RF Hx2 sub. I am thinking of replacing the sub maybe to somethiung a little cleaner sounding and I really wanted to clean up my amps into one good powerful one to save space in the trunk ultimately, and have a cleaner sound. I have a Eclispe 8443 deck and a RF 1 farad cap as well. Thanks for the help.
