Thank you for your suggestions, right now i have a Power Acoustic 5500 gothic series. I have had it since 2006 and like it very much. It has blown 3 of my kicker cvr18s and 2 fi bls twice running one at a time at 2500 rms. Is this a powerful amp, or someone said my amp was garbage and said it blowss them because it sends dirty power to the subs? any ideas?
