Okay I own (not proudly) some 15" pyramid subs wit 600 RMS and 1200 Peak. Its a 4-ohm single Voice coil. I have bought a Rockford Fosgate P2002 Amp, If I were to bridge my 2 subs, would it hurt the amp or subs? Also someone told me that Rockford Subs are underated. I have 8 gage Amp wiring in my car now, since I bought this amp, is it time to step up to 4 gage?
