I have the following system... '96 Jeep Grand Cherokee 2 18" Fi BLs 2 Rockford Fosgate T10001's 1 Rockford Fosgate p500-2 1 Pair Infinity Kappa Perfect 6.5" components 1 Pair Alpine Type R Coaxial 6.5" Lots of Lightning Audio Wire Alpine CDA-7897 Head Unit + 6 Disk Changer 225 amp Excessive Amperage alternator Box tuned to about 34 hz My question is, I cannot for the life of me get my subs to play the same. They are phase, wired with 8 gauge, and the polarity is correct (as long as the subs are labeled correctly). I have the amps set for master/slave, set to give each sub 1400 watts. Does anyone know what could be causing this problem?
