[QUOTE="grandam888, post: 7351200, member: 628519"] also check gains, set with DMM to proper voltage in AC volts. the calculation is square root of (rms wattsXohms). IE:500 rms watts time 4 ohms =2000 square root of 2000=44.7 volts AC. do this with radio turned up to NORMAL listening volume playing a 50hz test tone and dmm connected to the + and - terminals of amp. test with dmm in AC voltage if its still not "loud" enough. then your probably expecting too much out of your system. also do not use any bass boost etc. all your going to do is send your sub a clipped signal. clipping=burnt subs. (improperly adjusted gain is just as bad) [/QUOTE]
