[QUOTE="CarAudioAddict, post: 259063, member: 545743"] ok, sounds like you are drawing too much current from the system. during long bass notes (especially in the low frequencies 20hz - 50hz) your amplifier will draw pretty close to max current. you say your Alt is only 90 amps. quick math: 80A + 30A + 40A + 10A = 160A 80A for sub amplifier 30A for component Amplifer 40A for cars electrical system 10A to recharge battery with You are drawing almost 2X what your alternator puts out, so when those bass notes hit it draws the extra surrent off your battery causing a HUGE voltage drop (put a volt meter across your battery, you may find that it drops down to 9-10 volts or even lower). You NEED a larger Alternator [/QUOTE]
