I have a 1971 Impala with an Alterstart 135 amp alternator. My question is do I need a bigger alternator if I never intend on playing my system with out the car started? I also wanted to know if it would be better just to add a trunk battery or add both a bigger alternator and battery? My system consists of:
1 = MMats 3000.5 amplifier (2500 watts rms @ .5 ohms w/12 volts)
1 = MMats SQ4150 (4 x 150)
4 = Kicker S12L7 D4 (parellel/parellel to amp to give .5 ohm load)
4 = Boston Acoustic 6.5" inside speakers
