And I was told I need a new aftermaket Alternator. US 2000 amp is 2000 X1 Watts RMS@ 2 ohms Bridged. Can I use a 200 Amps alternator, or do I need a 250 amps one? Please help me out... Thank you
what else are you running? i would suspect you had components and an amp for them that could keep up with 4 15's
