[QUOTE="rich.sounds, post: 3480800, member: 581447"] I plan on running 2 RF amps, a P1000-1BD @ 1.5 ohm and a P400-4. The P1000 is rated @ 140a and the P400 is rated @ 80a. I have a stock 70a alt (99 Civic) and a new "normal" car battery. Question 1. Is 4-gauge enough? Or do I need 1/0? Question 2. Do I need a HO Alt? If so, is 120a enough? Thx, Rich [/QUOTE]
