I was wondering about a few things. I have a sub amplifier that has a fuse rating of 140 amps. Im trying to figure out what I should do. I want to get a second battery and a 260 amp alternator from DC Power. I was thinking about using a battery isolator also. If you guys could help, that would be awesome. Oh also, I have the factory alternator rated at 134 amps, and a Yellow Top Optima battery.
Thanks.
