sacrichboy Posted August 5, 2010 Report Share Posted August 5, 2010 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.

dugee81 Posted August 5, 2010 Report Share Posted August 5, 2010 Do you plan on playing music with the car off? If not, you don't need the isolator (only causes unneeded resistance). Maybe get a kinetik 2000 for the rear.

sacrichboy Posted August 5, 2010 Author Report Share Posted August 5, 2010 Nope only when the car is on. What about the alternator do I need to get one that big? Thanks.

sacrichboy Posted August 5, 2010 Author Report Share Posted August 5, 2010 I have a 5 farad cap but i wasnt planing on using it anymore. Would that and the 136a alt be good enough?

Ditch the cap, get some batts, get the 260A alt, big 3, runs of 0 gauge to batts, and upp your fuses. youll be set Quote 2006 Nissan Z Track.
