I just purchased a memphis audio Mojo 2500 amp. Want to know how much power I need to run it. all together my total system wattage is around 3000 watts. I know I need to upgrade stock alternator and also plan on running a extra battery(s) if needed. Any help would be appreciated.

Im using it to push a Memphis Mojo QVC 15( old style).

Ive been told to add up all the fuses that you have in all your amps and stuff and that should give you a rough estimate, but Im sure if you upgrade your alternator you would be ok, I cant see why your stock alternator cant handle one 15 though

Just divide by voltage. Considering you'll hold a 14.4 thats the highest you would pull.

Then it depends on the product you buy and wire you use. Efficiency.
