whats the size of your alternator. I would suggest the big 3 and a extra battery for starts.

Alternator, battery, big enough power wire to carry your amperage your amp will need. Depending on you car you should be able to power a 1500.1 to at least 75% of its output. 1/0 amp kit big 3 and an additional batt in the back of the car.

I'm gonna be running around 3000W on my stock alt with an spv44 and a xs power 5100...

then again my stock alt is as big as most HO alts...

but with a single extra battery you could run 1500W IMO.

buy one of my batteries in my sig and do the big 3 in 1/0 or bigger and u will be fine.
