Please Help with Amp sizing

Chris Murphy New member Username: Cmurph0009 Post Number: 1 Registered: Jul-04	Posted on Friday, July 02, 2004 - 03:42 GMT I have 2 15" Rockford Fosgate RFD2215 600w RMS, 1200w max subwoofers and am not sure what size amp I need to power these. Should I get one larger amp or two smaller? Thanks

But you WILL need to upgrade your alternator. You add 10amps for every 100watts so you will need 120 amp larger alternator. P.S. Be sure to add this 120amp and your car's current alternator together to get a total. You will prolly end up needign about a 200amp. And also be sure to get a good 4 gauge amp kit.
