First time installer needs help!

[irskragos]

Hey guys I just bought a bunch of gear to install in my 04 cadillac cts and I don't know if it will be able to fully power the two amps that I have. The two amps i bought are the rockford fosgate r1200-1d and a alpine mrp-f300. My alternator is rated at 120 amps and my battery is a duralast 78-dl. I don't want to get a cap so I'm guessing I might need to upgrade my battery or alternator. Can I get some advice on what I should do?

Caps are crap.

Based on 1500W RMS max, I don't think you have a lot to worry about. I'd say install it first and then you can use a DMM and see if you are in need of more power.

Go ahead and do your Big 3...if you are having problems try replacing that battery with something more audio savy
