Please don't say "brag" about rockford fosgate subs with a box that doesn't fit in the trunk and a boss amp...
...Now that that's out of the way! You dropping 500 RPM isn't because the subs are drawing too much power. I've got a about 250 watts RMS on my mids/highs and 2600 watts RMS on my 2 10"s in my FRS and, while I do get headlight dimming, I only see a drop of MAYBE 50 RPM (yes I meant 50, not 500) when the bass hits hard even at idle. I've run this setup with the stock battery as well as an optima yellow top that I upgraded to. Yes I'm still running the stock alternator while I wait for my custom 320a alternator to be built/shipped. It's probably something messed up with your wiring if anything or a deeper problem.
Also, whatever you do, do NOT put a capacitor with your system. They are terrible for your cars electrical system if you don't have the alternator/batteries to support what you have and basically just work as a buffer to help with long power wire length.
