Nope, i don't have those problems. I have about (450+500+150=1100) amps of power, plus a car computer, along with a 1 farad cap, and no problems.

I do run some pretty heavy wire back to my amps (0 gauge), along with a good grounding kit in the engine bay to preclude any power loss along those lines, so maybe that has helped?

Also, I have an 05; do you know if the alternator is stronger in the 05's than the 03's? Just a guess.
