Also check to see what your regular battery is floating at. Might need a better battery as your original and then add a 2nd and do the big 3, that is what I usually do when I run more than 1000rms. Might not need to do all that, but just throwing it out there.

What size alt?

Big 3 and HO alt will stop the dimming.

I'm amazed how many people run 1000+ watt systems and don't improve their electrical.
