First don't even consider a cap an option. Second do you have a big 3 upgrade and do you know what size alt you have stock? At most you might have to do big 3 and add a small battery.

Do the big 3 under your hood and add a small car audio type battery near the amplifier.....NO CAPS!!!!!!!!!!

caps are a waste, just go with a small battery like stated above

Big 3 and proper grounds could removing your dimming. I'm pushing about 1500 or so watts on a stock 130 amp alt and a standard battery with no dimming at all unless I've got it full tilt, then there's slight dimming.

Many people forget to sand all their grounds down to bare metal. And make sure it's in a good location, I checked out my friend's ground and he had it going into a plastic brake light...

Most capacitors suck ass.

Do a big 3, 50-60 amp hour (batcap, shuriken, xs power, kinetik, etc.) 2nd battery, big 3 in 0 gauge, possibly upgrade alt if you can afford it.

Big 3, definitely. Helps just about everything.
