Default Headlights dimming when bass drops solution a power cap?

Hi, ok so basically i have installed a very power hungry system by the looks of it because before i had a 500 watt rms sub and no lights dimmed at all, now with a 1000 watts rms one the dashlights headlights dim with the bass. Not good at all do you think a power cap would help with voltage drop at all because on this car audio website it will help stiffen up the electrical system. Never tried this before but should i get a power cap or a yellow top optima battery or both?

Are your power and ground cables of large enough gauge to support the load?

Did you tap off the battery for a dedicated power source? Minimum / tight splices and wire lead lengths as well?

Welcome aboard too.

A cap will help the lights from dimming. I have a 1200 rms amp and sub with 55 watt h.i.d. headlights and an interstate battery and my lights don't dim. However, I do notice if I'm parked up for a while with the lights and wipers on (when it's raining)and playing music, the alternator doesn't charge enough unless I rev it a bit to about 1000rpm.
