Got an issue: when I'm at a red light and I'm using my system (6' front door menace audio door speakers, 6x9 rear deck speakers also menace audio, 2 10' kicker L5s, 1,000 watt 4channel menace audio amp, farad 2.2 cap, lighting audio dual fuse block, pioneer headunit, amp is hooked up to a switch to turn on & off power) and the bass is hitting hard my headunit will shut off and turn back on and my headlights dim also...what could it be?

Also I have put in a brand new battery in my car and a newer alternator that was tested to be good...the stock alternator runs at 65 amps...

Well just the headlights pull 5-10 amps, then the radio pulls 5-25 amps. So you are already at 35ish amps of current before the 4ch is even on. You are pulling waaaay more current then the alt can supply. Either that or bad radio grounds

Get a volt meter in there some where so you can monitor it. Your volts are probably dippin so low your **** is shutting down.

I would suggest a bigger alternator and second battery. I swapped out my capacitor for a second battery and immediately noticed a difference in voltage drop. Less significant and my second battery really isn't that big. Just a Shuriken BT20. But i suggest starting off with a bigger alternator and then onto a second battery.
