what is your battery setup?
What cables/type/gauge?
Do your lights dim, are the amps cutting out at all?

A while back a Jeep guy had the same issue. Did the Big 3 and regrounded all the OEM grounding points. That significantly improved the lighting. Still did it but barely noticable.

What amplifiers do you have? What subs? and running @ what Ohm load?What size is your supply wiring to the amp/amplifiers and fuse size under the hood, to what size make and model battery? Any secondary batteries at all or two? Has the Big3 been done yet? What size is you ground wiring at the amplifier/amplifiers? where is it grounded to?
More Information needed to try to diagnose the issues/issue
