Re: Getting bad voltage drop.
The amp is grounded to the body right? My '89 chevy had nasty dimming lights with a 1000 watt amp grounded to the body, then later with 7000 watt amps and direct to battery connections didn't have any dimming. Run body to chassis ground cable, ground directly to frame, or directly to battery. If already doing that then I typed all this for no reason and nevermind...
