That kind of power at 2 ohms should not be dimming much at all with you.re setup

This.

Negative battery post has factory and 1/0 gauge coming from it now did some research and ecu tells alt. How much power to put out could that be my whole problem

Most new cars do this so the alt isnt taxing all the time ...not ur problem...add that ground and get back to us ..wouldnt hurt ti pick up extra agm for future upgrades

So I'm going to have 3 grounds coming from battery should I ground to same ground as amp and battery are on now or a new one

If all your wiring checks out, you probably have your gain set too high. You shouldn't have any trouble with dimming lights with the electrical you have now.

Ground from the neg battery post directly to the amp

Battery is grounded.

Ground amp directly to negative battery post

Just try it man ..we're jus tryin to help.u shouldnt have any dimming at all but u clearly have a install or equipment problem

How did you set the gain on your amplifier? you should go to an auto store and have your alternator tested, they usually do it for free

 

[kirby mane 10+ year member]

Amp was set with meter and alt was tested at time of purchase
