What I found out is that the red connection of the RCA is the only one that when I turn it makes the humming or buzzing almost like pink noise but stays at a certain frequence or note. I know it's not the rca's since I tested it with two other rca's I had laying around

I did 2awg but only did 2 of the three only one I didn't do was the chassis ground the agm battery was 160 to 180 can't recall the price on the top of my head but I believe it has 800 to 820cca. The ground for the RCA what would be a good type of ground I should ground it to like a bolt or to something metal in the general location and would it be okay to add wire to the ground to reach a or the ground location or will resistance be a factor in a good ground the amp ground seems fine I have a brass or copper ring terminal and have it bolted down to the metal siding of the trunk and grinded down. If you would like I can take pictures of the ground wires and any other pictures needed to see or have a better rough guess to my problem

Amp: ken wood x1200m Amp gain: Lpf 100hz isf 20hzinput sensitivity slightly over 2v hpf on head unit is 100hz. Sub wiring is 4 ohm load and the subs are wired out of phase. Currently using the stock battery for starting of the car and to power the amp and subs. Replacement since the stock was 80a and the newish on is 130a. Ground of the battery is the the strut tower with grinder down paint I'm ground to the chassis on the battery just missing the the upgrade battery to engine ground for amp ground it's in the trunk and it was grinder down with a wire brush and drill same with the other ground.

Okay this is the second one I'm posting of this the update is I replaced the 8ga to 4ga and I'm still getting light dimming so far I replaced the alternator from a 2003 highlander and did the big three so I'm guessing the battery is left to replace or do i have anything else to fix before replacing the battery
