The only actually grounding you are getting is through minimal contact with the bolt and washer on the other side. I'd take a dremmel to the paint below the ring terminal for maximum connection //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

wow i just scraped all black around it off, and it still will shut off around 45-50 with bass on 2 and hpf on 100hz.

Make sure you get all the paint off down to the metal. Just because all the black is gone doesnt mean your down to metal.

i have a pioneer so its out of 62

its not like i want to go to 62 its just i want to be able to play it around 45-50 area with bass 3 and not shut off.

i dont think the ground is the problem, though they can be improved. how high is your gain? maybe lower it and leave your subwoofer at -+0.

Subsonice-Middle

How long does it take for the amp to shut off? What kind of car do you have? Sounds like it could be your alternator is going out and your amp is protecting itself or you may need a High output alternator. Well looks like you have an aftermarket alternator. You may want to check and see what the voltage reading is on it with multi meter.

Also what kind of subs are you running? dual 2 ohm dual 4 ohm single 2 ohm or single 4 ohm etc. How do you have them wired? Could be sending amp a load it isn't stable at.
