I have a 2001 blazer 4 door and i have hooked up 2 amplifiers on the rear of my seats on those little panel things that go up and down when you put the seats down/up. I have my amplifier grounds on one of those metal things where the bolt goes, I have cut the little rubber-ish peice of carpet that was there to get contact with chasis... Is this a good spot or should i find another spot?? Because when i turn up my volume, my sub cuts out and i feel as if i dont have a good ground. I have sanded the area down a bit. My amplifier uses 4 gauge power wire, i have a strand of 1/0 oxygen free tsunami compotition power wire. Would that be better than the 4 gauge oxygen free copper power wire that is there already?? Where do you have your grounds positioned?? Input is greatly appriciated THNX

Give it some time, bro.
Not everyone here has done a sound system in their truck.
Also, Their are many people who are just unregistered guests browsing the site, so they can't reply anyways.

 

I bolted mine to the rear seat bracket, I sanded down to bare metal and used the back seat bolt to ground my amp. hope it helps

 

hmm... Imma check that out hopfully tommorow if the rain doesnt stop me. THNX

 

you can do as the other guy said and bolt it down to the seat posts. thats what i had till i moved everything to the rear of the truck. otherwise, you can do what i did for my new grounds. completely sand any area until it is bare metal, get some sheet metal screws, drill a hole a little smaller then the screw because they are self tapping. otherwise you can find any other bold and sand that down and youll be good.

 

I did the same thing as slammed95 did. Scraped off the coating or whatever then sand down to metal and use a self tapping screw. No problems with amps shutting off or running hot. I also did the big 3 and a few other extra grounds. Remember with grounds the bigger and shorter the wire the better.

 

I drilled through the floor and took mine right to the frame

 

i use phillips head self tapers, and a crimp on copper ring. sand to bare metal and make a new hole. i also usually run the big 3 and extra Frame-2-Chassis straps (about 6 for a blazer) just to make sure its good.

 

I did the same thing you talked about just make sure that you get it down to bear metal and get good contact and tighten it down. mines been ther for over two year with no problems running 1000 watts to my L715" good luck.
