Default Starter ground

Does the ground wire from the starter to the battery have or need to be grounded to the fender before the battery. And if it's not would that cause feed back through my amp.

Starter grounds through the engine, it doesn't have a specific ground wire. I think they run the ground from the battery to the fender than to the engine just to have a separate ground point on the body.

What kind of noise are you getting from your amp? Where is the amp grounded to?
Where is the headunit grounded to?

He might be talking about the ground strap that goes from the starter bolt to the fire wall.

my negative battery cable took a crap a few months back. instead of going through a huge headache for using the same spot the OEM cable was, i simply cut the old cable off at the fender and ran my new neg cable to the AC compressor bracket. havent had a single issue from using that location. and it was ten times faster than bolting it to the block. that might be easier on the 4 cyl, but for the V6, i chose an alternate route lol

The amp is mounted to the rear back seat in the extended cab the noise is motor noise and it all started when the cable from the starter that grounded on the fender and run to the battery broke in half Ii put the two back together and I've had motor noise ever since through my amp

The noise is from the alternator.
You need a choke for the alternator output or the input to the amp.
It's easier to do at the power input at the amp.

Make sure that the amplifiers have a good ground first. Use at least 10 Gauge wires for the grounds (and power). If you have 2 or more amplifiers, DO NOT go from the ground terminal of one amp to the other and then from there to ground.

If the wire that goes to the fender broke in half and you joined the two together , than the noise started in the amp, than just replace the ground with an original wire, or run a ground from each end of the original ground to the fender.

No need for a suppressor or filter if the amp did not make the noise before the ground cable broke.

I take it the amp is grounded to the body some where? Seat bolt perhaps. Losing the ground to the body, near the battery is most likely effecting the amps ability to have a good ground.

What I did in my truck when I had a noise problem, I have all my grounds for my 2 amps and crossover tying into a distribution block that grounds to one of the jump seat bolts. So I removed the stock jump seat bolt, and installed a longer bolt that goes further through the floor, under the truck I ran a short 4 gauge ground cable from that bolt, with washers and a nut, and ran it to the frame.

you're right about the ground I do think it is there. put the ground circuit Loop on it and it has fixed the problem or has fix the sound anyway I feel my problem is in that ground wire to the battery to starter. thanks for all the help
