Amp grounding help please

Just finished installing my amps and ran the ground wire to the seat frame, bolting the wire connector to the stud on the seat frame where the fold out floor mounted. I sanded the paint off and figured the four seat bolts would have to be a sufficient ground. Fat chance. I've got noise up the gazoo. Where are you guys grounding to? Thanks.

My head unit is grounded via the factory wiring harness using an aftermarket harness adapter. I can pull the head unit out and make sure the wire connector hasn't come loose, but short of that I'm not sure how I'd confirm if it's a solid ground or not. I've got a fairly loud hum with the truck off and volume at zero. Starting the engine results in the engine noise. My power cable is routed on the driver's side and RCA cables on the passenger side. It's puzzling.

Take the ground wire loose from the amp , then use a voltmeter on Ohms to check the resistance touch the leads together and get a reading (normally like .01 Ohm) Then touch one to the seatbolt and the other to the wire , subtract the two readings and thats the resistance ... The lower the better
You could have a ground loop issue and need an Isolator too
