Was at Home Depot the other day and saw a little 4-guage brass fitting/connector i could screw into the frame with a small self tapping screw and then screw down the amp ground wire into the brass fitting (entire fitting touching the frame). Would that be sufficient for a ground?

I can't seem to find a self-tapping screw large enough for a 4-gauge crimp-on connector.

I routed mine from the trunk and put it under the big rear seat belt anchor bolt. Not sure if it is the best place, but it is very tight and will not loosen up. I am running 3 amps and have not had any engine noise or associated issues... I am sure that some of the stereo pros out there will have some better ideas (for both of us!!!).

Hey SSuspect. I think I'll just go ahead and do like you did. I've read on this forum and NAISSO's forum that people have grounded there and haven't had any issues whatsoever. Besides it being convenient and easy, I don't have to get under the car at the apartment and get into trouble from management

The Seat Belt Stud Is a Very Good Area To Ground Your Amp! Just Make Sure You Scrape Off Any Paint Or Debris Before Mounting It! Rule Of Thumb For The Ground: The Shorter The Cable The Better And Make Sure It Is The SAME Gauge As The Power Wire. I Just Stopped at A Car Audio Shop and Asked Them To Crimp On Some Terminals Made For Car Audio On My Cables. They Have Special "Car Audio" Terminals Such As a Fork Terminal For Your Power Wire That Fits 4 Ga Wire But Is Small Enough To Slide In Your Amp + Terminal, Same For Your Ground Wire. Make Sure You Put a Piece Of "Shrink Tubing" Over The End Of The Pos Cable The Connects To The Amp After The End Is Crimped On, Dont Want Any Accidental Shorts. Car Audio Shops Have These LARGE Crimping Tools That Do The Job Right On 4 GA Wire....Mike

Good points Builder... I used a small wire brush in my drill to get the paint off. After you connect everything, it is a good idea to re-paint the area to ensure no bare metal is showing. Not many rust issues inside, but it is still a good idea.

Slacker (or, I guess I should say X-Slacker) Let us know how everything works out!!!
