Copper ground wire for amp, to steel body.

[Z2TT]

Hello,

The ground wire I used for my amp was a copper wire with a ring type end. The amp was mounted under the seat, so I scraped back some of the paint around the bolt hole for the seat to reveal the steel, and put the ring end around the bolt hole, then put the seat on top of it and tightened the bolt down, it holds very firmly but I'm worried because the ground wire is Copper and the Car body is steel will it just corrode and lose contact because of the dissimilar metals?

Thanks.

They will be fine.

Copper and steel don't produce a nasty reaction like ali and galv does.

Just make sure the earth wire is at least the same size as the power wire

Nah, some of its aluminium, some of its tinned copper.

There is a variety out there.
