need some help with the power wires and the ground

on my aftermarket stereo it has
constant power
ignition power
ground
power antenna wire (which can be used for the remote for the amp right ?)

OEM unit has
constant power
ignition power
chassis ground
and another wire that runs to the fuse box (2nd ground ?)

now im wondering where do I plug my stereo ground, right to the chassis ground or to the wire that goes to the fuse box if that is a ground

What color is the wire going into the fuse box that you think is a ground?

You can ground the stereo yourself.

its red/blk
I think I've figured it out
that wire is used to light up the display on the stereo

:happysad: I didnt think any live wires went into a fuse box.

there shouldn't be any... almost sounds like a previous owner hillbilly rigged something

your aftermarket stereo should come with a remote turn on wire.

If absolutely neccessary you can use the power antenna wire, but some units will turn off the antenna(i.e.-no power output) if you put in a CD, tape,etc. So your amp(s) would also cut off, I'm guessing you don't want that! As far as grounding the head unit, simply plugging in your antenna will ground it, if you are at the point of guessing which wires are which. Better to do the safer route(W/the ground) than plug up ONE wrong wire, smoke in 12v isn't your friend!
