What is the best way to ground a head unit? Should there be two different grounds?(the ground wire and the radio chassis) Should the ground wire, and the head unit chassis ground wire be in the same place? Or will the stock ground lead work and then ground the chassis to a place near it. thanks,

The chassis of the radio generally takes care of it's self, most dashes have steel around the radio mount. The biggie is to NOT use the factory ground, in my experience, it's a terrible ground, and if used, your radio will find a better ground through your antenna lead. Use a dmm and find a ground point that gives you the smallest voltage differential, then use it for your deck. Same goes in the trunk.

If it dont fit, force it... if it breaks, it needed to be replaced anyway...

I have a $30 digital radio shack multimeter. Do you mean that I should use my +12v lead and find the ground that gives the highest voltage reading? or the lowest resistance? I can't thank you enough Audiophyle, I'm building the box for the Oz 250s next week. I'll let ya know how it turns out

I once had a problem with alt noise, when I hooked up my DEX-P1r and the local installer said to Ground it the same place that the amps are grounded he told me to run a Primary wire from the HU to the place where the amps are grounded, result no more noise.

best way i have found so far is to take the ground off the deck and chop it kinda short. Then solder a 10-12 gauge wire to it that runs to a new ground spot on the car. Makeing sure that the metal spot you are going to use is actualy conected to the chassis, not to plastic.
