You connected your batt and alt to the frame with the big 3. Now connect your amp ground to the frame... or whatever is closest to a frame. If you have a unibody, look for the thickest piece of metal under your car that stays in 1 solid piece up to the front. Most cars will have something like this because the structure of the car cannot be held together with only welds. They try to have a thick piece of metal supporting the car length-ways as that is where the most leverage would be applied. Sheet metal is often thin, very poorly connected to the chassis with a strap, and just not a very good idea.</p></blockquote><p></p>
