The BEST ground location?

i see one problem with that..you are using 2 different grounding point for your amps...that can cause some noise issues in the system, its best to ground all amps to the same grounding point. best place IS the frame of the car. if your car is a unibody, the best grounding point will be the negative terminal of the battery under the hood.

im geussing you wouldnt want a 12ft. long ground wire would you:crazy:

Why not? I have one. Runs from the ground distro in the trunk of my car to the neg post on the battery. As long as it is of adequate size (larger than 4ga) it will most always provide a better ground than the sheetmetal of the car. Mine's 1/0.

nah doesnt really matter how long it is. as long as its a good solid ground. i used to have 2 very short grounds in the back grounding the back battery...and i switched to multiple runs off the - battery under the hood...and it didnt hurt me one bit. steadier voltage ftw.
