A question about using car audio amplifiers in W126. Assuming you have the amp/s in the boot, where's the best place to attach the ground cable ? Is it possible to do this without scratching paint ?

How about running a cable all the way back to the battery ?

Thanks!

There are two factory grounding points in the trunk.

I tried the one on the right-hand side of the trunk and found that it worked for my installation.

I'd try one of the two grounding points and then, if you have alternator whine, try a dedicated ground cable back to the battery. Just make sure it is of the same gauge as the positive cable.
