Is this a good place for the ground wires from my amps? they are holes that a fold-down seat bolted to in my truck, and i sanded the paint off. I just want to make sure because I have a 50 lb sub/box sitting right on top of where the cables are bolted, but i also have a custom support holding most of the weight. Also, I recently had a new rear window put in and the guy who did it didnt seal it completely, so now when it rains i have water dripping in on my sub, and i found underneath it around the ground cables to be a little wet too. everything is working good, but can a little water cause any problems? im getting the leak fixed immediately.
Might want to air out the inside of your truck when you know it got moisture in it. Your ground should work just fine, other than the box teatering in the bolts. Might try to locate the exact spot of leak, and try some ole trusty silicone inside and out till you can get it fixed correctly.
