General Car Audio Discussion & QuestionsAll general car audio discussion goes here. Need help installing speakers, headunits, amps or electrical? Having problems with equipment? Have questions about a product, post here.
I have one connected to the amp distribution block to get amp voltage and one one my "factory" wiring behind the dash, just like b-shot. The way they are wired, and the fact that I only have batteries in the back (nothing underhood), if voltage suddenly drops on one meter instead of the other I can figure out which fuse has blown or if there's an alternator problem.
