A solution to a temporary problem is required. What I'm looking for is a specific answer, if anyone cares to help.

Currently my CD receiver and empeg share the same power line by use of a T-Harness. This harness was designed specifically to keep keyless entry (which is inside the factory radio) after an aftermarket head unit has been installed.

Anyway, because they share the same line, when I turn up the volume on the CD player, the empeg no longer receives enough voltage (battery icon). I would like to be rid of this CD player, but I won't be able to afford an external amp for a little while.

So, would someone please tell me specifically what gauge wire I should use to wire the empeg's constant power (yellow) directly to the battery, and what size in-line fuse I should use on that wire?
