Question about Jl Audio 1000/1 Car Audio Amplifier
If the battery is at or above 12v and the voltage at the amp (measured directly across the terminals of the amp) is 5v, that would require hundreds of amps of current which should easily blow the 80 amp fuse. If the fuse is defective, is would account for the voltage drop without excessive current draw.
Have you checked the ground connection between the amp and the vehicle's chassis ground point?
