jarball25 Posted May 27, 2014 Report Posted May 27, 2014 i have 2 memphis mojo 4k amps. one amp shuts off so i decided to take voltage reading across the two (Troubleshoot) when both amps are powered down i read across the power inputs and receive 14.95. When the amps power on with no load (speakers disconnected) i receive a voltage of 14.87 on one amp and 13.12. i checked all my connections and took resistance readings across the all to make sure that wasn't the problem and sure enough that was not the problem. is this a sign of early amp failure?

jarball25 Posted May 29, 2014 Author Report Posted May 29, 2014 Have you check the amp ground? yes they share the same cable and ground distribution block
Guest Posted May 29, 2014 Report Posted May 29, 2014 you're using a ground distribution block? get rid of it. amp -> wire -> frame. nothing more.
