jarball25 Posted May 27, 2014 Report Share 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?

Guest Posted May 29, 2014 Report Share Posted May 29, 2014 you're using a ground distribution block? get rid of it. amp -> wire -> frame. nothing more. Link to comment Share on other sites More sharing options...
