shizzzon Posted February 16, 2018 Report Share Posted February 16, 2018 Just a FYI. it's pointless to measure resistance on the ground without a full load on it and Time is also another variable at play that cannot be measured with a DMM. The easiest way is to measure voltage at the amplifier's terminals during maximum output if you suspect a bad connection somewhere externally.

AlpineNut Posted February 16, 2018 Report Share Posted February 16, 2018 Looks like you done fried the power transistors from the looks of it, I can see burn marks on the prongs coming off of them. 73456w9vbwevsdb sodtbsorutnvsd sdtuspdun sd d f gsdfiusd gdf n Link to comment Share on other sites More sharing options...
nacho Posted February 17, 2018 Author Report Share Posted February 17, 2018 Thanks guys. Really appreciate the help. Two questions. When you say measure voltage at amp at max output do you mean turn music all way up then measure? Do you guys think its cheaper to have repaired or get a new one?

AlpineNut Posted February 18, 2018 Report Share Posted February 18, 2018 Well if you are like me and have some electronics background id say try and repair it, but knowing the damage that has been done and the cost of amps anymore it might be more feesable to just buy a new one with a warranty. Here are some Class-D amps. https://www.sonicelectronix.com/cat_f47-242_i24_class-d-amplifiers.html 73456w9vbwevsdb sodtbsorutnvsd sdtuspdun sd d f gsdfiusd gdf n Link to comment Share on other sites More sharing options...
