Ok I bought two used mtx 1501d car amps off ebay... yes before you go into bashing me at least hear me out on this one.. I took out the multimeter and tested the " Bad " mtx 1501 the one that does not play at all nor turn on... I noticed two negitive things right off the bat... Diode R115 is burnt.. But i cant seem to find the right replacement part for that one.. MTX.com has yet to call me back to help me out.. Also the out put " transistors " seen to be at a very low resistance level .364 on all for of them... They look like mosfets but with 2 legs not three . The only part numbers on the transisters i seen were U1540 and cq412 i have tried all major retail stores " digikey " mouse " etc.. but yet nothing cam close to what im looking for..
Now the good amp that does power on but has a very krazy output signal seems like the subs move but no bass... I did test the " output transistors and they tested in resistance .900 .450 .450 .900 Now im thinking that the .900 is the good ones a the .450 is the bad ones. Since the Bad amp had a lower resistance level based on that alone.
Does any one know of a direct replacement part for these amps ? the mtx 1501d is the same board as the mtx 81000d board... Any help will be helped. Thank you
Long Live The AMP GODS !
