Question about MTX RT404 Car Audio Amplifier
Hi, In our boat, a wire running to the Front RH speaker, was pinched in a steel on steel joint. The wire was cut thru and earthed on the frame, subsequently the RH channel (front and rear) is no longer working, the left works fine. Both speakers are also stuffed, when connected to the RH channel the magnets on the back of the speakers get hot. Is this fixable, or have we destroyed it? (BTW, we've already made changes to prevent the pinching happening again!) thanks in advance, Steve in Australia
The output stage of the amplifier (RH channel) was probabla damaged from the grounded cable. The heat in the speaker means that the coil (d^speaker) is recieveng DC power from the damaged amplifier. Audio amplifiers are not special and can be fixed. In many cases, the output stage is a power MOSFET or a power audio amp IC. The only issue is the availability of the parts in your area.
