SOURCE: Sony X-Plode amplifier. NOT working

It is possible if the model amp you have is bridgable to 1 channel. Usually when you bridge an amp you will need to hook one wire to the positive side of one channel and the negative side to the other. You will need to consult you user manual for the amp or get the manual from the sony website for instructions on how to bridge the amp or if the amp is even bridgable.

Subwoofer is not playing


It is hard to say. The sub-woofer has its own amplifier, although it is supplied the sound data from the main amplifier. It could have a problem with the battery power circuit (Sub-Woofer Amplifier Connector Pin 6, LIGHT GREEN/VIOLET) or it could have a problem with the GROUND circuit (Pin 2, BLACK/LIGHT GREEN) Or it could possibly not be receiving the signal from the main amplifier (Pin 7, BROWN/ORANGE "+"), (Pin 8, RED/BLACK "-"). Or it could be that either the sub-woofer speaker is blown, or the sub-woofer amplifier is defective.
There is also a "High Audio Mute" circuit that connects between the main amplifier and the sub-woofer amplifier.

It wont light up and when i hook up the kicker it goes hay wire with out put but its not the music


If you are hundred percent sure that your sub woofer is working correctly, then it would indicate that the amplifier is faulty. Component failure inside will probably be the cause of your problems. Take it in to a qualified repairer to sort out.

My amplifier turned off while playing and wont turn on at all now


Hello, it sounds like you shorted the outputs of your amp or the power supply mosfets shorted. Very common when people have the music at a loud volume. Does the protect light come on? If not then the power supply is probably shorted not letting the protect circuit get any voltage. Some amps do this and other amps if the power supply shorts have the protect cicuit built in such a way that if the power supply shorts out the protect circuit still works. Cause you checked all wiring and redid it and no fuses blew then this is your problem. I repair amps everyday for a living. ?Most of my out of state customers are from fixya.com. I'm the cheapest amp repair business you'll find. If interested send me a private message letting me know what kind of amp it is, name and model number, and i'll get you back up and running with warranty.

Whirlpool oven: oven bulb popped and oven wont work. I already replaced the bulb. Does it have a reset switch? The stove top still works fine. The gas wont come on in the oven so that I could manually...


Sounds like you have an open cicuit in the oven power. The control for the gas uses the impedance of the hot surface igniter. Check for a circuit breaker. The wiring diagram should be inside the control panel cover.

The problem are worsen that before. It is wisely to replace both left and right amplifier
IC, but make ensure that the power supply feed a good amount of voltage to amplifier,
Also a strong good signal. Be sure to measure it.
