Moisture in amp while on, caused a small pop, then no sound outpu
I own a pheonix-gold M44 triple darlington high definition amplifier, and it has worked very well for. I have it intstalled in an s-10 extended cab behind the drivers seat on the floor board. The situation is that a little snow got on the amp on the top left corner of the vents. I brushed off the excess, but didn't unplug the amp, so after about ten mins. of driving(amp was working just fine) I had the radio on, and i hear a small pop come through the speakers and then the sound is gone, and the OVR(red light) is blinking on the amp(solo flash of light with a 1 sec. pause in between blinks). The fuse inside does not appear to be blown.

You've got the gain to high and the amplifier is clipping the sound frequency causing it to distort. Possible problems are you have a bad speaker(s) and the reading is below 4 ohms. Each of the 4 channels can only take 4ohms. If your bridging 2 speakers to this amp you have to also make sure you are only bridging 4ohms anything lower will cause the amp to overheat. Dont put 2 speakers in parallel on one channel or you will definitely have more problems.
First I hope you remove the speaker wires from the speaker that come from the built in amplifire. You cannot hook the powered sub to the amp without doing that first. Then all you need to do is run speaker wire from the sub out of the box to the amp. In no way can you hook up any other part of the powered sub, but the sub itself, to the amp. If you know the wattage of the sub and the ohms then wire it to the amp correctly. Your phoenix amp will put out 125 watts x 2 at 4 ohms and 250 watts x 2 at 2 ohms and 500 watts x 1 at 4 ohms bridged. Remember, only the sub itself in the sub enclosure can be connected to the amp. Hope this helped you. Let me know if you need more help.
I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.
