Eurovox mr900053 serial no 285001230.6. fitted to my 97 aus assy Mitsubishi. The LCD display fades out intermittantly and will not alter the volume or turn off. Even if you turn off and take the key out the radio will still continue to play at whatever setting it was at before the display faded out and will continue for some time. Hitting the side of the dash with your hand will sometimes fix the problem. I have had it to a radio shop who plugged it in on the bench & of course it played faultlessly all day. Have you come across this problem before or do you think the trouble could lie with the car?

Is your sub single voice coil or dual? If it's dual, is it wired in paralel or series? It's possible for an amp the heat up so fast, the outside is not hot to the touch. Also, the next time it happens, use a paperclip and short the 12+ to the remote wire on the amp and see if it comes on. Let me know, and be sure to leave feedback or I don't get paid

SOURCE: Car audio amp or speakers bad?

If you know how to use a multimeter, you can test the amp this way:

-unhook the subs
-hook up a cheapie speaker you know for sure works to one of the channels
-unhook the audio inputs
-turn the amp on
-set your meter to VDC
-put the positive probe on the inside of the input connector, being sure you make contact with th inner contact
-take the negative probe and tap it on the outside of the connector

What you are doing is sending a low voltage (replicating an audio signal) into the amp audio circuit and allowing the amp to amplify it. If the amp makes the speaker pop each time you strike the probe, the amp is working.

There is an inherent problem with band passes. The naturally filter out high frequencies like a crossover, including distortion, so it makes it hard to hear when the subs begin to protest.

make sure your rca jacks arent touching any metal and your hot (+) cable is not ran on top of your rca jacks and check and make sure your frequencies arent too high

SOURCE: amp keeps turning off

an amplifier needs minimum voltage (usually 6Amps) to turn on. If there is 12V at the input of your amplifier, check the remote for 12V as well as making sure the ground is secured. I suspect based on limited information, that your alternator/charging system is the culprit.Take your amplifier to a local shop and have it bench tested (abuot $10) they will hook up to an independant power supply and verify its properly working. Then it can be eliminated as the source of the problem. Also be sure your wiring and fuse are accurate for the amount of current draw.
Since your protection has never come on, and the power light is going out altogether, you may have an input voltage problem.

disconnect your speaker wires and see if it still does it. if it doesn't you either have a shorted speaker wire or bad speaker. if it still does, the amp is bad.
