You have definately blown a output channel, or power supply. Send it in for warranty.

With the Uniden UH7700NB How do I tell which is positive and negative on the power input THANK YOU


You can connect the radio to any standard 12 volt DC power source, with either a positive or negative ground. If you don't know whether your power supply uses a positive or negative ground, consult the manual for your power supply or contact the manufacturer.

Replace your battery. It's dead I feel. You can try to fully charge it up but if you had to replace the fluid in the battery it does not sound good. Make sure your battery cables are tight and clean on both ends.

My 2002 mazda mvp ausio system is not working but I can insert and eject the CD but cannot do the in tape cassette also the display is not showing the clock or any thing plz any one tell me whats wrong...


Internal board damage. Also the ribbon cable for the soft load on the cassette is not engaging. This can happen due to just ware from the age of the unit. Cold solder joints are usually the culprit, that is why the display will not light. Check yards for a newer used deck it just might be easier unless you have a shop you can send it to.

Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

RCA CABLES


RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
