There may be more than one problem. The fact that the radio AND the amp are seeing a voltage of 7v indicates that the battery is weak or there is a bad connection somewhere in the power line.

It's also possible that the amp is defective (shorted output transistors?) and when it turns on, it's drawing excessive current. That would cause the voltage to drop more than normal. If the amp is drawing excessive current AND there is a bad connection in the power line, the amp may begin to blow fuses (depending on the reaction time of the protection circuit) when you repair the power line problem.

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.

My battery died and I had to get a new battery. I can not remember the security code for the car radio KDC-MP342u can you help?


You may have to contact the manufacturer for details on that. Check in your owners manual for the phone number of their customer service. I had a similar problem after changing battery but found the answer right in the manual. Mine was a Kia.

Fm works, am does not


Check the antenna connection. A poor connection will often be good enough for FM but make AM reception so bad the the radios auto-gain circuits will mute the output unlike old AMs that would just produce loud static in poor signal conditions.

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.
