Radio powers up but no sound

Check the speaker wires maybe they have worked loose. And speakers themselves as they may blown. Do you have an amp if so check its fuse. Also check for inoperative interior lights, lighter, and horn. One of these circuits will power the radio's memory circuit. Some radio models will appear to work normally but have no sound if the memory fuse is blown. The clue is the clock will reset to 12:00 each time you turn on the ignition switch.

You have a fuse for the factory amplifier. It will be lo ated in the fuse panel.
A thumbs up would be greatly appreciated

Hi Toxey.

Does your trunk amplifier got power.
basically amp need remote power input it is coming from your radio.
please check when you turn on the radio remote power must turn on.
if no it is radio problem or wire is damaged itself.
please check the outputs,speakers with multimeter or single 1.5v cell.
if power is ok.and the remote on signal is ok your device still not working , it is the problem with power amplifier unit.

please check and let us know the status.
regards.

Check that power is actually getting to the radio. A cheap multimeter will do the trick. Connect the red tester to the power supply and the black to any earth (-ve). The body of the car is earthed so any bolt into the body will do.

Check that the radio doesn't have its own inline fuse which could also have blown.

It takes quite a substantial fault to blow a 20 amp fuse so take care, there may well be a dead short somewhere.

Could be speaker fuse or fuses esp if played loud with bass turned up worst case is power transistors blown then you may as well scrap it considering cost of repair vs second hand radio. Look at wires coming out of back of radio to speakers for inline fuse holders push and twist to open.There could be a fuse in rear panel of radio. Sorry I can't tell you how to remove the radio

Check if any mute function is not activated.

Radio sends a 12V signal that switches on the amp which has it's own power suply but won't switch on till signaled from deck. Check to see if the amp is powering up.

There are two supplies to a car radio, 12volt ignition and 12v perm live.
sounds like you have lost the 12v igniton as only the basic functions opperate, check for fuse either on the fuse box, accessory fuse, (sometimes marked as 'radio') or on the back of the radio for an inline fuse.
