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.
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
The radio uses a constant power to retain memory(stations,settings,ect.) and switched power to run on. It sounds like there is a problem with the constant power connection. You can first check the fuse box for any blown fuses and replace any that are found. Also look around the battery for any wires with an inline fuse that could be broken. Try looking under the dash near the radio for any inline fuse holders that could have a blown fuse. You might need to pull the radio and start tracing the constant 12v power wire. First verify that it does have power and if it does then the radio may have been damaged from a voltage spike when the new battery was installed. If the wire does not have power then you will need to start tracing the wire back to the source of the short. It sounds to me like a blown fuse somewhere....
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.
