if you have a multimeter, make sure the yellow is connected to a constant power source. turn your key to the off position and see if the yellow wire still has 12 volts going to it.

If it ain't turn on at all check your fuse box. It could he a fuse under hood in car under dash. If the fuse is good then pull the radio out. Do a smell test on it. If you don't smell anything suspicous then check your red yellow and ground wire. Yellow being your switched 12v which turns off and on with ignition. Check red wire also. Also ground wire is very important.if none of those work it will need to be replaced. Check fuses carefully. A blown fuse can sometimes be easily missed

Hi nick, there can be many causes for this fault.
1. your speakers or speaker cables are faulty, then this problem will come up.
2. your installation is done incorrectly, or with the wrong gauge of power cables can cause this problem.
3. your vehicle battery could be weak.
4. you could have an internal problem with the amp only, which needs repairs.
cheers.
