Question about Alpine MRD-M300 Car Audio Amplifier
There are a few things you should check:
Check that you have the correct fuse on your power cable. If it is allowing too much current, the protection feature of the amp will kick in. Similarly if the resistance is too high, there will not be enough current to power the amplifier.
You may also want to check the earth/ground cable to ensure that it has a good connection.
Try increasing the gain slightly on the amplifier (not too much or you will blow something). This will mean that you don't have to turn the head unit volume too high to get a loud output.
Nice amp BTW.
