CD players aren’t as long-lived, though they can deliver 5 to 10 years of service.
How do you test amp output?
Insert the Test CD into the source unit. With the A.C. Voltmeter set to ~ AC VOLTS, in a range of 10 to 100 Volts, connect the voltmeter (+) test lead to a single channel of the amplifier (+) output. Connect the voltmeter (-) test lead to the same amplifier channel’s (-) terminal.

How do you test an amp to see if it works?
One of the quickest ways is to simply touch the power wire from the amp to the positive post of the battery and the ground wire to the negative battery post. If the power light comes on, it can be ascertained that the amplifier has a good circuit board.

Use a flashlight to check the bottom and the power. If the links are loose, tighten them. If the connections are loose or perhaps you’ve blown a fuse, the amplifier will not give any output.
