So today, I'm going to show you how to bench test a car stereo amplifier. First, we have to hook up some power. You always want to hook up ground first. Now we're going to hook up power, and now remote turn on. Our power light is on, so we know we have made our connections and at least the amplifier shows us that it's turning on. Now, we're going to check and make sure that it has output. So, we're going to get a test speaker, one that we know works, and we're going to connect that right here, connect the second lead of our test speaker here, and now we're going to use a device called a tone generator.
