Troubleshooting Car Audio Amplifiers

Video Transcript

"Hi. My name is Teddy and I'll be showing you how to trouble shoot a car amplifier diagnostic. The first four things you need in a car amplifier would be your constant power, your remote power, a good ground and your RCA signal. So if something goes wrong with your amplifier, these would be the first things you'd want to check. By using your standard twelve volt test light, anything that you can pick up at your auto parts store. So after finding a good grounding spot for your test light, you'd first want to test your constant power. If you get a light, that means your constant power is good. Then you can actually test your remote power with the car on. If you don't get a light, usually that can be one of your problems, you don't have remote wired and you'd want to test it where you hooked it up. If the fuse blew or if the wire came unconnected. If you don't get a signal off of your power wire, again you would want to check to see if the signal running to your battery, the fuse on that blew as well. A way to reverse it to check for ground, you would want to put onto your power wire the signal. Stab into there and onto your ground and then test it, it should also be lit up. If you don't have it on there, it means either your ground has come undone or you don't have it ground to a solid point onto the chassis. After testing those three, if your amplifier still does not work, you would want to check to make sure your RCAs are plugged in or there's no break in the RCA point. A way to test if your speakers are working actually as well, is you can use a nine volt up to a twelve volt battery, test the positive and negative to each of your wires. And you'll be able to hear a small popping sound off of your speaker and that will tell you if your speakers are connected right. So the four things you would want to look for is making sure you have continuous power, remote power, ground, your RCAs are working. And then if everything still, if everything checks over good, then you would want to continue to check if your speakers are working by testing with a nine volt battery."
