Auto Repair Do It Yourself?

Good afternoon! My name is Tom Brunch, a certified auto mechanic from Redding, Pennsylvania. Today we’re going to learn how to troubleshoot car stereo speakers.

If you’re not sure how to take it off, get yourself a repair manual at a local parts store. They’re around $12 or so. So a lot cheaper than breaking a door panel. Once you get your door panel off, locate your speaker or speakers and your door. If you have a speaker that’s cracking the noise and is a little distorted, chances are that you’re going to need to replace that speaker.

This particular speaker here isn’t working at all, so we’re going to go ahead and take the speaker out and I’ll show you step-by-step on how to troubleshoot on whether or not it’s the speaker or if it’s the radio or the wiring. We’ll go ahead and take these couple of screws out.

Try not to let speak or fall out of the door. If you’ve got a good speaker, the last thing you want to do is poke a hole in it. Carefully unplug your speaker in the back. There’s a small tab that usually holds it in. Just push it in and pull it right out. You want to set this on a diode section or voltage sensing. If you’ve got a signal, this will automatically beep on you. There are two wires in this plug.

It doesn’t matter which way you hook these up. As long as there’s a second when you plug it in and it’s beeping away, you know you got a good signal out here. Next thing you need to do is just replace your speaker reverse process.
