Good afternoon, my name's Tom Brintzenhofe, certified master tech, from Reading, Pennsylvania. Today, I'm going to show you how to troubleshoot and repair, or replace a dead car speaker. Now, I've already taken the liberty of taking the door panel off. Unfortunately, all vehicles out there; the door panel configurations are different. The bolt locations, screw locations are all different, so if you're not sure buy yourself a an a repair manual and all that information's going to be in here, but for the purposes of this demonstration we've already got the door panel off. Now, what you want to do is make sure you got your radio on a little bit. You take your speaker out, your your dead speaker. You'll have four screws on it; one in each corner. I've already taken the liberty of taking two of them out, so I'm going to take these last two out. Try to keep a finger on it, or two so your speaker doesn't fall out of the door. Go ahead and pull your speaker out. Remember, this is magnetic on the back, so if you stick it to something it's going to stick, so try to keep your hands on it there. Unplug your speaker; the one that's not working, and if you got yourself a a a decent multimeter what you want to put it on is the diode side, or a voltage sensing. And if your speaker's not working at all and you want to know if you've got a signal or not before you go out and buy yourself a car speaker; some of them aren't that cheap, it doesn't matter if you go positive to negative; negative, positive on on a car speaker. Either way, it's still going to complete the circuit. You touch these two and you're going to hear a beep. That means you got a good signal out to your speaker. Now, if it's still not working now you got one choice, and then you're going to have to replace that door speaker. Not a real big big deal. Just a reverse process. When you get yourself a new speaker put that speaker in the door, hook it back up, put your four screws back on it, follow reverse procedures of puttin' your door back on, and you're good to go.
