How to test a bad crossover?

[yh125d]

My front left component set in my stereo isn't working. I've ruled out everything up to and including the inputs on my amp I'm gonna test the amp outputs later but I doubt they're broken



I can take off my door panel this weekend, but I'm not sure how to test if the crossover works. Would I be able to just do some continuity tests with a multimeter? Would a local shop be able to test it if I took it in?


Speakers are Diamond Audio D651a, new installed about 3 mos. ago

What about one of those apps that play certain frequencies?

Is it an active or passive crossover? I have components for my front left/right and they have a passive crossover that you hook up the input, then it splits the frequency to the midrange/tweeter.

What I'm getting at is if you have a passive crossover sitting in the bottom of your door it could be seeing some moisture, which causes rust. Maybe check the connections before ruling the actual crossover as bad.

Food for thought anyways...

Use a multimeter to check voltages across the input terminals and across each of the output terminals. Do this while the stereo is on.

If everything before the amp is good then it's either that particular channel on the amp, crossover or the speakers. To test the channel simple swap it with the working channel. If you get sound then it's a bad channel. If you still don't get sound test the speakers next. With the working channel connect it directly to the speakers. You'll have a midbass and tweeter so just do this for each. Keep the volume down and you won't hurt anything by bypassing the crossover for a few seconds. If the speakers work, then it's the crossover that's likely bad.
