Non-JBL Debug of right channel extreme low volume

the jbl speakers are lower resistance; I'd expect them to be louder. I would want to check the wiring through the door jam into the door to verify it was done right. body shops tend to do shoddy work even if they paint well. they may have butchered your wiring or the speakers.

 

Visit an audio shop. They should be able to diagnose the problem in a matter of a few minutes and at minimal cost........IF they are competent.

FIXING the problem might be a bit more difficult, depending on what the problem IS.

 

Probably woofer speaker wires are disconnected at some point. Maybe at speaker? Or where wires go to door or either side of that?

 

Well if you really INSIST on trying to fix this yourself.......yes, the wiring would be the next thing to check.
Disconnected or possibly pinched on something and shorted.

Is there some reason that you do not want to take it back to the place that did the previous work ???

 

I’m just giving advice because OP asked. If it can be taken back to whoever did the work originally then I would just think that OP would have already done that.

 

Wiring doesn’t separate into front and back doors. Bought front and back speakers are connected to amp separately (otherwise fader wouldn’t work).

 

Yes. There is amp in the head unit so technically my post was correct.

Looking from wiring manual it appears that jbl amplifier has separate output for tweeter and woofer. Right woofer connects to front door by pins 5 and 8 and tweeter by pins 1 and 2. Regular version has only one pair of wires going into door and they are connected to pins 1 and 2. So what your front door is no doing is directly what is caused if you install jbl door to non-jbl car.

Rears should work so either they messed something up or something is broken.

But fixing that front door is somewhat problematic. Because you could just connect wires from tweeter to woofer but then you don’t have tweeter anymore. And I think jbl speakers are 2-ohm and non jbl 4-ohm so head unit amp is overloaded if you do this.

You should really just make that shop put non jbl door/speakers in…

 

Are you sure they swapped in your woofer speakers? Because if they did they would probably also swapped in our old tweeter and crossover and then it would have already worked. If they didn’t you shouldn’t do what you just did. Your stereo head unit may break!

You can test this with multimeter non jbl is about 4ohm and jbl is 2 ohm. You can’t know overloading by sound you will only notice it when sound stops. And then it may be too late.

And now why know that problem wasn’t with the car before it did get to that shop. But they caused it. And it is pretty easy to explain them how. Jbl and non jbl speakers and wiring is not the same. So you should just get it back to them so that they would fix it. And only correct fix is to install non jbl woofer, tweeter, (I think crossover is integrated into tweeter) and wiring harness.

Cause of this thing I always do everything that I can myself because you will spend more time fixing other peoples faults than just fixing it yourself. But you should get them fix it because fixing it yourself will use money and you used it already by hiring shop to do it.

 

Are you sure they didn’t only swap the part with the logo? JBL model has crossover non jbl doesn’t. It’s probably integrated to tweeter.

Maybe they swapped the tweeter cause that’s easy. But I highly doubt that they replaced woofer because that requires drilling and pop riveting. And I don’t think that JBL woofer has jbl logo anywhere.

You can check it with multimeter like I said earlier. But why don’t you just bring it to the shop and have them fix it by installing correct speakers and wiring harness?

 

the jbl woofer has red surround, no markings visible to indicate its jbl. the base woofer has no red on it. the cross over for the base tweeter is just a capacitor soldered on to the tweeter. make sure to wire the tweeter and woofer in parallel in a base system and it will work as intended.

valde, that body shop is full of idiots that have already refused to fix their mistakes. if they did work on it more, what else do you suppose they will break? perhaps finns are all decent honorable people, but America is full of useless, worthless scum that won't do anything except the barest minimum to get by. if they screw anything up, and you try to make them fix it, they'll only make it worse. they don't care and the law is on their side.

best solution, and as we say in usa "if you want anything done right, you have to do it yourself". unfortunately, this is sad but true.
