So the other day I took out my subwoofer in my car. now the front speakers don't work when the rears do. I checked all the wiring and theres no problem. Before i took out the subwoofers, both front and rear worked fine.
Any ideas?

 

put it back in to see if it fixes it

 

are u sure all the grounds are hooked up good and did u make sure to tape off ur remote wire ?

 

If f possible try to hook up speakers to the leads immediately out of the head unit. Rule out wire without having to get into the doors. It may be a bad head unit. I had one that just decided it only wanted to drive the left rear and the sub.

 

Check the HUs fader position. 94

 

True

It can be the smallest/most obvious things sometimes I've many a time missed a lose wire hidden or just something that is so obvious you'd never think to check it lol

 

Like when a girlfriend calls cuz her car won't start and you get there to fix it and its because its in drive. ( true story )

 

Happens more then you think, without more info from OP, my second guess would be, there is a 4ch amp, fronts on two channels, the other two channels bridged "mixed mono" for the sub, the rear speakers are off the HUs internal amp 4ch amp, [rear channels].

The off board 4ch amp is not working, either damaged or off.

Third guess, both front speakers are blown.

I would assume OP has checked all the obvious possibilities.

OP said, "I checked all the wiring and theres no problem" that is kind of vague, and he may have checked all the wiring, but there is definatly a problem.

Without more info, that's all I got. 94
