So I'm pretty sure my Honda civic coupe 2002 only has speakers in the back but my problem is whenever I turn the volume higher than 29 the speakers don't work anymore and you don't hear any music no more, to get it working again I gotta turn down the volume less than 30 and turn off the stereo and turn it back on, I checked if it was a fuse problem and everything is fine the cables are well conecte too

 

Factory or aftermarket radio? Factory or aftermarket speakers?

 

I have no idea what speakers are in this car but I do know the guy had subwoofees before amplifier and bass box before since there's all the cables for it... I have a pioneer stereo tho, what do you think I could do to fix this ? You think the speakers might be bad?

 

Need to find out what you have before being able to figure out what's wrong

 

How do I check what I have? Is there any tutorial on how to take it apart in this forum?

 

See appropriate section for your car above and/or purchase a FACTORY service manual, not one from an auto parts store for the REAL information you seek. You can also search various sites that sell car audio, like the one in Charlottesville, VA that has been around since the mid 70's. they will have info on your vehicle. All you have to do is search.
