Mazda 3 2007 left side speakers not working.
 

Hi all
I have a mazda 3 2007 and the left side of the cars speakers stopped working a few months ago sometimes when the car gets hot or the engine they will work again. I have today spent a fortune on upgrading the head unit etc but still the same problem. I have been told it could be the in car amp but where is it?? I have checked under both front seats and nothing there. I have been told off a possible Bose amp but I don't think its the Bose system as nothing is labelled with Bose . I'm at my wits end and really could do with some help.

Have you tested the speaker wiring & the speakers themselves?

I have had someone look at it and they told me it's not the speakers or the wiring possibly the built in amp , thing is when I Google where the amp is it says under passenger seat but there is nothing there? Have read that some mazda 3 have little amps inside the door but I ain't no car expert so don't want to rip panels off. Maybe I take it to mazda garage.

If there are no "Bose" logo's on the head unit or door cards, then you don't have the bose system & there-for no amplifier.

You need someone with audio experience to test the speakers & wiring.

Awesome thanks for your help much appreciated.
