Question regarding two speakers that should sound the same but don't.

Hi, I'm having a problem with the two full range speakers that are installed in the rear of my Honda Accord. The rear right speaker now sounds perfect and is working just as it should, however the rear left speaker is much more quiet and is not producing and low frequency sounds. I checked the wiring 10 times over and everything is fine as far as I can tell. It's not the balance setting on the head unit, I made sure it was in the middle. Has anyone ever had this problem and know how to fix it? Any help at all would be greatly appreciated.

Did you try switching the wires at the speakers from one speaker to the other and see if the problem moves with the wires?

Is yes, then it's not the speakers.

Next would be to again move the speaker wires, but upstream, say at the source, and see if the problem moves, etc.

hey man thanks for the quick reply. but i did what you said and it's not the speakers. i've tried every single configuration and it is always that back left that is really weak.

what do you think could cause something like this?

thanks man

Maybe there is something physically wrong. Can you take the speaker out to manually check it for physical damage? Maybe the cone is cracked, or the cone came into contact with water. Try powering the speakers from a different amplifer if you can and see if the problem persists.

Assuming the speaker once worked, and then one day didn't, my guess would be a voice coil problem, either from too much heat and/or over excursion (lots of loud play time, distortion from too much amp gain, could be lots of causes).

If it's a new set and it never worked, it could be the voice coil is binding (might work itself out of this?), or if it's a multi-speaker arrangement (like a 6X9 with a smaller speaker(s) in the middle), it could be the connection and/or internal crossover.

Either way, it certainly seems like the speaker is bad.

EDIT: DodgeCummins (below) has corrected my inability to read and understand. There is a possibility that the wires to the speaker have rubbed through a bit of insulation. I would think the next thing to test is to run aother set of wires to the speaker from the head unit/amp. No need to hide them, it's just a test case.

BTW, is this an OEM head unit w/o external amp (if yes, then it would eliminate corroded or bad connections on the RCA plugs). If you are using RCA cables, I had a bad connector on a Memphis 30-channel grapphic equalizer that caused low volume on one channel. What I'm saying here is to check any electrical connection - especially in any area that has either been recently worked on, or is subject to the errant foot kicking the wires.
