Okay, so I recently installed a full stereo system in my 96 Bronco (as a former import tuner, I still need a good sounding stereo system, sorry). For some reason, my rear driver's side speaker is really quiet. It's playing, but it's maybe 1/4 as loud as the other speakers. I was told by my local shop that it's probably a ground, but I can't get it in there until Friday. I was wanting to get it fixed ASAP so I can finish setting up my system. Can anyone tell me where the ground is for this speaker, or what else the problem might be? And by way, yes, I checked the speaker. I tried 2 brand new speakers in there, too, and got the same result, and they all work find on the other side. Thanks!
