Rear Speakers Aren't Working

[rock883]

Hey guys. I noticed this a while ago. I have a clarion head unit, and a rockford fosgate 75x4 amp running the door speakers. Obviously the amp is getting power because the front is working. I have looked at the rca's on both ends and they are snug. I haven't however,. pulled the door panels off to check the connections. But it is hard to beleive that BOTH rear speaker's connections would go bad or come loose at the same time, you know? I have also checked the connection's on the amp side, so that is not it. I doubt those would come loose anyways, because they are kept in there with a bolt basically. So what I've come up with is that it may be the HU's outputs. I have a 3 or 4 year service plan from best buy and I can send it in to get fixed, but that will be my last resort because it takes them 2 weeks to get it fixed, and I have had to send it out twice already and it really reallly sucks not having a radio in there. But I will be pulling my door panels off more than likely this weekend to put in the b-quiet I ordered, so I will check on the connections, but I highly doubt thats what it is. Thanks for any direction you guys can give me here.

did you try switching the rcas on the amp (front to rear and vice versa). if the front goes out, then it is the headunit. if the fron works and the rear is still out, it could be the amp, connections, or speakers.

that's an easy way to check. i had an amp where the left side wasnt working, and i tested it by switching the right and left rcas.

good luck.

Wow. Thanks for that. I didn't even think of doing that. I will go try it tonight after I get off.

You could also reverse the speaker leads to see if it is the speakers or amp. You can also take a D cell battery and take the speaker leads of the amp and connect the positive speaker wire to the battery and then tap the negative lead to the battery and listen to see if you hear the speaker making a popping sound. If it does you know the wires are connected.
