Home Theater Wiring issues

I just moved into a house pre-wired for sound. I hooked up my home theater system and the R&L front speakers and center speaker all work fine but the R&L rear speakers have no sound. I double checked and all connections are correct. Any ideas how I can troubleshoot this without ripping up the ceiling? I don't know much about home wiring.

Welcome to the forums.

Switch the outputs - do you have sound at the rear and not the front or vice-versa?

This should rule in/out the amp and speakers/wiring.

I'll switch the outputs tonight and reply back. If there's still no sound after switching the outputs, do I need to have someone come in to rewire the house?

Do you have a meter of some sort that you can measure the resistance or continuity of the two pairs of wires?

What kind of receiver are you using? Is the receiver programmed to use rear speakers?

Are the rear speakers recessed in the wall/ceiling or are they surface mounted?

Could the two speakers be bad? If you can measure the resistance across the wires connected to the back of your receiver that go to the two speakers you should expect to measure anywhere from 4ohms to 45 ohms. If the previous owner left their speakers and you are using them, it's possible that they had a HTIB (Home theater in a box) type system.... many times the speakers that come with these HTIB system are proprietary and cannot be used with a standard surround sound receiver. They can measure up to 45 ohms as compared to a 4 or 8 ohm speaker used for a standard surround sound receiver.

Give us some greater detail about your system .... make model numbers etc.

Jimmiee...... remember......keep it simple.

Let the OP switch the speaker wiring first. That will tells us which way to proceed.
