Noise on rear speakers

The bump may have broken or disconnected speaker wires.

The fact that your speakers have only one wire, indicates that they are the old negative ground type. You will have to buy new speakers, or try and connect the negative wires of your speaker wires from the radio to the car body (chassis) and try that. Normally you will get a bit of static when you start your engine

considering that all the wires are hooked up right ,the HU is perfectly ok ,check whether the "Fader"is selected to the front speakers .

hook your front speaker wires up to the A side and on the front of it make sure only the A speakers are playing but leave the rear speakers plugged into the B side then hit the listen mode button and you should be rocking

The infrared mentioned by the manual is most likely an extension possibility to use the remote control in each room, forget that part.
What you need to do is quite simpel, after connecting all speakers, you should indicate in the setup menu of each zone which speakers are connected and do as follows:
in main room select 5.1 setup, for the other zone select only the left and right front speakers.
Your EXTRA SP indicates the extra speakers for 7.1 setup and when set to zone B it recognises only 1 speaker.

So read carefully the manual how to connect Zone 2 speakers and connect that way, than carefully walk through the setup menu to setup the zone 2 correctly.

You need to attach the blue wire on the stereo harness to the blue and white wire on the car adapter harness. they installed a small amplifier to power the rear door speakers and unless you connect those two wires then the speakers will not work.

Sir,
I do not want to insult you in any way, but I must ask just in case it was overlooked! First check to be sure that the speaker settings on the stereo were not set all the way to the front. If that is not the problem, you can hook another speaker you know works to the wireing to the rear speakers to check to see if it is the speaker or the wireing. If you hear sound from the speaker you know works, then your speakers in the car are bad. If you do not hear sound, then it will be from the wireing. Next is the more difficult part. You will have to pull the stereo out and can splice into the wires. Hook the good speakers up to the splice and check for sound. make sure you know for sure the wires you splice into are for the rear speakers. If you still hear no sound, then it is more then likely a problem in the stereo itself. If you do hear sound then there is a problem in the wireing somewhere and may be easier to just run new wires to the rear speakers.

Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

THE 4 WIRES SHOULD BE FROM THE REAR SPEAKERS THEY GET WIRED INTO THE SURROUND SPEAKER OUT POSTS ON YOUR AMP (MAKE SURE YOU DO NOT GO INTO SURROUND BACK THIS IS FOR 6.1 AND 7.1 SYSTEMS).WHAT ARE THE WALL UNITS? NEED MORE INFO TO TRY TO HELP.

HOPE THIS HELPED A BIT.

Set it at 7.1 and just take the rear speakers in the other room with enough speaker wire 16G preferred and set your AUDIO out put to 7.1 all channel stereo only catch is that you won't be able to get a good sound in the second room in any other audio format good luck my friend
