Rear speakers dont play with connection box

My head unit works fine and when im listening to the radio the rear speakers and sub work fine, but when i plug my mp3 player into the connection box it stops playing from the rear and just plays out the front door speakers. Im not sure if its because its not compatible with an mp3 player or if it would work if i connected a dvd changer. any help would be greatly appreciated, thankyou.

I believe this is a wiring incompatibility problem. The reason I say this is because when the mp3 player is out the jack which contains switches engages the front L&R and the Rear L&R, when the plug is inserted into the jack the jack switches should remove the audio input to the amplifier and replace it with the audio from the mp3 player. The switches should then send sound to the front L&R and the Rear L&R but the only change should be that the mp3 player is switched in instead of the audio from the raido unit. what is happening is that the jack switches are only switching in the front L&R speakers. This just might be a function of the unit. check the owners manual. here is a site that has the manual:

When playing cds in my sony cdxgt500 the sounds come throught the door and rear speakers fine, but not through the subs. everything works as it should while playing the radio.

Hello.... it sounds like you have the remote wire for the amplifier hooked to the solid blue wire behind the radio. You need to hook to the blue/white wire behind the radio. What happens is that the solid blue wire turns on the power antenna when you are listening to the radio and it turns off (lets the antenna down) when you listen to a cd. There should be a blue/white wire that is the amplifier turn on wire that will stay on as long as the head unit is on. Hope this helped!

Kenwood eXcelon radio problem I have 2 subs in my civic that work perfectly fine but i recently tried to add another amp to run my front door speakers seperately. I spliced the remote wire between the two...

Cut the remote wire from the radio.
install a relay in line
the relay will have 4 or 5 terminals
connect terminal 87 to battery power and fuse it at 3amps
connect terminal 86 to the remote output from the head unit
connect terminal 85 to ground
connect terminal 30 to your amp turn on wires
this allows the turn on load to run thru the relay and not directly off the radio remote output

Connecting an MP3 player to car radio

The most common way is to use the auxiliary input of the deck or head unit. However I don't believe the JVC model you have has one of these. Don't despair though. Head to your local department store with a music department and pick up a universal FM modulator ($20-$30).

These will 'pretend' to be an FM radio station inside your vehicle. Attach the stereo mini plug to your walkman or other audio device (mp3 player etc.) Then tune the FM Radio to the fm station listed on the FM modulator and you will be able to listen to the device through your car stereo speakers. Now this isn't as clean as a direct hookup but for most its an economical way to listen to alternate sources on your Car Stereo.

Can't fit subwoofer amp leads to pioneer DEH-2000MP Head unit

pioneer head units only distribute like 200 rms or so to the speakers. you might have to find a blue maybe even blue with white striped wire and nick it just enough to tie your amp wire around it. tape it up and see if it works.

Please check your model number, I can not find it on the JVC service website.

This is a powered sub-woofer I think. You need to have a thick black cord that connects the sub to the head unit. Then the satellite speakers get connected to the speaker jacks on the sub-woofer box. The sub-woofer should also be plugged into an A/C outlet on the wall.

The speaker outputs are labeled right there where you connect the speaker wires. You should see a red and black connector for each speaker and they are labeled "front right" "front left" "center" "rear right" "rear left".

If you do not have the thick black cord you need to connect the head unit with the sub-woofer, you can not use this system.

If you look at the head unit and give me the model number on it, I may be able to find the part you need. But I must have a good model number to work with, preferably from the head unit.

Samsung yp k5j radio doesnt work

You have to plug in the headphones. The head phones act as an antennae, therefore you need to be plugged in. YOu can still listen through the speakers, but keep the head phones plugged in.
