Have changed headunit and also speakers..but still got my problem..plays ok till i up the volume then the headunit reboots by itself ... help please


Check the DC voltage at the Yellow and red wire to see whether it falls down when you raise the volume. If you have no meter to check, then buy a battery tester from auto parts shop. If the voltage falls down with volume, check the fuse or contacts in the fuse box.

Hello! Maybe I can help with your question. This model headunit does not support ipod control. It does not have rear or front inputs via 1/8mm jack that you could use the headphone output. You only have a couple of options here. First would be to purchase a wireless fm modulator that would transmit the ipod output through your cars antenna. (i.e. set the radio to 88.1, 88.3, etc) These can be purchased at Radio Shack, Wal-Mart, etc. The only other option would be to replace the headunit with a compatable unit. We sell a Kenwood for $139 that has a front USB port as well as the aux input. The USB on this unit reads droid phones and ipod. That model number is KDC-248U. Hope this helped! Good luck with your venture!

I have two ten inch subwoofers hook to my clarion cz200 they work with the tuner but not when listing to aux or usb how do i fix it


Sounds like you have the amplifier for the subwoofer only coming on with the radio. On the back of the Clarion radio, you should have another blue wire, but with a white stripe. This is the correct wire to use for turning on the amplifier. Connect this to the "remote" or "turn on" connector of the amp.

Buy a rca to aux 3mm plug then you can connect to aux port.
RCA out is for the signal to the amp from the Head Unit. Mic is probably for your cell phone.
Am pretty surprise that an HU like that doesn't have USB Ipod support?

How to wire a sony cdx-gt640ui in a 1999 dodge intrepid...I get sound with the tuner, but no sound with cd, aux, and usb. I'm assuming its only an incorrect wiring setup...


instead of used the blue wire on the Sony head unit to the car wiring harness use the blue/whit wire

  • Blue - powers on only when am/fm is active
  • Blue/White - powers on when when radio is on am/fm/cd/ ect.

Subwoofer in my car works only on tuner


I had the same problem. most radios have a power antenna wire and an amp turn on wire it sounds like your amps are being turned on by the power ant wire that loses power when you put a cd in try swapping the blue with blue and white wire this should solve it
