  If you see 'PAIRING FAILED' on your Dual Car Receiver's display, it could be due to several reasons: 1. The pairing attempt might have exceeded 60 seconds. Retry the pairing sequence, ensuring it completes within 60 seconds. 2. Your phone might not be set up correctly to connect to a Bluetooth hands-free device. Check your phone's owner's manual for instructions on enabling Bluetooth. 3. The Bluetooth device might not be compatible. Contact technical support for more information.

  If your Dual Car Receiver isn't powering on, several factors could be at play. First, the yellow wire might not be correctly connected or may have an incorrect voltage. Ensure it's properly connected and has a voltage between 11 and 16VDC. Second, the black wire might not be connected to ground, so verify that connection. Lastly, the fuse might be blown, in which case you should replace it.

What to do if my Dual XDMA6855 has power but no sound?

  If your Dual Car Receiver has power but isn't producing any sound, the issue likely lies with the speaker connections. Check the speaker wires at the speakers to ensure they are properly connected. Also, verify that none of the bare speaker wires are touching each other or the chassis ground. If they are, insulate them to prevent contact.

Why does my Dual Car Receiver keep blowing fuses?

  Edward SalasAug 26, 2025
  If your Dual Car Receiver is blowing fuses, there are a few potential causes. The yellow or red wire might be touching the chassis ground, so inspect them for any pinched areas. Similarly, speaker wires touching the chassis ground could also be the culprit; check those for pinches as well. Finally, the fuse itself might have an incorrect rating, so make sure you're using a fuse with the correct rating.

  Jeffrey WilsonAug 27, 2025
  Excessive skipping on your Dual Car Receiver can be due to a couple of reasons. First, the unit might not be mounted correctly, or the backstrap isn't secure. Check the mounting sleeve and backstrap support to ensure they are properly installed. Second, the media itself (CD, CD-R, or CD-RW) might have a physical defect, so inspect it for scratches.
