Re: Deck is powering off every 5 seconds

If radio stays on at low or no volume and cuts out when turning up you may have your battery backup voltage (yellow wire) droping below 10v under signal load. There is a circuit called backup check in radio that moniters Voltage It may seem ok when measuring without volume but under load it will fluctuate with the audio. Try hooking up Heavy guage Ground and Backup battery wires to prevent voltage loss across wires under load. Also check for any speaker that may not be producing proper sound when and if you can get radio working Disconnect wires to that speaker to see if radio will stay on. Just a couple of many possibilities.

Deck turns off when i hit a bump in my car

A couple things...but the deck must come out to check. (assuming this is a 12v N.American car) If you cannot remove or you dont know how - take it to a car stero shop. Electrical fires are nasty!
  1. Make sure there are no open wires and connections are tight and taped (badly crimped connectors will hide loose connections)
  2. Make sure the deck is supported in the back-it should not wiggle around.
  3. There should be a wire firmly connected to the chassis of the car and the back chassis of the deck - Please do not drill into the deck - use an existing bolt !

sorry about the delay I was on holiday, if you haven't solved the problem yet I would suggest that you check that you are getting both power supplies (red and yellow) and if not the first thing to do is check the fuses in the car. Let me know if your'e still having problems.

make sure the speaker grounds are connected to the speaker ground wires on the deck and not the "chassis" ground. also make sure both power wires are hooked up to a power source. the thinner power wire is supposed to be a switched source (like the ignition key or an accessory switch) that turns the unit on and the thicker one is a constant source which actually powers the deck once the switched source is turned on.

Error message "INTERUPED"

Check the pink wire at the back of the deck. It shouldn't be connected to anything, and you need to make sure it isn't pinched or shorted. "INTERUPED" means that the deck thinks that it's connected to a hands-free kit for a wireless phone, and that you're receiving a call. The pink wire is the interface wire for that type of system.
