Amp problem ok so i initially touched two wires together and of course the amp shut off and i let the amp sit reset itself for a coulpe of hours and it worked again but once i got the wires hooked up i started to turn up the radio and the amp cut out and wont turn back on,  i turned off the car and then turned it back on and the jenson light on the amp was on (very dim), but the power light for the amp was off and the stand-by light wasnt even on so whats the diagnosis for my amp doc? did i just loose my amp or what?

Check connections/wiring before ditching the amp. May just have gotten a loose or bad connection, or may have a short-out somewhere that got disturbed if you were driving it, or tucking wires away.

Make sure the amp is well ventilated, it needs to cool down or else it will shut itself off, then when it has cooled off enough it will turn on again. Also, check your wires especially your power wires. Make sure that they are the correct gauge. If everything looks ok then there may be a fault in the amp.

I have a 2005 town and country and code# P2097 just came out what this code mean


your post cat O2 sensor is reading too rich... try this, completely disconnect the battery, touch the wires together with a wrench for one minute, (THE BATTERY CABLES, NOT THE BATTERY!!!)

leave the battery disconnected for 30 minutes to one hour, hook the battery back up, start the vehicle, don't touch the throttle, brake or anything else for 5 minutes (if you have a garage don't forget to open the door)

turn off the vehicle and restart it, if the code doesn't clear itself then take it to an auto parts store, tell them you think you fixed the issue and need the code reset so you can be sure.

if the above steps don't work then you will need to take it to a dealer as there is some other reprogramming that they are able to do.

here are the steps they should follow, notice none of them include replacing an O2 sensor

they should check/clear the code.
reset the adaptation values.
do a "quick delete" before disconnecting communication between diagnostic equipment and car.
disconnect the battery from the car.
do a battery reset- touch both connectors that go to the battery posts with with a wrench for a minute.
let battery sit disconnected for 1/2 hour.
reconnect battery.
check to see if code is gone.

good luck

Your amp could be in protection mode! Sometimes turning up to high or wires touching will put in protection mode! It will have to be unplugged for a day or two to drain all power out of the memory. Leave accessorie/ignition wire hooked up, just not power and ground wiring. It should reset itself.

Mistub XD450. Bulb relatively new. Projector


Does the projector work normally when sitting right-side up? If yes, something could be interfering when the unit is inverted. The symptom you describe initially sounds like a defective fan (some fans put out a computer pulse telling the main board it's running--they have 3 wires, red, black, yellow(signal)). If the board doesn't get signals from all required components, it's programmed to shut down to protect itself.
