It sounds like the output transistors have failed. Disconnect all of the speakers from the amp and power it up. If it still goes into protection, an output has almost certainly failed.

 

To repair it yourself, you'd have to find the defective one, purchase the replacement parts and replace the parts in the circuit board. 

 

This type of damage is often caused by driving an ohm load lower than that recommended by the manufacturer.

Typically you may be allowed a 15 minute break in morning and afternoon but usually with a 30 minute lunch. Depends on job and employer. Make a friendly inquiry to HR or your boss. Work flow nay dictate if can take those am and pm breaks.

No Bus 08 dodge avenger..windows,radio,heater...etc..no start..disconnect battery..now its running again


Just bought a 2013 dodge avenger, literally yesterday. Test drove fine twice,, drove all over town for license and registration, multiple erands. No problems. I got to work and went to leave for lunch and was introduced to the no bus code. Left me stranded the very day i purchased it,, only 25000 miles. Is this problem simple enough to weather or is this the brightest red flag to take it back?

Amp Not working!


If the amp goes into protect mode, it's likely due to shorted output transistors. To eliminate other possible problems, read through the following page:

Amp in Protect Mode - Troubleshooting

If the problems are not with the wiring, follow the link at the bottom of the page to the Amplifier Repair Primer page.

Let me know if you have any other questions.
