If disconnecting all power wires, and replacing all fuses (including inline ones) doesnt reset it. then its toast. Hate to break it to you :( Contact the manufacturer if you feel it is under warranty.

2 things could shut your amp...to low of a ohm load, or very low voltage drops. I need some more info to help you out.
1. Is the amp really hot when it shuts off?
2. Is it a mono sub amp or 2 channel stereo amp?
3.What ohm's are your subs & are they SVC or DVC?
4. How do you have them wired to the amp?
You can email me at thefowlerfam09@yahoo.com I have a idea whats going on just need some more info.

Red lights and error codes usually mean a fault ha occurred. Usually blown output transistors or input power supply caps are to blame. Don't try to fix unless you are comfortable with doing that and have the equipment. Also try emailing Kenwood tech support, they will be happy to tell you exactly what the error code is and possibly why it is happening.

Hello mogly20,

The amp probably won't know if it's you or the homeless guy, so try smashing a glass bottle on it like he did. If that doesn't work, I'd recommend you locate another homeless guy and buy another amp.

Hope this helps.

wireing an amp can be tough it starts from the e.q.the e.q. must have a sub out.

I do believe this is caused by one of your amp fuses. Depending on which + on the amp is being used. That channel has a blown fuse. have you tried running + and -, + and - to both channels to see if both subs worked? If one sub doesn't then it's a blown fuse or scarred fuse and needs to be changed.

According to page 7 of the radio's manual, E-02 means the amp has failed and DC is being applied to the speakers. It also says "Turn the POWER switch "OFF" and release the protection."

you probably blew it up. Whenever you smell that smell it is almost always a capacitor in there that blew.

Page 13 says it is activated by the user. It tells you to treasure the code. Ask the last user. Take it to a Kenwood Service centre. Try a reset as shown on Page 3 of the manual.

Any video file that is .avi requires codecs. Most players don't have a comprehensive list of codecs on their chips though they have divx and xvid on many devices these days. divx and xvid are codec types of .avi. Types such as .mpg or .mpeg or mp3 or mp4 are older and more compatible with most equipment. mkv may not work
