Ive had this amp for about 3 months. which connects to my kenwood sub. the other day, the red light on the amp came on (protection mode) and i have no idea why, or how to fix it. I looked at it and the 12v cable was very loose, so i re-connected that and protection light is still on PLEASE help!!!

Re: DUB 2502 Protection Mode help
The most common reason for an amp to go into or remain in protect mode is shorted output transistors. To eliminate other possible causes, read through the following page. Let me know if you have any other questions.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi, the amp is going into protect mode. You can either keep it turned down or possibly reconfigure the speaker connections for a higher impedance. If you tell be the model of your sub, I may be able to suggest a better arrangement.
There is a manual here if you don't have one: http://manual.kenwood.com/en_contents/attachDownload/6017/
when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.
might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.
this is usually a problem with incorrect cabling you should check and see that all your cables are connected properly especially the ground cable thats what would normally give you a red light on your amp
Nope it's not a high-to-low level converter problem, it's most likely a problem with one of two things. 1) either you've blown the output stage in the amplifier, or 2) you've hooked up your subs wrong and your amp is seeing to low of an impedance. The amp is supposed to be 1ohm stable, but we had the same problem. When the indicator light goes red it means that the amp has gone into protection mode, now you have to figure out why. If something in the amp goes bad or just disconnects from the board it will cause power protection mode. If you fry something on the board because you are running the amp to hard or at the wrong impedance it will go into thermal protection mode, however there's no simple way to figure out which has happened.
Have you tried hooking up some different subs to see if the problem remains? try this. If the problem no longer happens then you know it's your subs, if it does still happen then you'll know it's an internal problem.
Years ago I had a Kenwood KAC-821; long story short, I melted the main power wire right off of the board, everytime I turned the system up the amp would shut down.
Take you amp to an authorized dealer and have them bench test it for you.
You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more
The red light means the amp is in protection mode. A few things can cause protection mode.....
First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs.
Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood.
hope this helps
