    I have the exxact same problem...for like 2 minutes, it would only output bass if it was more than 50% volume. I ordered a new HIGH to Low converter...maybe thats it?

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.

Let me know what you find out.

No power to amp.....all wire connected properly


is protection light coming on when sub is connected? some radios have weak remote that blow out easy..check power on it if power is making it to amp..if its an ANL fuse they can look good but be bad.

Protect Mode


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
