Hi. I've got Kenwood KAC-704EX and when the system turns on, there is a blinking red triangle and unit doesn't work. What should I check or do, please?

The first thing you must do is to confirm that you have voltage at the amp. Just because the fuses look good, that doesn't mean you're getting power to the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

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.

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.

from your sub connect one short piece of cable from + on one side to - on the other side using the same diameter cable as you are running to the sub from amp . this will leave you with + and - on opposite sides of speaker these will then run to the amp +to+ and - to- on the mono side of connetor which is one left + and one - right and the amp switched to bridged

maybe when hook up something sorted and blew the sub side .I have seen it happen
