Red Light


that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad

What does it mean when the power light blinks on the amp?


genrally kenwood amps are power hungry amps so after playing for a while if it doesnt get the amount of amperage to make it work it will shut down cus you car cant charge the battery long enough for the use of that amp so my idea is try a farad capacitor and see if that helps good luck .......tk

If it only does it when bridged, the ohm load may be too low.

Is it blowing the fuse on the amp or the one near the battery?

Amp


Sounds like you have blown 1or2 channels in the amp. The transistors that are against the heatsink. Check all you should find some are gone.

Power of amplifier


If the KAC-7252 is to be bridged, the operation mode switch on the top of the amp is set to mono. When switched to Mono, the signal from the left channel input only is used. Bridging creates 4 times as much power so the KAC-7252 delivers 170 Watts per channel so that 340 watts total so that value 340 is multiplied by 4 and that gives you 1360 watts of power. so it will drive them.

Light stays red


I do belive this amplifer has a red light when it is on... I know my Kenwood does. I suggest checking all your wireing between your amp and your speakers, check the impediance between your positive and negative terminals on your leads to the subs.
