Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

I have 3 Kenwood 12'inch subwoofers need to know how to wire them up to a Kenwood KAC-9105D


Follow the link and use the first diagram which illustrates wiring the subs to 2.66 ohms http://www.the12volt.com/caraudio/woofer_configurations.asp~Q~3~I~42

Remember that that amp is one ohm stable so you will not be getting the most out of that amp with that subs set up. The subs will only see 650 to 850 watts total...so each sub will only see about 215 - 275 watts a piece. Find out what the RMS wattage of your subs are each an determine if the wattage I mentioned above meets those requirements.

My kenwood KAC-7204--- the wiring is hooked up right, I just got a 2000 watt max sub 1000 watt rms, i was running the amp in bridge mode and it ran for 1 day than it turned off. I checked it and the fuse...


when i was running my sub off bridge mode this kept happening to me. I ended up just running two subs and for some reason the fuse stopped blowing. i think there is something wrong with these amps.

Can i run just 2 subs on this 1200 watt kenwood 5-4-3 and if so what way will i get the most power, i mean do i bridge it or pute the speaker wires in other ports


you can run 2 subs given that you dont go over 2 ohms of resistance and that the subs are rated at 1000 watt max each around 4 or 500 watt rms. if your not sure about ohms dont bridge it and get single voice coil subs. this amp is capable of about 700watts constant power 1200 max spike if the voltage stays at 12 or higher.

It should be better to use the Pioneer GM-7200M Amp with your subs.

For 8 ohm setup hook up this way:
Amp out+ to Sub1 +
Sub1 - to Sub 2 +
Amp out - to Sub2 -

For 2 ohm setup hook up this way:
Amp + to Sub1 +
Sub1 + to Sub2 +
Amp - to Sub1 -
Sub1 - to Sub2 -

KAC-8401 Shuts off Blue light still lit


HI RLF,

You might want to turn your Gain setting down a little. Also Look to be sure you have enough air flow around the amp. If it cannot breath, the heat from the amp will build until it wigs out. Use your Ingenuity to get more air to the AMp.
