Hello, can someone help me, i want to know how to connect the wires if i want to use 2 channel instead of 4. THANKS IN ADVANCE!!!!!!!!!!!!!


You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:
http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

How many watts is it

Page 7 of the manual gives you all the different configurations of this amp, and it's MAX power. FYI; Kenwood rates their amps at MAX power, not clean. Hope this helps.

Front right speaker got wet, started cutting out. at the same time the rear right speaker started cutting. switched the rear speakers to opposite channels and this caused the right to work and left to cut....


the speaker getting wet will short it out. Shorting the output on any amp will ruin it. there is a right and left chanel with 2 outputs. Right chanel is damaged.

The subs aren't pushing out bass.


Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

Kenwood kac9152d bridge mono wiring diagram


only using one of the channels for audio and having the rest of the amp wired up as normal should work fine. for example just use the right channel and leave the left unwired.

Shorted a RH front speaker, now there is no output from RH channels at all


The output stage of the amplifier (RH channel) was probabla damaged from the grounded cable. The heat in the speaker means that the coil (d^speaker) is recieveng DC power from the damaged amplifier. Audio amplifiers are not special and can be fixed. In many cases, the output stage is a power MOSFET or a power audio amp IC. The only issue is the availability of the parts in your area.
