Re: kenwood kac-848

You have blown outputs , faulty channels. What kind of amp do u have and what were u running to it? Most likely a bad amp, u might need a new one.

How to bridge a kenwood kac-9105d

Are you referring to something like this, using two different amps? It is a mono amp, meaning there's one amp in the box.
"KAC-9105D also has a Dual Mono Drive connection that allows you to strap two KAC-9105D amps together to power a single subwoofer."Quoted from

Here's a link to a page out of the Yamaha Sound Reinforcement book. the top shows a stereo amp (1 box, two different amps inside) hooked up to drive two different speakers, which is known as 'stereo' mode.It then shows the two amps hooked to the opposite sides of the same speaker, which is known as 'bridge' mode.

Any help?

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.

I have a kenwood kac-8452 4 channel amp that makes the speakers pulse after the volume gets turned up to 10. I also have a kenwood amp doing the same thing with my subs. any ideas?

Its not pulsing, its called clipping. The sound is being clipped due the amp being pushed past is power capacity and distorting the signal. This will damage your speakers very quickly. No amp should be turned more then 3/4 up. If its not loud enough you need to purchase a larger amp or be comfortable with the wattage it produces at 3/4 volume. You may also have speaker wires touching/crossed causing th issue.

There is an Internal Fuse on Most of these Models that will blow from time to time. You might also check the Ground Connection. A loose Ground can cause the Same Problem. Please Rate My Response! Thanks!

Kenwood KAC-848 amp not working

It sounds like the amplifier is going into protection mode. This is generally due to shorted output transistors but can also be caused by shorted wiring. Disconnect all of the speaker wires and signal cables from the amp. If it still does the same thing, confirm that you have adequate voltage across the B+ and ground terminals (at least 11 volts DC). If the votlage acrosss the terminals is OK and the light still flashes with no speakers connected to it, the amplifier is in need of repair.
