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.

SOURCE: KAC-7202 will not put out sound. Put in other amp works.

When you switch on the amp did the main amp ic produce heat. If does not change the main amp ic.

SOURCE: To bridge a Kenwood KAC-9102D

Hello laurogleal,

The Kenwood KAC-9102D is a mono amp. There is no bridging. Having two sets of terminals is just a more convenient way of connecting two subwoofers. The amp is stable down to 2 ohms impedance, so it is safe to run 2 4 ohm loads in parallel.

Hope this helps.

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

How do I wire two subs up for the full 850 rms on a kac-9102d amp



  • Wire up two 4 Ohm subs in parallel (bridged) or one 2 Ohm sub.

  • You will take both of your subs positive leads and run them to the left positive (white connector on the amp) and both of your subs negative leads and run them both to the right negative (gray and black connector on the amp). That's max RMS right there. Pay attention to the Ohm rating of your subs as this does play a factor. What I explained is how to bridge two 4 Ohm subs. 8 Ohm is a little different but car subs rarely are 8 Ohm.

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.

Just woundering if i could bridge one sub to front and one to rear the subs are kenwood w3514 dvc subs the amp is kenwood kac-x501f


Hello bigmac208,

Yes, that would be the best connection for both the subs and the amp.

I'd wire the sub voice coils in series since the amp will not be stable at 2 ohms when the channels are bridged. The power will be somewhere between 100-200 watts RMS to each sub. While it's not pavement pounding, it should provide pretty good bass, especially if you tweak the crossover and boost settings for best bass response.

Hope this helps.

Want to bridge my subs I have a kenwood kac-719


from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

How too hook my kac 7201 up to my two dual 4 ohm Alpine type Rs


Hello manbearpig65,

Well, that's a 2-channel amp, so it's really best used to power a set of regular speakers.

The best power solution, for your existing components, is to wire each of your subs voice coils in parallel, resulting in a 2 ohm load, and then run each sub off a separate channel from the amp.

The amp is stable only to 4 ohms in bridged mode, so you would series the sub voice coils (8 ohm load) and then parallel them (4 ohm load) to the amp bridged connection. This will result in less power to each sub than if you ran them separately.

Hope this helps.

Kenwood kac-7202 wirng 4 subs


look at the Z [impedance] specs for the amp. Look at the Z for the speakers. You may eventually have to wire them in a series-parallel config or risk blowing your output transistors.

Due to the utilization of so many drivers, your power demands are limited. The more drivers you utilize, the more volume loss. Bass response requires a lot of power (W) in which to drive.

Do not worry about paper or polyprop/carbonate structures... focus on your impedance issue or risk frying the output transistors in the long run [thermal runaway].

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?
