Question about Kenwood KAC-8403 Car Audio Amplifier

My back speakers wont produce any sound

Hi, I installed a kenwood kac-8403 4 channel amp in my car yesterday, with the back speakers on channel B and the front speakers on channel A. For some reason I had the input selector on A instead of AB. When I turned the power off I switched to AB and turned the power back on, but the back speakers didn't play any sound. So I proceeded to turn off the power and switch back to A, then the back speakers had sound but not as loud as the front speakers. Then I switched the setting back to AB but forgot to turn the power off before doing so, I spoke to kenwood support and they told me I need to reset the amp, but I don't know how to do this, and if anyone could explain why the back speakers wouldn't work on AB, that would be great also. Thanks.

OK I believe there is a small indented "Reset Button" around somewhere on the back of the unit, With the unit powered ON, & using a small diameter implement, straightened paper clip etc, press IN the button and this should "Reset" ya unit. This may indeed fix all your problems as the Unit "Reads" the speakers at turn on.

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.

I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

Beeping sound from amp when car headlights turned on

it could be a indication of low amps.

Does it happen when car is running and lights are on?

If car is off do lights dim to the music at night?

You could be using more power than your alternator can supply.

Most alternators are capable of producing 55-65 amps. This is adequate for sound systems producing up to 350 watts RMS. Some more modern vehicles have alternators rated up to about 120 amps. This will be sufficient for systems of up to about 600 watts. Some pre-1985 cars, on the other hand, have alternators only rated for 35 amps. This will only support about 125 watts in amplifier power.

One easy, effective solution maybe installing a capacitor. Heavy-duty capacitors connect to the power cable (just before it reaches your amplifier) and act as a buffer zone between your amp and your car's electrical system. They store up a reservoir of power which can supply the amplifier's peak demands (like a bass drum beat) without having to draw current from the battery.

First, Check your earth is excellent and not all clustered on one point. Ensure power leads are thick and secure. Separate speaker and power cables.

Check auto turn on wire (thin blue on amp) is not connected to lights power source, use elect aerial output on head instead

Run 4 gauge earth wire to car body near amp, power cable must be heavy gauge too, expessally with a sub woofer running.

How to wire kenwood subwoofer to kenwood KAC-8404 car amplifier

Hi, this is a 4 channel amp. Not really designed for a sub, but you can use it that way. Cay you tell me all the speakers you want to hook up--need their sizes or frequency ranges and their impedances. Or, if you have model number for the sub that will do. Is it one sub or 2? I will then get back to you with a recommended setup. OK?

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.

Powering 4 6x9 speakers, need amp

Hi firstof all your deck isnt really putting out 52 watts x4 more like 17-22w rmsx4 ,companies like to throw out some crazy numbers it seems. If your into Kenwood try out a KAC-8404 4-channel on the mids/highs that will put 50 w x4 rms at 4 ohms or if you wanna go a lil louder try the kenwood x600f that will throw 100w rms on each 6x9 at 4 ohms no problem. My system is very similar to yours but running 4 pioneer 5x7's in all the doors and powering it with the 8404 its loud and clean ,fan cooled and no problems at all. My subs are a pair of 15's soundstream t-4's powered by an Alphasonik pma2500a its throwing 800w rms on each sub running in stereo at 2 ohms.It can drown out the mids if i set it that way but my mids /highs cant take as much power as your kenwoods can or else id step up to the x600f too.
