Question about Kenwood KAC9105D Car Amp

1 Answer

Kenwood kac-9105D amp

The blue light stays on but not the red one. I have every wire hooked up and I'm only running a 500w rms alpine type S. I ran for about a day and today I went to start my car and ready to listen to some bass but no bass. Any help would be appreciated.

SOURCE: adjusting wattage on kenwood kac 9103 class D mono amp

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

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!

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.

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 fromhttp://www.kenwoodusa.com/Car_Entertainment/Amplifiers/KAC-9105D

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.http://books57.net/ampOuts.gif

Any help?

Power control wire - tells the amp to turn on, usually connected to the blue/white or blue wire when blue/white is not present on aftermarket radios. On factory systems you usually want to hook up this connector to an acc source on the car

Red Light


that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad
