Question about Kenwood KAC9105D Car Amp

1 Answer

I have a Kenwood KAC-9105D amp. It is brand new and worked for about 20 minutes while I was driving and it hasn't worked since. When I turn my car on, the blue and red LEDs on the amp both come on for a split second and turn back off. I have checked the fuses, re-secured EVERY cable for the amp, checking all the connections. Any ideas? I'm at a loss as to why it isn't working.

First of all, how are your subs wired to the amp. Make sure your amp is not bridged or you'll fry it, it only has one channel. If that doesn't work you probably already fried your amp.

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

It's the battery, not enough juice to supply your amp at loud volumes so the bass will drop out especially on long bass notes. Replace your battery!

What is the p. con on the back of the kenwood 9105d?


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

Amp turns off after about 5-10 minutes of use for a few seconds


One of two things...Amp is going into overload protection (should be indicated by a light on the amp), or you have insufficient power going to the amp....if this is the problem, try a 2 farad capacitor on the input power line to the amp.

How to wire kenwood amp to kicker cvr 12"


How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun
