Very possible that you have a blown power supply in the amp. If you are running a mono amp then there is a very good chance that you have loaded your amp with too low of a speaker impedence and fried the power supply and maybe the output section of the audio area. Hope this helps.

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?

I need to know the wattege of a kenwood kac -624
The KAC-624 is a 40 watt x2 @ 4 ohm RMS amp. 55 watt x2 @ 2ohm. 110 watt x 1 Bridged I assume at 4 ohm. Manual does not specify. It can run 2 ohm in stereo mode but is unclear on mono impedance requirement. It can run 4 ohm mono at 110 watt but at 2 ohm?

My kenwood KAC-7204--- the wiring is hooked up right, I just got a 2000 watt max sub 1000 watt rms, i was running the amp in bridge mode and it ran for 1 day than it turned off. I checked it and the fuse...
when i was running my sub off bridge mode this kept happening to me. I ended up just running two subs and for some reason the fuse stopped blowing. i think there is something wrong with these amps.

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.

Cant get but one side to work
This amp (kenwood  819)  was designed for use with a sub-woofer, hence the single chanel. It will however power up 4 speakers in mono, and if they are capable of handling the amps.while robbing you of the benefits of stereo as well as left, right and fade control.Good luck...
If you still want it connected. You should purchase an amp installation kit, and review the topics and videos at this web site. www.installdr.com

 Good luck...

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.

Is it not bridgable
This amp isn't bridgeable. It's a mono amp (only one channel). You need two independent channels to bridge. Some mono amps are bridgeable if you have two identical amps but I don't think Kenwood recommends that with this amp.

Kac-8152d
Are you sure you are getting signal to the amp. Try another signal source. try temporarily connecting the shield of the input cable to the car body ground. The signal ground may be open in the head unit due to a previusy faulty amp.Most newer head units ave tis signal ground fused inside the head unit.Older ones ma have bunt circuit trace. If it works when you groud the input to the car body this is what has happend. The previous amp had an open power ground so the curent when to use the signal ground but it will not hold the curent so it in turn opened.
