Question about Kenwood KAC-9103D Car Audio Amplifier

Open Question

My Kenwood KAC-9103D is not getting any power, when I tried it on a seperate set of gauge wires, still no results. My friends Sony Xplode is running fine with on both sets of gauges. So we know it is not the wireing in teh car, and both subs work. The light doesnt power on, the fan doesnt come on, and it is hooked up correctly. The last thing that happened, was my grounding cable, accedently came loose somehow, and then when trying too put it in, it touched the Power wire, and I heard a crack, from then on out it has not worked. I have checked teh fuses, they are fine. Wiring fine. It must be the amp. We looked online and some people say, that our ground connection has come unsoldered. We took apart the amp, and could not find a circuit map, and thus could not locate where anything was unsoldered without the map. We know where the ground connection is, and it looks perfectly fine. Any suggestions?

use a multimeter to check for power on the +ve wire, could be your fuse, it only rus a sec when you jumper the remote to +ve because the remote cannot give out the nessary current to run the amp.

Well, the sad thing is, it can be a number of things. You will have to do a process of elimination. Try replacing the amp first, borrow one off a friend. Second try replacing the subs. If those don't work, read the manual to your deck. Find the audio settings, and check to see if the sub section is "on".

it sounds to me like its burnt.but with some amps the screws that hold it in place have to be screwed into the car chassisfor grounding. be careful not to srewe into hidden wires.

SOURCE: amp light is on but no power to my subs!

Hi There.

When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.

Hope this helps!!

My kenwood kac 9103d just crapped out on me and i am looking to buy a new amp but when i bought my sub the guy specifically wanted to know what type of amp i had to match it to the sub. so now do i have to...


More specifically, the amp must support the resistance of the sub, or subs. If your amp is 2-ohm stable, it can run a sub, or subs wired for a 2-ohm load. Also, whatever the recommended maximum wattage is for the subwoofer, try not to exceed this much, if at all, with the amplifiers wattage.

I want to know how to wire up 3 12' subs to the kac-9103d amp my 12's are 8 ohms


to get the most power to your subs from that particular amp and those 8 ohm coils just wire the coils in parallel and that will give you a 2.66 ohm load. You will be close to the maximum rated rms output power for the amp that way

Why does the kenwood kac-9103d has two sets of terminals if its a one channel amp so how do i hook up a dual 12 phoniex gold 1200 watt sub to it


Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

Kenwood kac-7204 1000w amp with 12 in sub what size wires nedded to use


bigger the better my friend. Look at your Peak RMS output, and how long of wire you need. Then you could make the judgment call on how thick or what gauge you need. (2 involved factors power + distance). id say 10 gauge and you would be fine.

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.

Power from the kenwood 9103D to the Kicker comp 15's is on n off


Most times I hear of people turning up the volume on a head unit and cutting off on the amp it tends to be wired to a speaker with the wrong impedance. I googled kicker comp and got tons of different models, not to mention almost all of them were 250 watt rms. That amp is 900 watt RMS at 2 ohms. If you only have 1 woofer, you can't possibly wire it wrong being all the subs I've seen in the results were 4 ohm. If you are using just one though, you should get a larger speaker, both 2 ohms and 1000 watt rms to prevent distortion. I'm afraid I can't answer your post without further information on the sub you are using.
