The first thing you must do is to confirm that you have voltage at the amp. Just because the fuses look good, that doesn't mean you're getting power to the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

SOURCE: 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.

SOURCE: want to bridge my subs I have a kenwood kac-719

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

I have 2 mtx 12"woofers (8ohms each wired parallel to get to 4ohms) which Kenwood amp would be best to use: kac-7252 or kac-9104d?

The Kenwood KAC-7252 and KAC-9104D are both great amps, but they have different strengths and weaknesses. The KAC-7252 is a 5-channel amp that can output 75 watts per channel at 4 ohms. It also has a built-in crossover and time alignment, which can be helpful for getting the most out of your woofers. The KAC-9104D is a 4-channel amp that can output 100 watts per channel at 4 ohms. It also has a built-in subwoofer output, which can be used to power a separate subwoofer.
If you are looking for an amp that can power all of your speakers, the KAC-7252 is a great option. It is also a good choice if you want an amp with built-in crossover and time alignment. However, if you are looking for an amp that can power a subwoofer, the KAC-9104D is a better choice. It is also a good choice if you want an amp with more power output.
Ultimately, the best amp for you will depend on your specific needs and budget. If you are not sure which amp is right for you, it is always a good idea to consult with a professional car audio installer.
Here is a more detailed comparison of the two amps:
Kenwood KAC-7252
  • 5-channel amp
  • 75 watts per channel at 4 ohms
  • Built-in crossover and time alignment
  • MSRP: $399
Kenwood KAC-9104D
  • 4-channel amp
  • 100 watts per channel at 4 ohms
  • Built-in subwoofer output
  • MSRP: $499
I hope this helps!

Kenwood kac-9104d stopped working was in car music loud amp stoped worked I stop to change fuse it wasn't blown popped hood that amp was blown don't know what's wrong with it

Turn your gain below half. Make sure you have a solid ground, not a seat belt bolt. The fuse blew to protect the vehicle because there was too much power being pulled by the amp, possibly from overheating.

How should i have my 4ohm single voice coil JL audio 12in subs connected to my kenwood kac-9104d 1800 watt max power (500x1 @4) amplifier?

On the outputs of the amp there is:

+ + - -
1 2 3 4

terminals. Internally in the amp the positives (1 and 2) are connected together and negatives (3 and 4) together. So there is no difference between hooking up in any of the configurations 13, 14, 23 or 2->4. If its a matter of style, probably use the 14 set, since they're furter apart and harder to short out that way, but electrically it doesn't matter.

I have a Kenwood KAC-9104D that will power on but not produce any sound??

Be sure the RCA cables are attached and in good condition.
Be sure the remote wire from the deck is hooked up and good.
Be sure the GAIN control is turned up.
Volume on head unit is up. Make sure BASS options are not turned off on deck.
Be sure wires are going the right way. + to + & - to -
Loose wires in the box. Make sure subs are hooked to the terminals inside box.
Check all fuses on amp to determine if 1 or more i blown.

I have power , but the amp wont turn on

Where is your ground located?
It never hurts to put a beefy ground on an amp. If you do have it grounded take the bolt out use a wire brush on the bolt and on the surface you are grounding to. Also check our remote wire(blue). The purpose of this wire it shuts your amp down and turns it on when you turn on the head unit.

I recently purchased a new Kenwood KAC-9104D 1800 amplifier. I hooked it up just as I had with a previous amplifier but it wont power the subwoofers. When one of the RCA cables is plugged in and the other...

You should check and verify first the output signal in the amplifiers by using a multimeter on the db range, this is to identify good output of the amp. After that check the polarities for correct wire orientations.You should connect the speakers one at a time to check.

KAC-9104D pops fuses at medium to high volume. worked fine in my car, and when i put it in my friends somehow it stopped working. coincidence or my fault idn but i need to figure out whats wrong. any help?...

make sure that the connected speakers have the correct impedance. should be 4 ohm typically. some amps support 2 and 1 ohm, too. wrong impedance could occur when you connect two speakers in a row for example. it's all about electric law.
