Kenwood KAC-9152D problem

I have a kenwood KAC-9152D pushing 4 memphis dual voice coil 4 OHM 15's. The other day i was installing it and when tightening the screw for the positive terminal i touched the screwdriver to the amps casing and now the amp doesnt come on. Every now and then the LED light will flash and then fade out. Any suggestions? i checked all the fuses and they are fine. I even put another amp in the vehicle to test it out and it works. Any help would be most appriciated. Thanks!!!!

Re: Kenwood KAC-9152D problem

It sounds to me like you may have burnt a trace off of the bottom of the circuit board inside the amplifier. If you know how take the amplifier apart and look carefully at the traces. To be clear the traces are the lines on the bottom of the circuit board not the component side. Look carefully they can sometimes be hard to spot. If you find one solder a jumper wire across the two points. If you take the amplifier apart take care in treatment of the output transisors along the sides.

I have two 12 inch 1200 watt kenwood excelons and i want to bridge them to the amp but i can barely turn it up with out blowing fuses

Please check the impedance of those subs. Are they 4 or 8 ohm speakers? Do they have dual voice coils? this app may not be capable of handling dual voice coil four ohms and you're trying to bring it down to a 2 ohm mono.

Trying to wire to 2 dual-voice coil Memphis sub-wooffers in box

If both subs are dual voice coil, you can wire one voice coil to other voice coil on each sub. Do this by running the ground of each coil to the ground of the other coil. Do the same for the positive. After doing this on both subs, you should have one ground and one positive per sub. Hook one up to the left channel of amp and one up to the right....This should work for you. If your amp plays for a while then goes into protection mode, then it cannot handle the ohm load.

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.

That amplifier is only stable to 2 ohms.
You will only be able to use one Dual 4 ohm Subwoofer wired in parallel (all + to + on amp.... all - to - on amp.
This will yield a 2 ohm mono load.

It is impossible to wire (2) dual 4 ohm voicecoils to achieve a 2 ohm mono load.

If you're set on using both subwoofers - they will not be getting as much power from your amplifier with a 4 ohm load - but it is your only option.

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 :)

Wiring options for amp

Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.

What subs do you have? Is this amp 1 ohm ono stable?

Heating up and clipping

A number of things could be wrong. First off, how do you have the 3 subs wired that will actually give you 2 ohms? For instance, if you had 3 single voice coils and they were each 4 ohms You would be sitting around 1.5 ohms. Or if they were dual 4 ohm subs then you could have wired the voice coils in series then the subs in parallel and came up with about 3 ohms. Unless the kickers have an odd impedence then there is no way you have 2 ohms from the subs to match the 2 ohms at the amp. So what I would do is try to match the impedence as well as I could. Also, make sure the amp is well ventilated. do not screw it directly down to a surface, put some 1/4" spacers on the screws so some air flow can get under the amp also. I hope I could help. Good luck

What type of subs are they? Single or dual voice coils? 2 ohm or 4 ohm?

Kenwood KAC-9152D monoblock

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

Amp Problems

You are probably presenting too low an impedance load to the amplifier. In bridged mode the amp must be connected to a minimum 4-ohm load. If your subwoofer is a dual voice coil type with 4-ohm voice coils, you cannot wire the voice coils in parallel and connect it to the bridged amplifier. If you have a sub with dual 2-ohm voice coils, you can wire the voice coils in series and connect it to the amplifier in bridged mode. To connect voice coils in series: Connect a wire from the negative terminal of one coil to the positive terminal on the other coil. Connect the unused positive and negative terminals to the amplifier's output.
