I have a Kenwood kad-9104d mono amp hooked up to a MTX T9515-44 sub with each coil wired to the amp in its own terminal although this amp only has one channel (500w rms x1 @ 4ohm, 900w rms x1 @ 2ohm). This is the tricky part: two 4ohm voice coils wired to one channel will represent a 2ohm load and the sub is rated to withstand up to 1000w max power per coil @ 4ohms so my question is: What is the power rating for this sub @ 2ohms for each coil and also I must admit I had to do something right because I dont have any problems with my system, sub hits hard and amp dont get hot nor cut off and I never turn my system up with the engine off, only with the engine on to protect my charging system, p.s. those long bass notes will drain your battery.

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.

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.

either ur ohm load is way off ur pos n neg might be touchin or more than likely u blew u sub is it scratchy when u push in the middle of the cone ? does it push in at all?

You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.

If you can setup the Amp as a Mono Amp this will work for you very well unless the Amp needs a 12ω Load when setup for Mono Operations. You will want to hook the Two Subs in Series so that the Amp will see 1 8ω load. This means you will hook a wire to the Positive pole of one Sub and hook the Negative Pole to the Positive Pole of the Second Sub and hook the Negative Pole to the Amp's Negative pole. This will reduce the overall output but will end up having better reliability of the Sub since each sub will only see ½ the overall output of the Amp and you will still get the full output of the Amp.

This feature allows the amp to be paired to any stereo. The input may be in stereo but the amp then changes it back into mono using sound from both sides. Hope this answers your question.

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

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?

Hook the speakers in series to decrease your chances of blowing the amp and/or speakers themselves. And at high volumes make sure that the bass control is set for flat response.
