Not sure what you mean by AB but being that this is a monoblock or 1 channel amplifier you can only hook it up 1 way. Verify the polarity from your speaker box. + to + and - to -. As far as your impedance is concerned this amp is stable to 1.5 ohms but for this case we will assume you have two 4 ohm subwoofers. When you parallel these together you will have a total effective load of 2 ohms on the amplifier. This is a stable operating impedance for the amp.

Other impedance options are:

two 8 ohm speakers = 4 ohm load

three 8 ohm speakers = 2.66 ohms

If you have dual voice coil subwoofers then parallel the coils on each sub + to + and - to -. Depending on the impedance of each sub you may then have to wire the individual subwoofers in series. Here is an example.

2 dual voice coils with 4 ohm taps

Each subwoofer with the coils in parallel would be a 2 ohm load if you were to then parallel the two subwoofers together you would have 1 ohm total load on your amp. This is BAD for your amp. Your option is to run the subwoofers in series.

To run the speakers in series is simple. The + from one speaker and the - from the other will be connected to the amp. The other + and - from the speakers will be connected together.

Here is a wiring diagram from kicker.

First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short.

If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec.

Please let me know if you have questions, and thanks for using Fixya.

+ on amp output to + on speaker #1 to + on speaker #2. - on amp output to - on speaker #1 to - on speaker #2. This is a parallel circuit....4 ohms in parallel with 4 ohms = 2 ohms. IF it were wired in series....would represent 8 ohm load.

rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck

Hello storres18,

If you have the Kicker model number 06CVX122, with dual 2ohm voice coils, they can be connected to a mono amp at 2ohms. First jumper the voice coils in series, the dotted positive (+) to the undotted negative (-) (or vice versa). Each sub is now 4ohms. Then wire both of the remaining positives and negatives together on the amp terminals (in parallel). The amp sees a 2ohm load. Here's the diagram:

If you have the Kicker model number 06CVX124 with dual 4ohm voice coils, they cannot be wired to present a 2ohm load. They can only be wired as a 1ohm load (too low for the amp) or as a 4ohm load (at reduced power). Here is the diagram of the 4ohm wiring:

Hope this helps.

Hello magoocsl,

Yes, with the use of 2 high-pass and 1 low-pass crossovers, that Kicker amp will operate in what they call stereo and mono simultaneously (SAMS). You'd run 4 of the 6X9's in mono. Wire them in series-parallel with a low-pass crossover on the positive leg to the amp. The amp would see a 4ω load. The other two 6X9's would be wired as stereo, one to each channel with a high-pass crossover. Again, the amp sees a 4ω load.

Here's a link to the appropriate wiring diagram. The diagram is on page 5. Just substitute your 4 6X9's wired in series-parallel where they show the "mono" speaker.

connect each dual in series then parallel each sub

Sep 08, 2008 | Boss IQ 3KD.1 Car Audio Amplifier

You can connect them in a series/parallel configuration. Put two of them in series and then connect the last one in parallel across the two in series. This would give you an impeadance of around 2.7 ohms. Only do this if your amp is stable at 3 ohms or less. I am not familiar with the specs of your amp. If your amp is only 4 ohm stable you can not do this.

This would also give you half the power on the two subs in series as the power for the one that is parallel. The two in series would be sharing the total output signal, where-as the one in parallel would get the entire output signal from the amp.

if you were to connect a fourth sub woofer in this configuration it could give you a 4 ohm load, by adding the fourth sub in series with the single sub that is in parallel. or in other words, yu have two sets of 2 sub woofers each in series. That gives you two 8 ohm loads (two 4 ohm subs in series is 8 ohms). Then you take the two sets of subs and parallel them (two 8 ohm loads in parallel equals 4 ohms).

If i had a picture to show you it would make sense, two subs in series that are in parallel with two subs in series.

It sounds like you may have the load impedance too low.
How many voice coils per woofer?
How many ohms is each coil?
If you have DVC woofers, are the coils for each woofer wired in series or parallel?
Are the speakers wired in series or parallel.
Let me know if you need me to clarify anything.
