How do i wire 2 12inch dual voice coil 4ohm to 1ohm to mtx ta81001 amp?

The wiring of the amp is not what makes it 2ohm or 4ohm, it is the resistive load of the sub, The issue is that your sub, assuming it is the L5 Kicker mentioned above has dual 2ohm voice coils, This means that if run in series will provide a load of 4ohms which will work fine but not make the most of the amp which would only be supplying 425w of it's potential 700w.

if you wire the voice coils in parallel you will end up with a load of 1ohm which will cook the amp.

here is a link to a page that explains how it all works.

Hello montyski20,

The amp outputs 500 watts RMS into 4ohms, 750 watts RMS into 2ohms and 1000 RMS into 1ohm.

The L7 can handle 750 watts RMS (375 watts per each coil). If your L7 is the 2ohm version, you should wire the voice coils in series, the positive marked coil to the negative unmarked coil. Then connect the remaining positive and negative to the amp terminals. This gives you a 4ohm load (500 watts). If your L7 is the 4ohm version, wire the voice coils in parallel, both marked and unmarked positives together, likewise both negatives and then to the amp terminals. This gives a 2ohm load (750 watts).

Paralleling the 2ohm sub will result in a 1ohm load (1000 watts) and that is too much for the L7.

Hope this helps.

Hello rigo11785,

The MTX Thunder 1501D is stable at 1ohm and outputs 1,500 watts RMS into that impedance. An L7 with 2ohm DVC's would present a 1ohm load if wired in parallel and would allow the amp to produce more power than into the 4ohm series load. The problem is that the L7's maximum power handling rating is only 1,000 watts RMS, so if you wire the coils in parallel, you'll very likely overdrive the sub and perhaps damage it. Now, if you bought another L7 and ran the voice coils in series and the subs in parallel, that would be a 2ohm load and well within their power handling capability.

With that amp and sub, I'd recommend leaving the voice coils in series.

Hope this helps.

Hello ereza25,

The best way depends on what amp you are using to power the sub. With dual 2ohm voice coils, you can wire to either a 1ohm or a 4ohm final load. If you are sure that your amp is stable down to 1ohm, that wiring will provide the best power to the sub. But if the amp is not rated at 1ohm (many aren't), then the 1ohm wiring will result in overheating and possible damage to your amp.

The wiring diagrams are here. Hope this helps.

Hello jose08042008,

Your sub has dual 2ohm voice coils and can be wired to present a final load to the amplifier of either 1ohm or 4ohms. Unless you have an amp that is stable at 1ohm (not many are), then you will want to use the 4ohm wiring. To wire for 4ohms, jumper the positive terminal of one voice coil to the negative of the other terminal, and connect the remaining positive and negative terminals to your amp. If you know for SURE that your amp is stable at 1ohm, you can connect both positives and both negatives together on the sub and then to the amp. But if the amp 1ohm stable, this will result in overheating, and/or going into "protection" mode, and/or damage to the amp.

Hope this helps.

Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

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 i_starling,

The Kicker L7's come in either 2ohm or 4ohm dual voice coil (DVC) versions.

Whatever amp they are connected to, you need to know both the impedance of your L7's and the impedance of your amp. The L7's dual voice coils can be wired to provide a total of four different loads:

2ohm coils in parallel = 1ohm load
2ohm coils in series = 4ohm load
4ohm coils in parallel = 2ohm load
4ohm coils in series = 8ohm load

Your best connection would be the one that results in a final impedance load that is supported by the amp.

Hope this helps.

Well first of all all solobarics are dual voice coil so you have 2 2ohm voice coils so if you wire them in parallel the sub will be pulling a 1ohm load wich would in time blow out your amp. So you want to wire both voice coils in series to produce a 4ohm load.

parallel wiring. hook all 4 positives together and run to the positive output from the amp, hook all 4 negatives together and run to the negative output from the amp.

hope this helps,
