Question about Kicker Solo-Baric L7 S15L72 Car Subwoofer

Dual 2 ohm sub can be wired to achieve a 1 or 4 ohm load.

Dual 4 ohm sub can be wired to achieve a 2 or 8 ohm load.

Usually no difference in Theile Small Parameters.... Only wiring configuration - to get the most power out of your amplifier.

Is the amp a single channel? If so, the only way to connect the subs (without overloading the 2 ohm stable amp) is to wire each sub's voice coils in parallel (2 ohm) and then connecting the subs in series (4 ohms). If the amp is two channel, the subs can have their voice coils connected in parallel (as before) and then each sub connected to its own channel.

- kkkjohnson - Please clarify your question. Do you mean they stopped working all together.

-First make sure the amp going to the subs is still working. -If not, stop and trouble shoot the amp (fuse, loose wires,etc) -If it is working, check the wires going from the amp to the subs -If the wires are connected, your next step should be to dismount the subs and hook them up to a digital multi-meter (DMM) To use a DDM to test the subs ohms do the following:

Figure out what the specs of you subs are...ie...what ohms and voice coils the are (dual 2 ohm, 4 ohm, etc. After that, place the black/negative wire/lead coming from the DMM tol the negative terminal of the sub. The place the red/positive wire/lead to the positive terminal of the sub. Then set the DMM to the ohm symbol. It should look like a horse shore symbol. Then allow 5 or 15 seconds for a accurate reading of what the ohms are. For instance a dual 2 ohm sub should read anywhere from 1.6 ohms to 2.4 ohms...each sub is difference. Check both sides/voice coils if it is dual voice coil subs. For instance if your sub is dual 2 ohm sub and you get a read that is higher than the numbers listed above (ex. 8 ohms, .05 ohms, etc); this would indicate that you have a blown sub.

Ok, your post has two different models listed. Let's start with something you need to know about your amplifier. Is it one ohm or two ohm stable. This will make a difference. Also, whether your subs are single voicecoil (HFI12s4) or dual voice coil (HDI12d4).

Let's start with the easy scenario. Let's say your amp is two ohm stable and you have two single voice coil subs. It's simple. You go from the positive of the amp to the positive of both subs and the negative of the amp to the negative of both subs. This will provide a 2 ohm load to the amplifier, thus pulling all the power out of it.

Unfortunatley, if you have two dual voice coil subs, you won't be as efficient. You will only have the options of a 4 ohm load or a 1 ohm load.

This is where having a one ohm stable amp would come in handy. If the amp is one ohm stable, hook the positive of the amp to all 4 of the positives on the subs, and hook the negative of the amp to all 4 negatives of the subs. This produces a 1 ohm load.

WARNING!! If you have a 2 ohm stable amp DO NOT use the last wiring scenario. It will fry your amp.

Now, the last is a little trickier. This is for two dual 4 ohm subs. Follow closely. Hook the positive of the amp to one of the positives of each sub. (do the next step to both subs) Go from the negative of the voice coil that you hooked positive from the amp is hooked to, and hook that to the positive of the unused voice coil. Then go from the negative of that voice coil and hook to the negative of the amp. Make sure this is done on both subs. This will give you a 4 ohm load.

Hope this helps

Is your sub single or dual voice coil. This will also make a difference in choosing amps. Pretty much any amp that will supply your required power will do. But, if you have a single voice coil sub, you will be wanting to look for RMS power at 4 ohms. If you have a dual 4 ohm voice coil sub, you can wire it to a 2 ohm load. Then you will need to search for amps that supply the RMS requirements of the sub at 2 ohms. The choices are almost endless. I am an RE Audio dealer, so I absolutely know that they will do you well. Hope this helps.

Unless you have a 2 channel amp, the best you can hope for is a 4 ohm load. If you hooked both subs up in parallel, you would get a 2 ohm load for each sub. You would then have to wire them in series to equal a 4 ohm load. Even if you wired each sub in series, or a 8 ohm load, then both subs in parallel, you get a 4 ohm load. The other outlandish option is to get 2 more dual 4 ohm subs. Then you can get to a 2 ohm load. Sorry, I'm sure that's not what you wanted to hear.

Depending on the PA FUBAR you have. The voice coil on those subs are DVC. Dual Voice Coil. You need to know a couple things. What kind of amp are you going to run on it. And what is the resistance (OHM) rating of each voice coil. MY two 12's are dual 4 ohm. Meaning that there are essentially 4 speakers to hook up. My amp currently is not 2 ohm stable in bridged. So what I did is run each speaker in parallel (red2red,black2black) then run to the box terminal. So now the dual 4 ohm voice coils are basically 2 ohm. I have 2 speakers. Now I hook the box up in series. To bring the now two 2 ohm speakers into one 4 ohm speaker. This is called series/parallel setup. My amp sees this box as 1 channel @ 4ohms. The downfall to this is the output of the amp is divided up into each speaker. So instead of sending all 1400 watts to one sub. I will send 700 to each sub. But here is a catch. even though each speaker is half the total wattage it will still be 3db louder. Meaning it will be as loud as 1 sub running 1400 watts. To conclude i need to know how many of those subs you are going to run on the amp.. And the model number of the amp so I can match up your wiring.

The amplifier is only stable to 2 ohms.

Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.

You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

If the subs are dual 2 ohm voice coils.....

- For a each sub, connect one of the "+" terminals on the sub to one of the "-" terminals. This makes each sub 4 ohms.
- Connect the unused "+" terminals of each sub together. Do the same with the unused "-" sub terminals. This makes the sub combination 2 ohms.
- Then connect the "+" and "-" sub terminals from the above step to the amp.

I would suggest you go with the 4ohm. It won't be a loud but it will be more stable. You will be less likely to blow up your amp with the 4ohm.

Both + on Both Subs to + Terminal on amplifier.

Both - on Both Subs to - Terminal on amplifier.

Both - on Both Subs to - Terminal on amplifier.
