What is the model of subwoofer and what kind of amplifier are you using? Not very many amps can handle a 1 ohm load. Also, how many subs are you planning on using

I have a rockford fosgate 1001d and 2 audiopipe dvc 12s need 2 know how wire speakers

Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM SOLUTION 1 If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers. Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers. RECAP: all positives together on the positives and all the negatives together on the negatives. This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care. SOLUTION 2: Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1 Do the same for subwoofer 2 now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative. This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier. SOLUTION 3 If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution. Connect like solution 2. This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power. good luck and drop me a line if you still have doubts. dreamsystems

I have a ts-w307d4 pioneer sub woofer and its a 4 ohm sub that has 4 terminals on it 2 red and 2 black how do i wire this sub to my amp i have a sony 1200 watts stereo amp and my sub is a dual voice coil...

conect one of the positive terminal from the sub directli to one chanel of the amp, and do the same with the negative,and do the same with the others terminals from the sub conect to the other chanel

How do i wire a kicker cvr if it has two reds and blacks

the sub is a dual voice coil, and depending on how you wire them, gives you different bass response as it drops the ohms in your amp. it can be wired for 2 ohms one way 4 ohms another way or 1 ohm depending on what ohm the coils are. to learn more about this got to rockford, click support, then click woofer wiring wizard, this will answer all your questions about dvc subs.

if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

I cant sem to wire it to 4 ohms because the terminals are right next to each other and i have no clue which 1 is which voice coil?

test with a digital multimeter set to ohms. if you don't have one of those laying around grab a 9 volt battery and run wires from the 2 terminals on the battery to 2 of the terminals on the woofer. if the woofer pops out you are said to be "in phase" (even though it has more to do with polarity that phasing but regardless) which means the positive from the battery is on the positive of the woofer and the negative is to the negative. those 2 terminals on the woofer are a single coil and obviously the other 2 terminals are the 2nd coil. now depending on what impedance each coil is will determine how you have to wire it to be 4 ohms unless they are 4 ohm coils which means you just use one coil and it will be 4 ohms on that woofer.

Does two 1ohm woofer = 2 ohm

if you buy the 4 ohm subs you can drop each of them to 2 ohm and then down to 1 ohm between the two of them. going with the 2 ohm no matter how you wire them you will either get 2 ohms 4 ohms or 8 ohms. hope this helps by the way the 4 ohm solobaric and the 2 ohm are both the same price.

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS

Hi yeahonda,


Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.


AO+ to VC1+

VC1- to VC2+

VC2- to AO-


This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".


If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.
