Amplifier wont move subs

There are a couple different ways you can wire up this speaker as it is a DVC speaker. Duel Voice coil, it has two + post and two - post. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance.
You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier - one voice coil per channel
Depending on what you are hooking it up to i.e. a mono amp or a bridged four channel amp. I can tell you post to wire exactly if I know how you want to hook it up and what ur hooking it up to.

Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

hook the positive to positive and negative to negative on both subs then run wire to the amp the amp will see a 2ohm load

well u run a power wire atleast 4 guage from the positive terminal on the battery, then 4 guage to a chasis ground source, then a remote wire to the rear of your cd player that will kick the amp on when the cd player turns on... then for subwoofer wiring go to www.the12volt.com for sub wiring options... you need either single voice coil 4 ohm subs or 2 ohm dual voice coil subs to get the 2 ohm load to the amp so u can get the rated power out of it...

Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

Hi!

Having to much power for a subwoofer is a veeeery good thing, it will provide a lot of control and quality sound to your sub.

But this sub is a dual voice coil at 2 x 4ohm so if you want to hook it up at 4 ohm u need a 2 channel amplifier running mono mode.

i dont recomend that you hook up in 4 ohm, its better to take some time adjusting the levels on the amp and the headunit.

This system has the potential to create a realy good bass sound if u tune it the right way.

Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

Hi Gott Mudd,

 

I can relate to feeling it in the bones. You got the stuff to do it.  You should try the Alpine MP3 head units with bass boost, those are bad to the bone.

 

Wiring: 

 

Amp to Speaker I like to use the code VC for Voice coil, and AO for Amplifier output.  Also + for positive.  If I say VC1-, I am referring to the first connector starting left to right on the Alpine Sub. Now I have not seen a Kicker KX1200.1 amplifier.  All I see are MRA, MRP, or PDX prefix on the part numbers. So take what I am saying as a guess. You may want to revisit looking at the model of the amp to be sure your giving the right information.

 

We are going for  2 Ohms. Paralleling the two subs, not the voice coils. The voice coils will be series.  Bridge the amp if necessary to get mono channel. only using AO+ and AO- for output.

 

AO+ to Sub1VC1+

AO+ to Sub2VC1+

Sub1VC1- to Sub1VC2+

Sub2VC1- to Sub2VC2+

AO- to Sub1VC2-

AO- to Sub2VC2- 

 

Set your Crossover to LPF

Adjust the bass gain down to lowest until you test.

Set the Frequencies to midrange between 40 and 100hz  

 

Your box can be ported or not. It depends on the space your have.  If you do not have much room, go Enclosed and build a box that the inside space is less than 1 cubic foot.  Make sure you give barely  enough clearance for the speaker to fit.  If you have room, Go with a box and vent it with a 3 inch Vent tube 10 inches long.
