use the supplied jumper leads if its a dual 4 wire red to red and black to black and wire one set of red and black to amp ...if its dual two...use one jumper and go from red one side to lack other side and use remaining red and black to go to amp

Thanks CRX, so i have dual 2 ohms so this is the right way to do it ?

use imgur.com to upload pictures and just copy the bb code. Your pics arent working.

First one is 4 ohms, 2nd one is also 4 ohms. No difference. You wont get 2 ohms with a single D2 sub. You only have the option of series/parallel = 4 ohms final Or parallel = 1 ohm final.

thanks for the reply, but i thought the new alpine type r's where dVC 2 0hms . So there is no way to run it at 2 ohms ?

That sub pictured is definitely 2 Ohm DVC. Like Jeffdachef said, you can only wire it to 4 ohms or 1 ohm. If you added a second identical sub with the same coil configuration you could then wire the pair to 1 ohm.

What amp do you have?

ok thanks for the help guys, i get it now, im running an alpine mrp-m1000, I wanted to wire it at 2 ohms but i guess i can only do 4 ohms

Its a dual 2 sub ...so just run two sets of speaker wires from amp to the sub and hook up red and black to each side...if its a stereo amp it will see 2 ohms ..no need to use jumpers

Unfortunately that's your only option right now. It'll still get 600W+ RMS, which should definitely get it moving.

Wire it like you have it in that second picture, in series, with the one jumper.

I just saw this...yes 4 ohm will be your only option with that sub and amp combo....

Got it . I know its a know question but, in order to run a subwoofer at 2 ohms does it have to be dvc 4 ohms? And does Alpine make a sub that's 2 ohm compatible?

To get to 2 ohms with a single sub it either has to be a DVC (dual voice coil) 2 ohm (allowing 8 ohms or 2 ohms) sub, a SVC 2 ohm sub (pretty straightforward, one voicecoil, just straight up wire the positive and negative), or a DVC 1 ohm sub (allowing 2 ohms or .5 ohm, an impedence that many amps won't handle).

Alpine makes subs with the first two options. I know with the Type R series they make a D4 model: Alpine

If you get a second 2ohm sub then you can wire the two to 2 ohm final load or .5
