Ok. Here's the plan.

Building a new woofer box. Holding two 12's.

Specs:

Subwoofers:
Power Acoustik FUBR-12
700 watts RMS
Dual 2 ohm voice coil
1800 watts max

2-Channel Amp:
Power Acoustik LT1920/2
Bridged RMS Power @ 4 Ohms: 880W x 1
1920 Max Watts

Now, on to the question. How the heck am I supposed to wire these? I use to have the positive and negative going to one terminal on the woofer itself. However, aren't I supposed to incorporate the dual voice coils and use both + , - terminals?

I went onto Rockford Fosgate and found a Woofer Wiring Wizard...

and came up with these results:

2_2ohmDVC_2ohm.gif


OR

2_4ohmDVC_4ohm.gif


Is that correct? I'm a little weary about wiring + and - together. Then again, I don't have any knowledge in this field.

Help? :D

after you wire it up hit it with an ohm meter and make sure you're pulling 2 ohms resistance. your speakers say dual 2 ohm so hook em up like this

just make sure your amp can handle a 2 ohm load or you'll burn it up pretty quick. it should say what load it can handle somewhere near where you hook up the speakers, or on a sticker on th eunderside next to the model/serial number

dont forget to use screws for your box. :) so it wont split apart again
 
i just read your post again...

Subwoofers:
Power Acoustik FUBR-12
700 watts RMS
Dual 2 ohm voice coil
1800 watts max

2-Channel Amp:
Power Acoustik LT1920/2
Bridged RMS Power @ 4 Ohms: 880W x 1
1920 Max Watts

that amp is only 4 ohms, its not meant to handle those subs in dual 2 ohm the way that wiring diagram is set up.

setting them up like this:

should get you a 4 ohm load i believe.

someone please correct me if im wrong.
