Need help installing 1 DVC and 2ch amp

[RobinD90]

Hey guys, I hate to ask a serious noob question, but I'm working on limited time here and need some help.

I have a Rockford Fosgate R250D-1D Amp and an Inifiny 1262w sub. Now, when I bought these it was black friday, the deals were great and, in short, I didnt do ALL of my research. I did NOT know at the time that amps could be non-bridgeable, so I bought it thinking I'd be good to go...well now that I've got everything but the sub and amp wired up I decided to double check everything and came upon this little fact. So now I need a solution. Anyone willing to help me out? If it helps I can post my HU and other speakers, but I only plan on using the amp to drive the sub.

Its a mono/bass amp only,and is non bridgable..Its ready to hook except any subwoofer with a final load of 2ohms stable..You have 2 +, and 2-,they are on the same pole internal, so chose one +, and one - for your DVC4ohm sub, and make sure its wired as this diagram for the 2ohm load for the amp

Awesome, I'll give it a shot! Thanks. So just to be clear, I'll be running from the + of one channel on the amp, to the sub+, then from the sub- on the other coil to the amp- on....which channel of the amp?

It will be fine of either, as they are on one pole ea inside the amp..This dual connection was made to help make it easier for the wiring to be placed on the connection of the amp rather than having 2 wires poss tied together ,and 2 negative wires in a big clump to try and wedge in one location of the bridged connection for a pair of subs..Now with these double connections , you can add ea sub to ea post without it being all clumped up,bridges internally on the same post

So on the amp, I'll be hooking up one positive, and one negative on the same channel. I.e [+-XX] OR will it be [+XX-]? If that makes sense.

Sorry this is my first time hooking up an amp and sub :/

If you run the one positive from the amp to the positive on voice coil #1 and the other positive to the positive on voice coil #2 , then run one negative from the amp to the neg. on coil #1 the other to neg. on #2 , it will be the same as wiring them like the parallel diagram. Either way will work.
