Answer 1

Go with the one linked below which is the same as yours from Rockford Fosgate.

I have never trusted crutchfield.

Answer 2

Parallel will up the resistance to 2 ohms, however if you are wiring to a stereo amp and will be bridging the 2 channels seeing 2 ohms a side will see 4 ohms at the bridge. Meening you will either need a 1 ohm sub or a dvc 2 ohm sub

Answer 3

Use wiring option #1 in the Rockford diagram, or wiring option #2 on the Crutchfield site.

Note that the top Crutchfield diagram is for a dual 2-ohm voice coil sub, and they're showing a wiring method for a total 4-ohm load. You want just the opposite.

Answer 4

To wire a 4 ohm DVC Sub to get 2 ohms you will need to connect the terminals in parallel. So what you do is connect the two (-) terminals on the sub together. Then connect the (+) terminals together. Then connect your amps (-) to either one of the (-) terminals on your sub. Then connect your amps (+) to either one of the (+) terminals on the sub and you should be good to go!

EDIT: I personally would use a good thick wire to hook everything together, say nothing smaller then 12 gauge.

Answer 5

They are all the same diagram (parallel vs. series wiring). The first web page (Crutchfield) has many more diagrams so I would just follow those (and ignore the second if that confuses you)

Answer 6

Parallel and use 10 AWG
