How to wire a 4ohm dvc and 2 ohm dvc?

I currently run an Alpine MRV 1507  with an Alpine SWR 1522D.  How can I wire another sub, but this one is a SWR 1542D? What would your ideal wiring set up if you had my components?

Thanks

Alpine SWR 1522D I would use the ONE. yes 1 sub, dual 2ohm coils and wire it like this. At 4ohm mono that alpine should yeild 6 to 800 watts. Just make sure you have the reserve in your battery, and a decent alternator. Just My opinion.

Recommended Amplifier: Stable at 4, 2, or 1 ohm mono
