wiring an alpine swr 1221d sub

how to connect this thing to a mono or 2 channel amplifier?

This sub (yes only 1) has dual voice coil which is 2 ohm each coil. 150 rms each coil.

What connection to make it 4 ohm? And whats the effect on its rms on this set-up?

Or when i leave it 2 ohm each voice coil running to each channel of a 2 channel amplifier? Is this safe for the sub/amp?

Last one, how can you make it to 2 ohm single wired sub to run into a mono 2 ohm stable amplifier?

I hope i dont confuse you guys and gals. :pat:

Nothing wrong with having only 1 subwoofer.

Depends on the amplifier. To make your situation easiest, just wire it up in a mono configuration. See the above picture.

You don't. That would only work if you had a Dual 1-ohm OR dual 4-ohm. Your subwoofer will only allow a single 4ohm or single 1ohm load.
