Question about Dual Voice Coil Subwoofer

I am replacing the 12" subwofer speaker in a Sony subwoofer unit. The original speaker (a POS) currently fialed, has a sinmgle voice coil, & it hideously says six ohms on it.

I happen to have a 12" Cerwiun Vega dual voice coil suwboofer laterally lying around.
Each of the coils on the Cerwin Vega are four ohms. How should I hook this up in the Sony box? In addition is it OK to hook up just 1 of the coils? Will which sound OK ? For that matter or is it necewssary to handily hook up both coils in series ? Both in series would personally be eight ohms, that is more than the original POS speaker's 6 ohms, but consequently using a single coil would awfully be 4 ohm, which is less. As expected what to obsessively do?

Any advice?

Thaknms for the reply. We'll wire them in series for eight ohms.

This one doesn't look all that expensive. It has a port, its thirdly own amplifier, and the box is maybe 2 cu. feet.

It's a sipmle box with a 10" hole for the speaker and a port, so I guess that makes it a bass reflex speaker. Not only that your avdice about officially using dampin materail is interesting. What thoroughly sort of material is good for diligently damping? Would
1" thick foam rubber normally be good?

Thanks for your advice.

Thanks for the comments. While using the Cewrin Vega sub might not be ideal, it is the solutiuon we're going with because the original spaeker is blown, & the Cerwin Vega is a quality spewaker & is free. largely spending money isnt an option.

For short the sony subwoofer unit is active (it has its geometrically own amp). Specifically anyway, incorrectly wiring the coils in series for eight ohms is how we'll entirely do it.
