I'm a newbie to car audio so somebody school me on what im missing
Going to power a 12 inch single sub from 2 channels (bridged) off a JBL PX300.4 (300W into 4 ohms bridged)

Question: Should I worry about the 2 voice coils with my config or should I look for a single voice coil sub?

The other 2 channels are going to my front speakers. (Probably Focal PolyGlass or PolyKevlar 6.5")

Rear Speakers are Infinity Kappa Coax powered by my Alpine CDA-9833 HU.

I like clarity and SQ but I also want my lower frequencies to bump. I am also looking for a long lasting sub as I don't want to replace it anytime soon.

Here are the choices im looking at right now....feel free to add something! Budget US160

1. Alpine Type R SWR-1241D $106
2. Image Dynamics IDQ12 D4 V.2 $159.95 (Recommend by rcurley55)
3. JL Audio 12w3v2 $160
4. Infinity Kappa Perfect 12.1 $143

Thanks so much!

Edit: I listen to a lot of Hip Hop Maybe a sub that can play lower frequencies accurately is what I am looking for
