This speaker wire is good, there are two separate wires, they are just twisted together for some reason, this is better then the universal hard plastic 12 gauge wire
This Kicker CompR 40CWR122 subwoofer features a 12" injection-molded polypropylene woofer cone and a large-diameter, progressive-roll spider with Spiralead tinsel leads to enhance your vehicle's music, so you can enjoy rich, crisp audio on the go.
I like it a lot, pumps bass, makes system enhanced not reallly making it crazy good. I run a 2400 hifonics on these and I haven't really been able to pump them too hard bc my lights dim, definitely a lot of watts but overall good speaker, whatever they say about a closed enclosure is not true, the ported sounds much better for that hard hitting bass with these subs, make sure the box is divided in the center almost like there are two differnt boxes
