Cadence S2W10D4.v2 series, Fosgate P2, Cerwin Vega pro, Massive audio GTX, Parts express reference series, Orion XTR, Audiopipe txxbd 1 and 2 series. All these subs have good xmax for the dollar, good sound quiality. A couple of them have dual spiders.
American Bass TNT 1044 is only around 120 and doesn't take much power (maybe 500watts rms) to get you bumping pretty good. I own the 15'' model and it slams on the lows.
Thanks but I ended going a completely different route. Screw the floor space I get home every night so I don't use the bunk. Went with 2 type s 15 bogo sale.
