American Bass USA XFL 1244 vs Rockville W15K6D4 V2 15" 4000w Car Audio Subwoofer Dual 4-Ohm Sub CEA Compliant

The American Bass USA XFL 1244 is a relatively good Car Subwoofer for people that are willing to spend around $260. The Rockville W15K6D4 V2 15" 4000w Car Audio Subwoofer Dual 4-Ohm Sub CEA Compliant, by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.

In both cases, however, we recommend that you take look at some other options at the $260 and $170 budget ranges; in all likelihood you'll find some better alternatives.
