The JBL BassPro 12 is a 12-inch subwoofer already mounted in a ported MDF enclosure with a built-in amplifier, so it drops into a trunk or hatch with power, ground and signal wiring only. JBL rates it from 30 Hz to 200 Hz with an adjustable low-pass crossover and a 25A fuse. It suits drivers who want real low-end without building a box or matching a separate amp. Against component subs it gives up tuning flexibility and some output per dollar, but it is simpler to install and harder to get wrong. Owners rate it highly for the bass it adds for the effort involved.
