JL Audio 15W3V2 15″ 1000 Watts Subwoofer
JL Audio has been specializing in car audio products since 1975 (national distribution of JL’s subwoofers began in 1992), and it goes without saying that JL Audio has long been considered a major player in the subwoofer marathon that we have been witnessing for the past years. Known for their innovative engineering approach to speaker design, JL Audio has produced some very real improvements in subwoofer technology. They were among the earliest companies to use layered voice coil windings beyond four layers, and their patented vented reinforcement collar (VRC) that greatly strengthens the critical bond between the voice coil former, spider and cone was also a smart idea for its time.
The 500/1 is a single-channel, class D subwoofer amplifier with a power rating of 500 watts into any load between 1.5 ohms and 4 ohms. Features include the Regulated Intelligent Power Supply, which is responsible for the single power rating, differential inputs, buffered preamp outs, internal crossovers with variable cutoff frequencies and selectable slopes, a parametric bass boost circuit with wired remote, and a variable infrasonic filter.

The 250/1 is a dedicated subwoofer amp with serious power, design flexibility, and control. A built-in crossover determines which notes the subs handle, and variable bass boost lets you kick up the low (48 Hz) bass notes.
