Although the 500/5 contains five channels, it functions more like a three channel amp. The five channels are divided into front channels (2), rear channels (2), and a subwoofer channel. In addition, each channel grouping sports its own unique power rating, frequency response, and even its own damping factor. For instance, the 500/5’s most powerful channel, the subwoofer channel, offers 250w of power at 5Hz-300Hz frequency and >500 @ 4 ohm. The Audio 500/5 also features a vertical, cast aluminum RealSink for improved heat dissipation, flexible preamp outputs, and differential-balanced inputs. Priced at $849.99, the JL Audio 500/5 is an expensive, but highly powerful solution for consumers seeking a multifunctional, multi-channel amplifier that packs a powerful punch.
