Cool bass
Pioneer's handsome GM-DX871 mono subwoofer amplifier can deliver up to 800 watts RMS to your subwoofer, for powerful bass that'll give every song a strong and heavy beat. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a small chassis that fits in a lot of out-of-the-way spaces. And this little workhorse can handle a 1-ohm load, so you won't have to worry too much about impedance matching when you add another sub to your system down the road.

Connections and tuning for all occasions
Speaker-level inputs allow you to install this amp in a factory system with no RCA connections — the amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. The amp's got a low-pass filter that lets you quickly sharpen and focus the bass to suit your vehicle's interior, and a wired remote boost that lets you control the amount of bass boost from the front seat. This limited-edition amp uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance.
