Product details
Half-kilowatt mono punch
Five hundred watts RMS at 2 ohms drives many single or dual-coil subs. At 4 ohms the amp still makes 300 W RMS for simpler wiring. Mount the chassis to solid metal with the supplied hardware and keep cooling fins in free air. Size power and ground cable for the fuse rating, and set input sensitivity with a multimeter or oscilloscope after the speakers are connected.
Bass EQ beyond a fixed boost
Level, width, and frequency controls (30–100 Hz) plus 0–180° phase let you shape the cabin boom without a separate processor. Mount the chassis to solid metal with the supplied hardware and keep cooling fins in free air. Size power and ground cable for the fuse rating, and set input sensitivity with a multimeter or oscilloscope after the speakers are connected.
Remote included
Wired bass remote and cable ship in the carton so level stays reachable from the front seat. Mount the chassis to solid metal with the supplied hardware and keep cooling fins in free air. Size power and ground cable for the fuse rating, and set input sensitivity with a multimeter or oscilloscope after the speakers are connected.
