The Hifonics BG-1300.1D is a Class D monoblock subwoofer amplifier rated at 325W RMS into 4 ohms, 650W into 2 ohms and 1,300W into 1 ohm. It pairs a variable 30–250 Hz low-pass filter and variable bass boost with a bass remote knob, so you can tune and adjust the sub from the driver's seat. Nickel-plated, angled terminals and Hifonics' aluminum chassis make wiring and cooling straightforward. It suits budget-minded bass builds that need a lot of power at low impedance; rivals in its class often add speaker-level inputs or preamp outputs, which this amp lacks.
