Our take on the Monoblock 1200W RMS 1-Channel Class D Car Amplifier

A single-channel Class D car amplifier rated at 1,200 watts RMS, built to drive one subwoofer. Class D runs cooler and draws less current than Class AB at this power level, and the onboard bass control lets you tune the sub without a separate processor. It is a bare amplifier: no wiring kit, no subwoofer and no enclosure are included.

Pros
  • 1,200W RMS is real subwoofer power, not a peak rating
  • Class D efficiency means less heat and lower current draw
  • Bass control lets you shape output at the amp
  • One channel keeps the install simple: power, ground, remote, sub
  • Monoblock design is stable into low subwoofer impedances
Cons
  • No wiring kit, fuse or subwoofer in the box
  • 1,200W RMS needs a stout alternator and a fused 0- or 4-gauge run
  • No built-in DSP or crossover beyond the bass control
  • Cheap Class D amps often fall short of their rated RMS

Questions and answers

Is 1,200W RMS enough for one subwoofer?
Yes for most single subs. A 1,200W RMS amp comfortably drives a 500-1,000W sub with headroom, which keeps distortion low. Match it to the sub's RMS rating, not its peak.
What else do I need to install it?
An amp wiring kit rated for the current (fused 0- or 4-gauge power wire), a remote turn-on lead, RCA cables and speaker wire to the sub. None of these come with the amp.
Will it work with my factory head unit?
Only if the head unit has preamp outputs, or you add a line-output converter. The amp takes RCA input and needs a remote turn-on signal.
Does it fit a 2-ohm or 1-ohm sub?
Monoblock Class D amps are typically stable down to 1 or 2 ohms, but check this model's rated impedance before wiring. Running below the rated load can trigger protection or damage the amp.
How much power does it draw from the electrical system?
At full 1,200W output it can pull well over 100 amps, so plan on an upgraded alternator or a second battery for sustained full-power play. Normal listening draws far less.
When is it cheapest?
Car audio amps tend to drop during holiday sales and end-of-season clearances. Watch the price history and buy when it sits near its recent low.
