Our take on the Power Acoustik OD41800 1800 Watt 4 Channel

The Power Acoustik OD41800 is a Class A/B four-channel car amplifier from the Overdrive series. It is rated at 140 watts RMS per channel at 4 ohms, 225 watts RMS per channel at 2 ohms, and 450 watts RMS bridged into two channels at 4 ohms, with a 1,800-watt peak rating. It is 2-ohm stable, bridgeable, and has variable crossovers, RCA outputs and a three-step bass boost. It suits budget-minded builds that need one amp to drive front speakers and a sub. Against Class D rivals it runs hotter and draws more current, but Class A/B designs are simpler and cheaper to build.

Pros
  • Four channels cover front speakers plus a bridged sub
  • 2-ohm stable on all channels
  • Bridged output of 450 watts RMS per pair
  • Variable low-pass and high-pass crossovers
  • Bass boost selectable at 0, +6 or +12 dB
  • RCA outputs for daisy-chaining a second amp
Cons
  • Class A/B runs hotter and less efficient than Class D
  • Peak 1,800-watt rating overstates real output
  • Only two 25-amp fuses, so it needs a solid power feed
  • No subsonic filter or DSP
  • Bass boost is a fixed three-step switch, not fully variable

Questions and answers

Is 1,800 watts the real power output?
No. That is the peak rating. The continuous RMS ratings are 140 watts per channel at 4 ohms, 225 watts per channel at 2 ohms, and 450 watts per bridged pair at 4 ohms.
Can it run two speakers and a subwoofer?
Yes. Use two channels for the front speakers and bridge the other two into one subwoofer channel. Bridged output is 450 watts RMS at 4 ohms.
Does it need a separate power wire and fuse?
Yes. It has two 25-amp fuses on board, but you still need a fused power cable run from the battery sized for the amp's current draw.
What crossovers does it have?
Each channel pair has a variable 12 dB crossover. The low-pass adjusts from 50 to 250 Hz and the high-pass from 120 Hz to 3 kHz.
Can I add a second amplifier later?
Yes. The RCA outputs pass the signal to another amp, so you can add a dedicated sub amp without running new cables from the head unit.
How big is it and where can it mount?
It measures about 7.25 inches wide, 2.5 inches tall and 14 inches long, so it fits under a seat or on a trunk panel in most cars.
Where is the Power Acoustik OD41800 1800 Watt 4 Channel cheapest?
At Horizon Gear Co., for $136.99, as of our latest check.
