Review: Running 4000watts max off these 2 mafkas, have them wired to 1.34 ohms, barely turned up a quarter on amp and they just slam, no problems yet, I’ll try keep an update on it as the months go on, you just gotta do your studying on your wiring job and what works best they maybe cheap but can compete with pro amps when set up properly
Review: Super

## Features

- POWER: 4000 Watts Max x 1 @1-Ohm, 2000 Watts Max x 1 @2-Ohms
- CLASS D: Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
- 1 OHM STABLE: Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
- STRAPPING CAPABLE: You are able to strap TWO AR4000D amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power
- VARIABLE SUBSONIC FILTER: To prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion
