SAEv4-5000D

The SAEv4-5000D is a digital Class D monoblock for high-output bass systems, rated at 5000W at 1 ohm, 3300W at 2 ohms, and 2200W at 4 ohms. It is 1-ohm stable, so you can wire multiple subwoofers down to a single low-impedance load and use the full rating instead of settling for the 2-ohm number.

A dual MOS-FET PWM power supply feeds the output stage, and the recommended fuse rating of 2 x 250A tells you what kind of electrical system this amp expects. Plan on upgraded power and ground wire, and a battery setup that holds voltage between 10.5V and 15.5V under load.

Tuning is handled by a 12 dB per octave variable low pass filter from 40 Hz to 180 Hz and a 12 dB per octave variable subsonic filter from 10 Hz to 40 Hz, so you can set the handoff to your midbass and block content below box tuning. RCA input sensitivity reaches 6V max, which keeps noise low when paired with a high-voltage head unit or processor. Signal to noise ratio is 92 dB.

A four-way protection circuit watches thermal, voltage, speaker short, and DC-offset conditions. The wired remote control includes a clipping indicator, so you can set level from the driver seat and see when the amp is being pushed past clean output.

Dimensions are 18.5 by 6.30 by 2.75 inches, which fits a standard trunk amp rack or false floor.
