SM-3600.1D

The Autotek SM-3600.1D is the highest output monoblock in the Street Machine Class D line, rated at 3600W maximum power and stable down to 1 ohm. It delivers 1 x 3600W at 1 ohm, 1 x 1800W at 2 ohms, and 1 x 900W at 4 ohms, so it scales from a single subwoofer to a multi-sub build wired low.

A fully adjustable 12dB low-pass crossover covers 40Hz to 300Hz, a subsonic filter runs 10Hz to 40Hz, and bass boost adds up to 12dB. The included wired bass remote mounts where you can reach it, so you set the low end from the driver seat instead of the amplifier.

QTD Technology adds mass to the aluminum heat sink for quick thermal dispersion, which keeps output steady when the amp runs hard for long stretches. Pro-Fi High Speed MOSFETs hold efficiency high and distortion low, and a high energy Pulse Width Modulated power supply moderates the demand on the vehicle electrical system.

RCA inputs with a low noise preamplifier circuit keep the signal path clean, with greater than 100dB signal-to-noise and 10Hz to 300Hz frequency response matched to subwoofer duty. Nickel-plated brass terminals accept 4 GA power and 8 GA speaker wire through screw-down connectors, and LED indicators report overload and speaker short protection. An external 125A fuse covers the current this amplifier can pull.
