Introducing Power Surge - Surge Audio's flagship series of high power amplifiers. These models were designed from the ground up, to be anything other than average. PS Series amplifiers feature a military-grade PCB with the most copper tracing possible, added standoffs for extreme vibration resistance, and overbuilt transformers to withstand the heaviest of abuse.

Cooling is key. The PS Series heatsink was custom tooled to optimize cooling capacity. We made use of thermal modeling to determine the best thermal conductivity of our heatsink options. Beyond that, we have spaced the mounting feet 1/4" below the heatsink to allow for additional airflow below the backplate of the amplifier.

All PS Series amplifiers include silver plated Tiffany style RCA inputs, four-stage intelligent protection circuitry, and a remote bass knob with clipping, voltage, and temperature indication.

    Awesome Amp

    Posted by Jason Dufrene on 6th Feb 2023

    I replaced my AW 5K with the PS7000.1 and it is a great upgrade. I have it pushing a DC Audio Level 6 18 and it really woke up the sub. I think these are the best bang for the buck. Excellent build quality and excellent customer support.

    Good value

    Posted by Charlie Diaz on 17th Aug 2022

    This has got to be one of the best bang for the buck amplifiers you can get. $999 for a half bridge korean amp is unheard of in this day & age. I really like it, I would put it up there with any of the top brands
