Sundown Audio SIA 3500D Amplifier

Experience the next evolution of high-performance car audio with the Sundown Audio SIA-3500.1D. As part of Sundown’s latest flagship lineup, this intelligent full-bridge amplifier is engineered to deliver massive, efficient power without compromising on reliability.

    Amazing

    I ordered this amp over 3 years ago and it has been a beast. I run it straight to 2 15’s and it does not disappoint. Very fast delivery and perfect condition.
