Description

The Ampere Audio AA-3.0 18″ is the most torture tested subwoofers in the Ampere Audio lineup. The Ampere Audio AA-3.0 18″ was designed for 2000w rms per driver. The lead wires are formed into the spider layers which further enhances durability and eliminates lead slap/breakage problems. The frame is cast aluminum with a sandblasted, powder coat finish. One of the thickest 3” coils on the motor reduces energy storage from inductance, with the side benefit of lowering distortion for “faster” response.
