Versatility Meets Clarity. The LAD100.4 is your go-to solution for adding clean, controlled power across your mids and highs.

This amp runs cool and clean — and with its compact chassis, it fits just about anywhere.

The Hydra Series amps don’t cut corners. This model includes adjustable high and low pass filters on all four channels, a full-range passthrough option, and high-level input capability to simplify factory integration.
