Down4Sound provides a limited warranty on their products purchased directly from their site or an authorized dealer. Note that the warranty does not cover damage resulting from improper installation.
First, check your power, ground, and remote wire connections. Ensure your speaker impedance load doesn't exceed the minimum working impedance (e.g., 1 ohm for a single standard JP series unit or 2 ohms strapped), and verify your vehicle's electrical system can support the amplifier's current draw.
