Physical Mounting

When physically securing the unit to the vehicle you MUST ensure that the chassis of the
amplifier is isolated from vibration. The DB1.8 uses a sliding PCB design, which means that
the circuit board of the amplifier is held in place by the heat sink. This offers great stability
for such an enormous board but it means that all the vibration caused by your subwoofer
system will be transferred directly into the fragile PCB if you just bolt the amp to the floor of
the car. We recommend the use of some simple soft rubber feet, at least an inch tall, to
create a safe installation. Under NO circumstances can the DB1.8 be mounted directly to
the woofer enclosure! Cracked circuit boards are NOT covered under warranty.
