Coustic D-block Car Amplifier User Manual


 
INSTALLATION
Disconnect the ground at the vehicle battery before proceeding.
1. Connect the amplifier to the battery
For maximum amplifier performance, we suggest 4 gauge wire and a 1 Farad stiffening capacitor. A fuse
or circuit breaker is required at maximum distance of 18” from the battery to protect the battery, the
vehicle, and more importantly you (see chart below for proper fuse ratings). It is highly
recommended that installation be carried out by an authorized dealer.
2. Connect the amplifier remote turn-on
Connect the remote input terminal of the amplifier to the remote output terminal of the source unit (only
if using RCA inputs) to establish amplifier remote on/off through the power on/off of the source unit.
If the source unit does not provide a remote output, connect to a switched 12-volt source, e.g. ignition
switch.
3. Connect the amplifier ground to the vehicle chassis
For maximum amplifier performance we suggest 4 gauge wire. Find a solid piece of metal and scrape
the paint away where the ground will be attached (NO FACTORY BOLTS). Connect the ground cable to the
amplifier at this point.
- NOTE -
For optimum performance and
sound reproduction, prepare
and secure the ground
properly. Remove any surface
material before securing to
your chassis, ensuring a
metal-to-metal ground point.
