WIRING

Fuse must be 
installed within 
18" of battery

Drill a hole in the firewall 
and use a rubber grommet
to keep wire from shorting.

Mount the DAC-348 near
the front of the vehicle to
minimize signal path lengths

Run the cables under the 
carpet near the side of the 
vehicle. Be careful not to 
drill or screw into the wires
when you replace the trim.

For systems over 300 watts,
add a ground cable from the
amp to the battery.

Run signal cables (RCAs) 
and remote turn-on lead 
down the opposite side of 
the vehicle from the power 
wire to avoid radiated noise.

Attach Ground Wires
firmly to solid metal.

Avoid sharp edges that 
could chafe through the 
insulation.

Factory Ground wire may

     NOTE

Before beginning, disconnect the negative (-) terminal of the
battery prior to working on the positive (+) terminal to prevent
a short to ground. This is important, unless you want to spend
the rest of your life with a nickname like 

"Sparky," or "Smokey."

Reconnect the negative terminal only after all connections have
been made.
