1. Input connections: Connect with quality patch cords from the head unit,
preamplifier, crossover, or any other sound processor.
2. Input level: This is NOT a volume control. The input sensitivity should be
adjusted to give you maximum output power while minimizing distortion. To set
the input sensitivity, first turn the amp input level control fully counterclockwise.
Turn the source output level up until the signal just starts to distort, and then turn
the source back down slightly so that the distortion goes away. Now rotate the
input level control on the amp clockwise until the signal just starts to distort, then
turn the amp input level control back down slightly so that the distortion goes
away. This setup procedure allows the source and amp to reach maximum clean
output at the same time. For maximum performance/power, the input voltage to
the amplifier should not exceed 6.5 V rms.
3. Speaker connections: These connections are high quality 5-way binding
posts. You may connect them with banana plugs, spade connectors, pins or bare
wire. For stereo connection of the amplifier, connect the positive speaker leads to
the red posts and the negative speaker leads to the black posts. For mono
connection of the amplifier, connect the speaker positive (+) to the left, red
binding post and the speaker negative (-) to the right, black binding post. The
amplifier is capable of being connected in mono and stereo at the same time, but
a passive crossover should be used.

ohm stereo or 4-ohm mono. Unlike most car audio amplifiers, the DPS500

designed for maximum power output into BOTH 4-ohm and 2-ohm stereo loads,
as well as 4-ohm mono. The DPS500

inside the amplifier. First, remove the faceplate with the status indicators and
slide off the bottom cover. You will see two, plug-on wires directly between the
status indicators and the power connector. Move both of these wires from the
positions marked '4' to the positions marked '2' on the circuit board for 2-ohm
stereo or 4-ohm mono operation. After making this change, you should readjust
the input level control as in (2) above.
5. +12V connection: Connect 8 AWG or larger power cable through an inline
fuse to the positive (+) terminal on the battery. Position the inline fuse within 18"
of the battery. The inline fuse should be the same style and rating as the fuse on
the amplifier. Be sure all connections are secure.
6. Ground Connection: Connect 8 AWG or larger power cable directly to a
clean bare metal surface on the car chassis. Use as short a cable run as
possible. Be sure all connections are secure.
