Amplifier Connections - Dual XPR510D Owner's Manual

Speaker Connections
Connect speaker wires observing polarity. The XPR510D is a 1 channel amplifier but has
two positive and two negative speaker terminals. When connecting one subwoofer, only
use one positive and one negative terminal. When connecting two subwoofers, connect
one subwoofer to each set of positive and negative terminals.
When connecting one
subwoofer, 2 ohms is the
minimum load. Dual voice
coil subwoofers that feature
two 4 ohm voice coils provide
an optimal match for the
XPR510D.
When connecting two
subwoofers, each subwoofer
should not have an ohm rating
below 4 ohms. Connecting one
subwoofer to each terminal
automatically sets the two
subwoofers in a parallel
connection.
Input Signal Connections
Typical trunk-mount amplifier installations require a 17-20 foot RCA cable. Most trucks
and under-seat applications require a 6-9 foot RCA cable. Using twisted pair construction
RCA cables will minimize noise.
