XPA SERIES INSTALLATION .'
Amplifier Connections
Speaker Connections
Connect speaker wires observing
polarity. The
minimum impedance
load
for the XPA2500 and XPA4640
is 2
ohms stereo and 4 ohms
bridged. Use of loads
lower than
these is not recommended and
may cause amplifier damage.
The XPA2500 and
XPA4640 can
be wired for stereo. bridged or
stereo/bridged simultaneous
operation.

Input Signal Connections
Low Level Input (RCA)
Low level (RCA) input signal is preferred for best performance. 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.

Low Level Input
(RCA)
High Level Input (Speaker Wire)
High level inputs should only
be used when RCA outputs are
not available from the head unit.
Connect the head unit speaker
outputs
to the high level input
connector as shown below. The
black
wire (signal reference ground)
mayor may not require a connection
to chassis ground - depending on
your particular installation.
