Connect speaker wires observing
polarity. The minimum impedance
load for the AXA20 and AXA40D
is 2 ohms stereo and 4 ohms
bridged. Use of loads lower than
these is not recommended and
may cause amplifier damage. The
AXA20 and AXA40D 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)
CAUTION
Do not use both low and high level inputs at the
same time - connect only one or the other.

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) may or
may not require a connection to
chassis ground - depending on your
particular installation.
