Speaker Connections
Connect speaker wires
observing polarity. The minimum
impedance load for the AX260,
AX440, AX460 and AX490
is 2 ohms stereo and 4 ohms
bridged. Use of loads lower than
these is not recommended and
may cause amplifier damage.
The AX260, AX440, AX460 and
AX490 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.
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.

Note:
Do not use both low and high level inputs
at the same time - connect only one or the other.
High level inputs not available on AX3000M,
AX4000M and AX5000M..
