Speaker Connections
Connect speaker wires
observing polarity. The
minimum impedance load
for the AX4150D is 2 ohms
stereo and 2 ohms bridged.
Use of loads lower than these
is not recommended and may
cause amplifier damage. The
AX4150D 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)
Note: 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.
