Speaker Connections

Connect speaker wires

observing polarity. The

minimum impedance load for

the AX460D and AX490D is

2 ohms stereo and 2ohms

bridged. Use of loads lower than

these is not recommended and

may cause amplifier damage.

The AX460D and AX490D 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.

Note: Do not use both low and high level inputs

at the same time - connect only one or the other.

Typical speaker connections shown

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.
