XIA3145 INSTALLATION
Speaker Connections
Connect speaker wires observing polarity. The minimum impedance load is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XIA3145 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
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.
CAUTION: Do not use both low and high level inputs at the same time - connect only one or the other.
