Vehicle-Specific Amp Bypass Harness

The Metra Electronics AXABH-LX2 is a direct-fit harness for the Lexus IS 300 produced from 2006 to 2009. It enables installers to bypass the factory amplifier when fitting an aftermarket head unit. The plug-and-play design avoids cutting or splicing the original vehicle wiring.

Factory Wiring Preservation

The harness uses 20 gauge conductors and measures 12 inches in length to reach the factory amplifier location. Its OEM-style connectors plug directly into the vehicle harness and the amplifier input. This approach keeps the factory loom intact for future restoration or resale.

Lexus IS 300 2006-2009 Compatibility

This part fits only the Lexus IS 300 for model years 2006 through 2009. It replaces the earlier AX-AB-LX2 reference. Vehicles outside this model range or those without a factory amplifier require a different integration solution.

Questions about this item

How does the AXABH-LX2 harness connect to the factory amplifier wiring in a Lexus IS 300?

The harness plugs directly into the factory amp connectors using its 20 gauge wires, letting you bypass the amplifier without cutting or splicing the original loom.

What physical space is required to route the 12 inch AXABH-LX2 harness behind the dashboard of a 2006-2009 Lexus IS 300?

The 12 inch length is designed to reach from the radio cavity to the factory amp location; ensure there is enough slack to avoid tension on the connectors after reassembly.

Many installers forget to disconnect the vehicle battery before unplugging the factory amplifier, which can trigger error codes or blow a fuse.
