American International HWH81A 2008 Honda with RCA/SUB Input Wire Harness

The American International HWH81A is a plug-and-play amplifier integration harness specifically designed for 2008–2012 Honda vehicles equipped with a factory premium/amplified sound system (including models with factory navigation or subwoofer).
This harness lets you install an aftermarket head unit while keeping the factory amplifier and all factory speakers fully active — no bypassing the amp or running new speaker wires. It plugs directly into the vehicle’s factory radio connectors and provides standard EIA-color-coded power/ground wires plus the essential blue remote turn-on lead that powers the factory amplifier.
