2019-2023 Subaru Forester Harman Kardon Audio Amplifier Amp OEM 86221SJ012

The 86221SJ012 is the high-fidelity Harman Kardon Power Amplifier found in the "facelift" 5th Generation Subaru Forester. Because this amp controls the entire multi-speaker premium sound system, it is a high-ticket item—dealers often charge $950+ for a new unit.

This part is the "updated" version that replaces several older, failure-prone part numbers, making it a very desirable "fix" for owners experiencing audio blackouts or popping sounds.
