Where is the amplifier located in the LaCrosse
2 Answers
The amplifier of the LaCrosse is located inside the right trim panel of the trunk. The streamlined design of the 2022 Buick LaCrosse ensures aerodynamic advantages. Thanks to the newly designed body proportions, precisely optimized local shapes, and over 1,000 hours of testing and analysis. The longer and lower body is closer to the low-drag prototype, with carefully simulated and calculated grille openings, relative positions of the hood, front and rear windshield angles, etc., striving for smoother airflow paths. Combined with extensive wind tunnel testing, each surface of the body is optimized one by one, creating an aerodynamic shape with a drag coefficient of 0.29cd.
I drive a Buick LaCrosse and have specifically researched the amplifier location. Generally, standalone amplifiers are located in the trunk, but the exact position depends on the model year: For older LaCrosse models like 2006-2012, lift the trunk floor mat and you'll find a black metal box behind the left-side trim panel. For post-2013 models, some amplifiers are hidden behind the right-side trunk trim panel, requiring removal of the fabric interior panel to access. A few variants have the amplifier tucked under the front passenger seat - just pull back the seat rail weatherstrip to spot it. Important reminder: Always disconnect the battery before working. Those power and signal wire connectors are fragile, and forcing them can damage the pins. If unsure about the model year, simply measuring the trunk depth is the easiest approach - no need to flip seats.
