The stock speakers in the 2015 Sierra are typically rated for 20 to 30 watts, which are quickly overwhelmed by the clean power output of a modern amplifier. Choosing the Right Head Unit for Modern Driving The heart of any stereo upgrade is the new head unit, and selecting the right one ensures compatibility with current smartphone technology.
