The third-generation Acura TL, spanning the years 2004–2005, 2006–2007, and 2008, comes equipped with a factory amplifier located in the passenger kick panel. The factory audio system in the Acura TL consists of 8 individual drivers, including the front speakers, the dashboard tweeters, the rear deck speakers, the subwoofer, and lastly, the center channel speaker. When the factory amplifier is working with no issues, the factory audio system sounds rich and full. When your amplifier begins to fail or has failed, the system sounds tinny, and the volume output is very low. If you want to upgrade your sound system or if your factory amplifier has failed, this is a great option to consider. Our plug-and-play amplifier works with the factory radio or with an aftermarket radio if installed with our accessories. The plug-and-play amplifier will work with your factory speakers or aftermarket speakers. This is a five-channel amplifier that will retain all your speakers except for the center dashboard speaker.
