BMW 328i Amplifiers

Refine Results

There's nothing like the feeling of heading down the road, listening to your favorite music, podcast, or talk radio. That's where the factory amplifier in your BMW 328i comes in. Without it, there'd be no way to, well, amplify the sound through your speakers. Yours is designed to provide the crystal clear audio that you expect. Unfortunately, sometimes even the best amplifier can begin to fail. Sound gets distorted, or suddenly there's no sound at all. You may even hear an odd chirping noise.

Choose the Best Amplifier for Your BMW 328i

If you start noticing problems with your audio system, your amplifier may well be the source of the trouble. Fortunately, replacing it is a snap. The amplifier is located in the trunk, at the left rear section. You'll need to remove the trunk paneling to access it, so make sure to take your time and keep track of the panel pins. When you choose an amplifier that's made at the factory, you can be sure that you're getting one designed to slip right into place and work immediately upon installation.
