Imagine audio in your BMW so crystal clear in every detail, so powerful you can't come close to maximum volume, so alive that when you close your eyes, you'd swear you're at a concert.

Now imagine it takes just 30 minutes to install, and you have the BSW Plug and Play Amplifier Upgrade.

In another industry first, we've developed an amplifier upgrade that's a direct plug and play install and optimized for your exact model BMW equipped with our Stage 1 Audio Upgrade. (This upgrade is not compatible with factory BMW speakers).

So what exactly does this upgrade mean in terms of improved audio performance?

• A clean signal so your enjoy your music in its full recorded glory: We've reduced the level of distortion our amplifier introduces to the audio signal by an average of 90% versus the factory amplifier (~10% THD vs. < 1% THD). We'd compare the difference to going from FM Radio to a CD.
  
  
• Much higher, distortion free volume limits so you can really rock out: By increasing power per channel from an average of 300% - 500% (~10-15 Watts RMS vs 50 Watts RMS), we've made your audio system capable of playing LOUDER without giving up even the tiniest bit of clarity or accuracy.
  
  
• More "lifelike" reproduction of music. So real, in fact, don't be surprised if you tear up. Because our amplifier is so much more powerful and has a significantly higher dampening factor than stock, the movements of your BMW's speakers are more accurately and tightly controlled, yielding lush details, more impactful midbass, balanced midrange, and nuanced highs like you've probably never experienced.

How does it install? Simply.

Your factory amplifier is completely removed. Depending on your vehicle's configuration, the amplifier will go directly where your factory amplifier went or be hidden in another convenient location in the trunk. We include a vehicle specific plug and play harness to connect the amplifier to the vehicle's audio system and required power and ground wires. It's so easy, even a total novice can do it.

Total install time: 30 minutes - 1 hour. Total pleasure: immeasurable.

Hard to believe? Don't. Try it for yourself, risk-free.
