The Alpha One BMW Speaker Upgrade is a true Plug and Play upgrade that offers studio quality sound and takes just a few hours to complete. If you're interested in increasing the clarity, power, and bass over your standard Hi-Fi system, look no further. It replaces every speaker in your vehicle, from the midrange speakers, tweeters, down to the woofers under the seats. This system was specifically designed for BMW's acoustics and mounting locations, so the audio is perfectly balanced and tuned. This is a great DIY that only takes a couple hours, with the majority of the time being devoted to trim removal and replacement.

In the past, consumers were forced to use generic products and make due with what was available. The folks over at BimmerTech recognized this shortcoming, and developed a speaker system that was not only easy to install, but also acoustically sound. This is a proper speaker upgrade for your luxurious BMW.
