BimmerTech PP86DSP AMP/DSP

The world's best audio amplifier kit designed for BMW's

More power, clarity and customizable performance
BMW and Sound love

Every BMW deserves a great sound system

At BimmerTech, we love BMWs as much as you do. And we’ve made it our mission to enable you to quickly and easily upgrade and customize your car’s features with innovative products your BMW was meant to have. A fabulous sound system is one of them.

But until now, the only aftermarket options for upgrading your BMW system were generic audio products designed to fit any car. BMW is not just any car — so we worked closely with the great German audio manufacturer Audiotec Fischer to tailor one of their leading amplifiers just for BMWs. It’s an industry first — and you’re going to love the results!

If you’re into DIY, you’ll have it installed and working in about 60 minutes. Most of that time is needed to remove and replace the trim, since the amplifier itself is truly plug and play.

Premium Audio System or Speaker Upgrade?

Are you interested in upgrading your BMW audio system but not sure how to do it? Ideally, we recommend you upgrade the amplifier and speakers at the same time. But if you have a limited budget, a Premium Audio System will do more for you than a speaker upgrade for 3 simple reasons:

Dramatic improvement of every aspect of your BMW audio system

Clock icon

Easier and faster to install – no more than 60 minutes, instead of the few hours you would need for a speaker upgrade
