Bimmertech AMP Upgrade

Every BMW deserves great sound

Until now, the only options for upgrading your BMW's amplifier were generic amps designed to fit any car. That meant complex wiring, tuning, and installation — and usually, poor performance.

But not anymore. Because your BMW isn't just any car, the BimmerTech Amplifier Upgrade was tailored for your exact BMW in partnership with renowned German audio manufacturer Audiotech Fischer. It's an industry first — and you're going to love the results.

Great Product

Awesome upgrade for Stage One speaker system with Ghost Subs. The mid/highs are crystal clear. The bass is tight.

I installed the amp myself in about an hour. No splicing, or soldering. It was simple plug and play. The equalizer allows you to fine tune your system to suit your needs. This is a product I recommend without ANY modification to your BMW

Major upgrade over stock

After adding the stage 1 speaker upgrade and the ghost woofers, my F30 sounded better than stock (hifi) but still underwhelming.

Adding the bimmertech amp made a noticeable difference, especially at medium to high volume settings. At low settings the sound is still a little thin, but after flipping a few DIP switches to up the output I am satisfied with the overall sound quality and volume. Still not a giant WOW factor or bass to knock you over, but a well balanced, clean sound.

Bimmertech PP82DSP Amp

Somewhat easy install for a person that's not very savvy when it comes to tech stuff.

My only issue is there is not enough info out on learning how to customize it yourself. Mainly because of the sound quality. I mean it's definitely an upgrade but it seems as if some adjustments need to be made. It's like the max performance comes from the center mid and you loose the ghost sub especially for a 900 hundred dollar pre programmed plug in pale Y. Overall I'm glad I upgraded but the sooner I can figure that bug out...ill be completely satisfied... Beamer guy for life.
