what's goin on fellas?
I'm trying to add an amplifier and subwoofer to my harmon kardon system, in my 323i. I've heard they make a adapter where you can keep the hk system and just add the sub and amp to it, but i can't find the adapter any where. If you know where i can get one, and how much it cost then let me know. thanks

What year is your car?

Hi kaveh4d:

I found a "plug and Play" subwoofer kit dramatically improves the bass response and richness of you stock sound system. It cost $599.00 and includes a dash-mount remote control that lets you adjust bass level from inside the cockpit of you Bimmer. The companies name is: "BAVARIAN" AUTOSPORT and their website is: www.bavauto.com or try: http://www.bmwworld.com/audio/harmon_kardon.htm

I hope this can help you. :smile:

Sincerely an 04 530i owner, :smokin:
