Ok here’s some pictures.

Let me know if you have any other questions. Of note my wife’s x5 has the logic 7 system.

This just shows how I routed the wires to the Loc.

Thank you so much !!


I have the S677a HiFi System Professional DSP
My X5 50i was made 06-10, are any of these components HK?

Send any email to Technic and see if he makes a harness to add a sub. I'm sure he does.

I don't understand? (just sent you a PM) thanks :)

Do you have a center chanel in the dash? Tweeters everywhere including the rear area? Full graphic equalizer thru idrive? If you said yes to all these then you have the Top Hi-Fi system, or aka logic 7.

Thanks Maniac, but I figured that out 3 posts ago thanks to Matt.
Is this a HK system, speakers, subs, amp ??

(is it worth upgrading speakers or subs) ??

You can always upgrade the speakers but you’re limited by the power output of the logic 7 amp.

To add a sub you have to do what I did in the pictures. That’s what I though this thread was all about. You can always upgrade to a better sub. The stock
Subs are better at mid bass than sub bass.

If u wanted to upgrade all the speakers without changing the amp, audiofrog speakers are pretty sensitive and would probably do ok with the stock amp. Bavsound makes upgrade kits tailored to the stock amp as well.

This is what you’d be up against to just replace the speakers if u don’t go the bavsound route.

I had other questions, but not even a courtesy "no thanks" :(
