Is the Alpine Upgrade Kit for the 328xi Coupe available in the United States?

I have the 10 speaker configuration, but not Logic 7 in my new 328xi Coupe I just purchased, but my previous 335i Sedan had the Logic 7 and I was very much attached to it.

Is there a better option for cheaper or just as cheap?

I really enjoyed the bass and quality of the logic 7 after I fine tuned the DSP.

Actually, all I think I want is the Alpine Upgrade's Amplifier and wiring so I can wire the Subwoofers to the Rear channel on it and use them independently from the stock rear speaker channel.

Even if it would be available in the USA it is not applicable to your 10-speaker system.

You can replace the OEM amp with any mid power (less than 100W RMS power per channel) 6-channel aftermarket amp while keeping the OEM speakers, though.

I see, now would an aftermarket AMP allow me to dedicate a channel to the underseat subwoofers? Or are they already on their own channel in the 10 speaker set up?

Forgive me, I'm not familiar with BMW's speaker set ups aside from the Logic 7, and it seems to be quite confusing.

6 channels amp will drive fronts (2 channles), rears (2 channels) and underseat woofers (2 channels) individually.
