Hi All,

I have 2017 X1 with Hi-Fi. I've been thinking to upgrade.

There are couple of junk yards where I live, I stopped by there to see what I can get from old BMWs to make my audio system better.

Those are the models below that I can remove speakers and amplifier from

E90 3 series Harman Kardon
2005 5 series Harman Kardon
2008 7 series Harman Kardon or other high level brand

I wonder which amplifier should be compatible with - like plug and play?

All BMWs mostly use 4" speakers, I don't think it won't be a problem.

Speakers are $25 each.

Which speakers from models above would you recommend me to get?

Thanks!
