2008 e88 sound system upgrades

Hi all still fairly new to this forum and the 1 series I've recently brought but got some really good info from here on exhaust mods but now I'm looking to upgrade the speakers and wondering if I can add a amp to my original head unit as I would rather not change that if that possible
Any helpful advice would be much appreciated
Thanks in advance

Which version have you got?

Did you get the Bose upgrade from factory or just stock?

I think the question is Harmon Kardon, not Bose?

But the gist is correct, for starters, need to know what system you have. There are at least 3, maybe 4 options. There are some online resources to help w/ that. One of many examples here: https://musicarnw.com/start-here-your-car/

It's been 5 years since I did this, so forgive me if my memory is a little rusty.
  1. Technic PnP Harness. This allows you to install an amplifier in your trunk and utilize the existing factory speaker wires. No cutting, no splicing.
  2. Tweeter sails (L&R).
  3. I went with Morel component speakers. They sound pretty good.
  4. I can't remember what I used for the underseats, I can look that up.
  5. JL Audio 500/5.

If you haven't done anything already, I can look up the part numbers & such.
