Hi Everyone,
I have a JL Audio 10in sub and Class D full range HD Amp that was custom fit for my 550. I sold the car for a 2015 M3 so I am looking to sell the Amp and Sub. I had the B&O entertainment system in the 550 and it sounded unreal with the sub. It's a very clean box and still gives you plenty of room in the trunk. Let me know if anyone is interested.
Thanks!
