Recently, a car enthusiast brought us this BMW M4 for a custom stereo upgrade with Alpine Electronics. Our 12V audio tech’s built a box to perfectly fit a new 10″ subwoofer and amp in the trunk of this convertible sports car to sound perfect, never over powered.
All of the BMW’s stock Harmon/Kardon speakers were replaced with Alpine X series equipment in the doors and the tweeters next to the front windows.
