This 2010 BMW X5 E70 came to our Orlando showroom with the weakest factory audio available, the Base sound system, so Jarret had no choice but to give it a massive level up! See how he did replacing all the speakers and adding a powerful BMW amplifier upgrade.

The Base system comes with 2 weak and tiny BMW subwoofers, and 4 mid speakers, one in each door which are all powered by the head unit. Lacking a proper amp and tweeters, this system had to be upgraded with both a new BMW speaker set and an amplifier for a rich, mighty sound.
