2010 BMW 1 Series Audio Upgrade
After upgrading the front speakers in this BMW at our headquarters in Sheffield to a set of Rainbow BMW specific 3 way speakers, we then added a JL Audio XD700/5 5 channel amplifier to drive the front end bi-active with the addition of a Hertz EBX-F25.5 10″ subwoofer. This improved the sound no end and the customer was over the moon.
