Hi there people. Just thought you might like to see this JL Audio Install i have done on this Focus. What we have is a set of 6.5inch components at the front and some 5.25inch co-axials in the rear all mounted on custom wooden baffles. In the boot there is 2 x 15inch subwoofers being powered off a 500 watt monoblock amplifier and the other amplifier running the front speakers. This system is loud and the bass hits hard. Drop me a email with any questions or requests. Hope you like it.
