I Ron Laraba, recently purchased a used boat in Florida, with a JL Radio Head Unit MediaMaster 100s, which I did not know how to set it up. A good friend recommended JL Audio. I personally spoke to Louie the owner who stated he would order software updates which were needed. Within days he came over, did what he knows best, fixed it and showed me how to operate it. I am very happy with the outcome and I would highly recommend this company as their expertise is exceptional. Thank you Louie.
