I am adding a set of speakers to the bow of my 2008 Tahoe Q5. I am wondering if someone has replaced their original MSX60SR Coaxial Jensen 6.5" speakers with a higher performing set. I would like to have a matching pair for the front of my boat and I am not to concerned with a high performance system. I'm interested in purchasing your old set for the right price. Would also appreciate any comments with regards to speakers and sound in your boats. The attached photo is what mine looks like.
