I have a 2009 Sundance XLT 287RL. Has anyone changed the radios out. Mine came with a Jensen AWM 910 and I have acquired a Jensen AWM 965. The 910 has a 12 pin plug and the 965 has a 20 pin plug. I know I am going to have to add 2 more speakers to the A channel and I wanted to know if any of you had done the above and if you had any problems with the install.
