Over the off season....(yes, it was unseasonably cold in Florida and we Floridians are spoiled) I installed new Rockford Fosgate tower speakers and added a new Clarion 750 watt amp to the factory Kicker system on my 09 Outback V. I also purchased 750s to replace the factory rear ballast bags for more weight. I think I read that I have buy new fittings and adjust the timing for the installation of the new bags. Is it very diffucult to do? What new fittings do I need? Thanks.

I'm really excited to get out on the water.
