Gus,

My dealer as well screwed up installing the second battery, Perko, and towers I negociated in with the sale. Not in the Perko, but rather they had it wired so that there was so much noise that I could not even idle the boat with the radio on. They had my boat for 5 days and made it worse. I took it to Earmark Marine 3 hrs away for a custom system (see my post). David is very big on not over engineering a system when it's not needed. Even with my system, David pretty much insisted that the Perko is all pretty much everyone needs in simple to highend systems. Plus, whether in person or over the phone, I like the way David can "dumb it down" for us mortals to understand.
