I currnetly have a JBL MR-5 Marine Head Unit and have had problems with the display/faceplate and it changes volume and channels when I hit larger waves. I am about to get rid of it. I want some opinions of yall out there with different head units and yalls experiences with them. I am leaning towards a Sony, any experience with these? I have about a 200 dollar budget for the head and 100 dollars for the speakers. Thanks.
