Hello all, I'm new to this forum and have several questions that someone out there can answer. I'm interested in 6.5 components speakers and out here many dealers sell products I never heard of. Has anyone heard of Diamond Audio, Fusion, Arc audio, Solid. I have a 04 dakota club cab and my headunit is Sony F7700, Polk dx6 brand new from my previous car. I was looking at Fusion FJL-65C, can someone please give me some information.
