I am updrading my pontoon audio. I need a new deck that can run 6 6.5 inch speakers. Also looking for with a speaker pod witha tilted wedge to them. I currently have rear pop up speakers from premier marine that dont sound very good. since the new rear speakers need to be top mounted, i am looking for something with some angle to them to point them somewhat forward. Any help anyone? also will I need an amp? current stock stereo has ran the 6 without but doesnt have bluetooth.
