Im getting ready to order the sub and now I need the harness. Now i have only had my truck for about a week so i dont know too much about it still. I know I have the JBL H/U. Its not the 6 disc type, just the standard JBL system. Its def. JBL. So when ordering the harness it asks if u have the standard system or the JBL premium H/U. Its the whole "premium" word thats throwing me off. Sorry Im an idiot, could someone clear that up for me?
