Hi, Thanks. Yes, I think so too. But I've no idea what or why I need an LOC and how to go about making the connection. I'm hoping the harness will solve my problem. I can't PM Technic yet until I have a sufficient number of posts. Technic has replied to another post of mine. So I'll follow up with him on that. I was hoping BSW would eventually come up with the amp upgrade, but from other posts, I think that may not happen soon. With my current set up, having only changed the door and rear speakers to the BSW, there's too much of a boomy mid bass. Don't know what to do. I wonder if anyone else has had this problem. Once I get Jason's spacers, I'll put in the SWS8s and see if there's a change.
