First off, brand new to the forum and a proud owner of a 2007 edge sel plus as of yesterday. I'm very suprised on how poor the audio quality is. I traded in a 2008 base model dodge charger and the stock sound system (4 speakers) blew this one out of the park.
My edge does not have the factory subwoofer so I imagine it's a 4 speaker setup as well. It does have the navigation head unit. Any updates that I can do aside from throwing a $500 sub box in the back for better lows and mids?
In the past, when I just replace the door speakers, I only get improved trebble. Maybe it's the insides of the doors that don't help with the sound quality? I don't know. Any advice is greatly appreciated.
