Im just curious how you are going to fit 2 15s and a front port firing forward in a 2008 focus trunk. The front opening was barely enough room for my 2 12s and 6" aero port to fit firing forward.
If the opening is close to the same size as 2004 the there’s no way your doing both firing forward plus port. I have a single 15 slot ported and there isn’t much room in that opening.
