I pulled the system out of my 05 F150 (2 Kicker L5s, Infinity comps, PowerAcoustik LT480 for front stage, and Kenwood Excelon XXV-03A for subs, 0/1 ga wire). That Kenwood and those Kickers really knocked, but that F150 is soo much more solidly build, don't have to worry about rattling like I'm sure the Mustang will. This is the first time I will be setting up a system in a Mustang, any suggestions? I will be ripping the Mach system out, any problems loading aftermarket tweeters in stock locations?
