So if I hear about an earthquake in SoCal I'll know your upgrades are done? Sounds like an amazing system. Congrats!
Just as an update, I've ordered the Pioneer comps for the doors, and Polk DB571's for the rear deck. It'll be the first time I've ordered without hearing them first,(Polks) but I've literally read hundreds of pages on various Mustang forums and have had a hard time finding complaints about them. So fingers crossed.
