hi, i have a 2001 mustang gt with the mach 460, and im thinkin about getting a new head unit, and i also want to get 1 12" alpine type r, i dont really know anything about audio but wut kind of amp would i need to run the alpine type r and do they make a wedged box or something so the 12" will fit in my trunk, also what are some good head units out there, and what other items would i need to get everything working right. thanks
