i am going to purchase a sound system for my new ford escape. i am thinking of going with the alpine d310 head unit, focal component 130A speakers, an alpine amp (don't know which one yet, i am going to keep the stock rear speakers, and get an MTX sub 12'. do you think this is a good setup. i listen to mainly rock music like U2 and The Rolling Stones, but i also listen to some rap and hip-hop.
