Has anyone purchased and had Best Buy install any of their car audio stuff? Im looking for an Mp3 head unit, amp, subs, speakers.. The whole combo, but I don't want anything ridiculous so it makes it sound like my trunk lid is gonna blow off. I mostly listen to rock music anyways, so having a tremendous amount of bass doesnt matter to me I just want something that sounds good. Wondering if anyone knows if the Rockford Fosgate punch series is any good? How are their prices? I am just curious, we have alot of car audio shops in my town but they all always wanna set me up with some competition level crap and im not looking to spend $2,500..
