Let me start off by saying I know nothing about car audio. When I got my car (2001 mustang gt) it had a kenwood deck and speakers, now I want to add a subwoofer but I don't know much about them. I would like to add Mach 1000 subs in the trunk with the factory enclosure but I can only find the whole system for $1000. so can any of you recommend a sub setup that is a bit more economical and won't render my trunk useless. Thank you
