Im running off the stock headunit actually. No amps or anything besides the speakers. Have the sub box Candyman donated to me but its a pretty paper weight for the moment.
I plan on getting a Kenwood KDC-993 as a headunit though and probably a profile amp.
The location of the front tweets is a really common way of doing it actually but it sounds really nice from there =)
I sat in the rear of the car and held the tweets in different places before I decided to put them where I did.
