My car(2003 Malibu) is stock right now, but I have two old school Rockford Fosgate Punch 12 inch woofer's in a kicker box and a lil kicker small wattage amp to drive them. Never have the time no more for my car(poor baby).
Eclipse is some great stuff, they have just about the best head units out there(least they used to). But I've always just went with the alternatives after seeing there prices too.
My old boss could take a sixty watt amp use some caps, and cross over build a hole system around it. And have some pretty good BD"S to boot, he taught me a lot!
Right now I'm putting all my time in to computer lately, guess I'm just getting older
, Don't get me wrong I love high end
And quality sound too!
