So I'm starting to build a system in a 2015 Dodge grand caravan for the time being I'll be running 6x9's in the factory locations off a pioneer dmh-241ex head unit (50w x 4). I know eventually I'll probably add an amp for the 6x9s, but for now I just want to get a head unit, upgraded mids and highs and add a sub. After I hit the basics I'll start improving everything as I see fit and as the budget allows. I've got it narrowed down to either db drive 69s or ground zero gxrf 69al for the 6x9's. The 3 ohm impedance of the ground zeros is kind of appealing. I'll take advice especially if anyone has used these speakers personally with just a head unit power.
