I'm running the Alpine PDX-M6 with the Type-R 12" sub in the Fox box and it is perfect for my needs.
The sub is 600RMS max and the amp is 600 watt RMS so it was a perfect fit. I would love to get rid of the factory Head Unit and replace with aftermarket... Like the $1,500 one we talked about Dave
So that I can tweak the sound way more than with the stock settings.
I still need to rip out all the door speakers, tweats and roof speakers and replace with better speakers but....... I have a $2,700 product that i'm saving up for
