Got a new headunit that let's you put your iPhone or iPod INSIDE the headunit. Also got a transom remote for it. Had to drill a 3.25" hole in the transom. That was fun with a Dremel tool!
I also got my sub in and installed my amp. The sub is a DVC alpine type S. I wired it in parallel to drop the impedance down to 2 ohms. The amp is a polk 5000.5.
