(Nevermind the messy cargo area)
I had the Rockford Fosgate P300-12 in my last car (
Sportage), but it wouldn't fit/conceal well in the Telly. So I went with the P300-8 so I could place it in the storage compartment. It's a single amp/sub unit, and doesn't need a remote wire. It powers on when it detects the RCA input, so it was one less wire to splice into or run through the car.
I grabbed the RCA inputs from the kick panels noted/pictured from previous posts, and ran all wires (power, RCA, and controller) through the driver side kick panels, then through the storage area for the jack.
For a single 8, it's surprisingly loud. Will have to play with the settings a bit to tune it out, but well worth the time and effort.
