David: Jason has a Pro Star 209, He has 2 Arc Audio Flatline 12's at the drivers foot well. Its a tight fit
2 12's will fit in that location it just requires alot of work to squeeze them into that tiny aera.
His fiberglass foot stop had to be cut out and removed and the floor re-glassed.
I installed 2 12's at the drivers foot well.
I had to remove lots of wires and re locate a bunch of stuff in the end it was /is all worth it.
