This amp mount fits perfectly using the factory mount locations. It's still work in progress, but my test fit looks promising. Definitely space to mount other amps when in. In the Dodge, I would stay away from mounting amp in the center area near the seat belt, I plan on relocating that amp soon. As far as clearance from back seat, I will need to modify/cut the back wall carpet as it does touch the amps where I have them located, but I'll send other pics when the final assembly is done. Overall, great work on the mount!!!!
