Ok, try as I might, I cannot seem to fit the tank and regulator assembly on the shelf of the trunk. The gauges are simply too tall. I peeled the carpet back to help but still no dice. I thought about setting it up so the gauges were upside down, but then the solenoid hits. Naturally it fits with the gauges on an angle, but they're harder to read that way. I'd prefer to mount the tank in the middle of the shelf so I can put speaker boxes on either side. How did you guys end up mounting your setup? Any pictures would be helpful.
