Switch Pod Alternative

I would worry about hitting that stuff, but as long as you tie it into your ignition, it shouldn't matter too much.

I went with the SP-9100 for everything but maybe my planned lockers and air compressor (still haven't decided).
 
I have yet to hit that speaker with any part of my body.
Roll bar? With my head, a lot.
 
I tend to drive with my knees very close to the dash. However I think it probably is gonna be clear there, because in my truck I've got a brake controller and I only barely touch it on rare occasions.
