Yea in my truck it didn't really matter, it was loud and didn't move when going in circles or stopping. The interior on that thing is covered in gear oil anyway so what ever.
I've been thinking on ways to clean up my install for the new car which might not be done by Tuesday. Plan on running power and rca on different sides of the car to hopefully get rid of minor humming at low volume at takeoff.
Haven't decided where I'm going to mount my amps. I honestly have never been inside this car more than 5 seconds but I don't think the seats go down, just the middle hole thing. My sister bought this car last year and totaled it a month later so I'm fixing it out of my savings.
