The lake and Tank Trap where two different incides. I kinda forgot that my doors where off and got past the floor boards. I then heard a thump from my sub and looked back and my amp was in about a foot of watter. And I think the Tank Trap on is pretty self explanatory if you have see it. It probably didn't help that I was trying it with 30 psi and MTR's they don't like Hollister that much.
