I am putting in a second amp in my 06' LSV I have one under the glovebox area that faces towards the opening against the back wall above the battery. I was thinking about putting the other one against the left side facing in where there seems to be a little bump. I am not sure what is behing it. Is it a vent area looks like tubes coming out of the top of it. Could I drill into that or not? Any thoughts on where to mount another amp?
