Alright, so my girlfriend's amp keeps becoming disconnected, and i am planning on mounting the amp to the seat to avoid any further complications. I've always done custom installs so i don't know what kind of screws to use for this.
she has a saturn ion 3 and there's thin sheet metal behind the fabric on the trunk side. routing wires won't be an issue, the only thing i forsee happening is the amp will fall off the seat when she goes to put it down to store crap. The amp in question is an Alpine MRP-M450. The screws are What's the best kind of screw to use for such an install?
(I'm trying to avoid making any kind of custom MDF panel to mount the amp to, i just want to screw it in and forget about it until it needs to come back out. She doesn't really care about that kind of aesthetic property like I do.)
