OK to screw sub boxes/amps into back wall?

[NoOne]

For theft-prefention (or at least aggrivation) purposes, I was thinking about screwing my amps and sub boxes to the back wall of my reg. cab. Is there a reason I shouldnt do this? If I took them out I could always put rubber plugs or grommets in the holes to seal them......and them into the back of the sub box would make it pretty darn hard for a theif to make a quick getaway. Anyone else done this? What kind of screws did you use?

Do you have 2 boxes or just 1 big one? I had 1 long one in my reg cab and it was pretty hard to get out w/ teh subs in there. I'm not sure a thief could make a "quick" getaway w/ that, but if you wanted I guess you could screw them into the wall. I think I would screw them to the floor if I was gonna do it though.

You might wanna try the floor instead...the rear wall on our trucks is only single wall thickness. Unless you like the idea of the screws sticking out the back of your cab...

If you do screw into the floor, use a screw that is only about 1/2" longer than the thickness of the material the box is made of..that way you don't go too far thru and hit something vital. While thinking of that, check to see what's under the truck where you plan on screwing. Also, try and cut the carpet with a razor knife where the screws will go thru, scerws can snag the "knap" of the carpet and cause a runner or pull. I'd suggect a self tappind screw AFTER performing th above steps.

For my amp, I put a piece of MDF behind the back wall carpet and then used short zip screws (dry wall screws) to sandwich the amp, carpet & MDF together. I also put a black rolled up towel under the amp for support. All of this Houston heat hasn't made the carpet sag yet. I just didn't want to screw it to the back wall for rusting reasons.

Thats a pretty good idea - I might do that - how thick was the mdf that you put behind the carpet?

so the carpet is supporting the the wieght of the wood and the amps?? Hmmmm, that would mean that the whole assembly could move around

I used 1/2 inch MDF. I also covered it with some scap material so it wouldnt make noise against the back wall.

It doesn't really move around that much. I only have one amp. It is a 5channel alpine. I use the rolled up hand towel to help support the weight of the amp. I have the charcoal interior, so the black towel isn't that noticable. I didn't mount my sub box. It just sits on the jack cover and is held in place by the passenger seat.
