I've never had an amp die due to vibration. AND I drive drunk all the time. Like I said vibration may effect an audiobahn but out of probly 10 alpines mounted on a box none of them have die. But I agree the risk is there. Also if people would just bolt there speaker box down they wouldn't have to worry about anybody running away it. Most theives don't carry a battery drill and won't spend the time taking out 8-12 screws for a speaker.

Ok Since I'll just run an extra 3 feet of wire for each wire to the amp an just mount it on the back of the seat, at least with the extra wire I can fold my seat down when needed to haul something

I also never had an amp die because its mounted directly to the box, but I guess theres a first for everything

The only way to truly keep an amp from failing due to vibration would be to encase it in a force field or set it up to act as some sort of hover craft that only moves with an envelope of air and never bumps into anything. Regardless of where you mount an amp, it is going to be subjected to vibration. Your car vibrates with the engine running, doesn't it (I know this is minimal, but I'm trying to ilustrate my point, so bear with me)? True, mounting it directly to the sub box may cause it to fail prematurely, but if that is one of the only spots you have to mount it, I'd say go for it. As someone mentioned previously in this thread, most newer amps (I would like to think) would be made stout enough to handle such vibration, except in extreme cases of the box flexing/vibrating. And of course, since most of you advocate building custom enclosures and bracing heavily to reduce/eliminate said vibrations, then you should be even safer. A prefab box - that would be a tougher case. But I really don't see a problem with mounting directly to the box otherwise (except for the theft part mentioned, that really would suck!).

I vote for the back of the seat mounting. You can mount it low on the seat so that you don't have to have much extra slack in wire to fold the seat down. Kinda like this... https://www.the12volt.com/installbay/forum_posts.asp?tid=33362&KW=defective (look at the last pic)

Yeah that looks nice, thats what Im going to do, now I just need to get me some MDF and screw it into the seat frame and Im good, you think 5/8 MDF would be good enough or kick it up to 1 inch

Thanks
