Question Subs in roof?

Has anyone seen an install with subs in the ceiling? I have a 2009 F150 with lots of headroom and a pair of 8 inch subs and I'm wondering if a custome fiberglass job up top will work better than under the back seat.

My main concern is safety - is there any way to do this without putting passengers at risk of getting a sub to the head in the event of an accident??

Thanks

as long as it's secure, it shouldn't be any more of a risk than any other part of the truck. I suppose you could use really strong epoxy to keep the enclosure glued to the metal directly. Once it's bonded to the metal, the enclosure won't move, and as long as the subs are mounted properly, they should be fine as well.

Seem like a potentially bad idea... u hit somthing big(or get hit) frame twists/bends everything connected to it follows suit(crumple zones) next thing u kno u got 15+ pd chunks of metal and magnet flying around thru the air. Its not like having it anywhere else in the truck... , its already up just waiting for that 1 push in another direction.
+ side curtains from top dunno if that has them but that could also make it interesting.

Not sayin not to do it just that i never would.

It's so unsafe because of the mentioned danger zones. You wouldn't even need a flip-over to get hit in the head by a magnet, just a swift turn or bump. A car-insurance person wouldn't give it the OK. If you want more than try the dash and doors, and try bucket seats so you have the console for space. You could also do a blow-through if you have a tonneau cover or a cap. A 10" between the seats would most likely outperform the two 8's, and by a large margin if the box is ported with plenty of power.

ever been in a transport truck, motor home, custom van or any large size recreation vehicle? They all have stuff mounted up high, including microwave ovens, toasters, cabinets, tvs, speakers, decks, etc...it's all in the install. If it's secure and properly installed, it'll be fine. I wouldn't be putting 160 oz magnet 8's up there, but normal 20-40 oz 8's will be fine. Obviously if you can put them in regular spots, that would be preferable, but sometimes you need to make sacrifices. Just google "winnebago interiors" and you'll see what I mean. Here's just one shot for example:

Holy crap! That's some nice work rolling around in those....

I would still be worried about headroom in the pickup cab tho....

I agree, I wouldn't do it myself, but if you want to get custom and do what needs to be done...no reason you can't do it safely. Personally if i wanted it, I would do a rollbar mounted set up bolted or welded to it, with light weight subs and mechanically bolt the subs to the rollbar and build the enclosure around it (fibreglass or whatever) so that the stress is placed on the roll bar and not the enclosure, and aim them away from the passenger compartment..maybe rear facing reflecting the sound off the rear window.
