subs mounted... steel inclosure?

[ccandr]

Have a car currently being built , has an area behind the back seat that would be perfect for subs. This area is sealed but dont know the volume. Really looking for advice on mounting subs to metal structures or enclosures...any kind of special instalation tricks? or would this not be a good idea? kinda limited on space...

thanks for any and all info

a steel, or metal enclosure would resonate WAYYYYY too much to be any good for subs, not to mention it would weigh a ton..

Not a good idea. Why do you think EVERYONE uses MDF, even on ultra-premium installs?

I've seen it done, but it's tough to get it to sound good because of the resonance of the steel. I've never built one personally, but I'd imagine a simple square enclosure would be 6 sides of steel welded together. Maybe deaden the inside of the enclosure with Dynamat/Raammat/etc, as well as the exterior if you plan on carpeting it or wrapping it in something. Other than that, not sure what other suggestions I'd have.

hm.. might have some weird resonances.. i'd suggest damping the inside of it well, and have it thick enough it wont flex.

not building an enclosure out of it ... it is already part of the car ...no added weight

looks like you dont care what we have to say.

You already cut the holes.

if your gonna keep it like that, deaden the hell out of the inside of that enclosure and put some bracing in there

i would spend no less than 12 hours actual work time deadening that enclosure.. and bracing it.. it looks like it's just sheet metal

Cut out the metal and make your own enclosure out of mdf. Your making it so complicated and retarded.

You sound like my parents. Ha.

Anyways, *IF* those holes were made for the subs, then you might as well follow through. However, deadening is a must, whether liquid or mat. In fact, if you're not on any sort of budget, i would go ahead and deaden the entire car while you have it in that stage. Its a day and night difference when deadening is installed properly.

He would spend alot less time cutting out the metal and making a mdf box

thanks guys for all the advice, just trying to make the best of the situation

it's braced good, can stand on it...16ga top and front

thats gonna flex and resonate like a mofugga, no matter how much bracing... thats only body steel...

You might as well not ask if your going to keep on doing it. IT IS NOT RECOMENDED!!!
