Securing A Sub - Ideas?

[predator]

I've got a 12" sub in the back on my R32.. but its' giving me the royal shits.. as the damn thing keeps sliding around and bunching up the carpet, and I end up finding it at all sides of the boot... and it ends up ripping its wires out from the amp. So i've actually taken it out as I had enough, and something was just going to get majorly damaged eventually.

Now the solution could be to stop driving like a mad person, but as we know, that's not going to happen.

so - how do most people secure a standard subbox to the boot of an r32?

I am not sure the best way to do it.. I was thinking of a strap or something, but secured to where?

The must be a fairly standard way to secure them to the boot, more specifically any pointers on an R32 gts-t ?

haha...i have an r33 with the same problem.....wat u can do is be smart and buy some corner brackets (those 90 degree thingos from bunnings) and jus screw it in2 ur floor....ordo wat i do...backseat...and belt it up.hahahaha

hey,

i went to a hardware store and bought a strap with one of those little clips that you can push on and pull the strap tight. on my 34 i was able to thread it down behind the back edge of the carpet and the through some of the metal structure of the boot floor and back out over the top of the sub box. also makes it easy to take the box out if you're going to the track or need to get at your spare.

my car doesn't have the bit of wood stuff for the boot floor but the other option is to get one made one up and screw the box onto that. the sub still might go flying as you pull -1G getting air though.

lots of velcro underneath it might stick it to the carpet as well

doesnt matter if its stuck to the carpet because the whole carpet will move...

[BreathLess]

The elbow joiner is probly the easiest way to do it and doesnt cost heaps.

Heh.

I've got a rear strut brace so i just use an adjustable strap (eg like you would use for tying something down to roof racks) to hold my box in place. The box is black carpet so you can hardly see it

I found a bolt welded to the underside of the parcel tray support. Bolted a bracket made from flat aluminium 40mm x 2.5mm that goes across to the box and down to a mounting point on the side then another bracket was made with the same stuff. It was L shaped. The bottom part of the L goes parallel to the floor and you take out one of the rubber bungs and put a bolt through to another flat piece of aluminium.

You then cut a slit in the carpet which can't be seen when you remove the bracket and the side of the L shape goes up through that to the same mounting point on the side of the box.

This is a really solid mounting which is totally removable. I could go to a track day with it in I'm that confidant of it's strength. The only left over thing if you remove it is a slit in the carpet which you can't even see.

velcro wouldn't be the best, as the problem is the whole carpet moves.. I build an aftermarket mdf floor, so its a bit slipperier than the old piece of cardboard stuff..

Abobob I think has what I was leaning towards... will try some of those ideas soon. Strut brace could make it a lot easier, but don't have one of them.

It's just stupid when it flies around like that.. doesn't even require that much, as the tail always gets the most amount of momentum and anything inside just slides back and forward.

i have a mdf floor real easy to make then u just get some "L-shaped" brackets and screw them to the sub box then screw it to the floor

no more floating sub box

ever heard of ROK STRAPS? $13 and they clip it into place.

do a google on it and if you like what you see - then PM me.

get a 15" and it fits in perfectly thats what i did lol

[Abo Bob]

No offense intended to you or anyone else but I think putting 15" subbies in cars is one of the stupidest ideas out there.

Eg; a average kick drum sound has most of it's energy at around 63Hz. A 63Hz sound wave takes 16 feet to travel one cycle. So unless you are 16 feet away from the speaker or more, a very large proportion of the awesome output of a 15" subbie is completely wasted on you.

All you can hear in the car is reflected waves.

This explains why people on the street can hear perfectly the sub bass created (and the number plate rattling) but the idiot in the car doesn't even think it's turned up that loud.

[syx]

well said

[ronald_r32]

well i had a 12" in there and was not loud enough. Now i have a type r 15" and it is extremely loud. I think it does a great job and am very happy i bought it.

[Abo Bob]

That's what counts. :):)

Please don't screw it into your floor.. I think that's the fuel tank

I've got a rear strut brace, what I've done is bought some cargo looking strap things for $20 from super cheap auto. They are the ones that are flat tape with a lever on the end so you feed the tape through and make it tight with the lever.

I used them both to secure the sub to the brace and it ain't goin nowhere but is still removable for the track etc.

Otherwise mounting brackets into your seats or something - just make sure you don't use a screw too long to stab your passengers, or too short so it falls out.

Good luck.

use a screw too long to stab your passengers

<{POST_SNAPBACK}>

hehe passengers don't like being stabbed...

[dangerous_daveo]

I put some velcrow on the base of the sub. And the that to the carpet. Then lifted up the carpet, and put some of that grippy sheet stuff, simliar to the stuff you use to open hard to open jar lids. As my sub covers my jack this makes it heaps easy to move. As I just lift up the sub, yet it doesnt move unless I pick it up.

Try it anyway.

[predator]

velcro could even be enough, true..

Please don't screw it into your floor.. I think that's the fuel tank tongue.gif

yeah, not a good idea.. anyhow, I have worked out what I'm going to do.. Buy some rears, use my old 2 channel I have had sitting there for 2 years doing nothing.

I've built a basic replacement wheel well cover using MDF. Will just make a new one a bit larger (mmm, jigsaw) more in the size of the carpet shape, and screw both my amps to that...

Then use a couple of _| brackets to screw into that, and hold the sub in place at two diagonals. To remove, I simply lift up the sub and over the brackets (and hopefully I won't be getting the car airborn too often ). This method the carpet will be held in place by the amp screwed to the MDF below. I can also run the cabling a bit later under the carpet, and do a few small holes for it the cables to pop up near the amps, subs, etc so its not spagetti city.
