How to secure a sub enclosure
I'm interested to know what methods anyone can recommend for stopping a sub
enclosure from moving around in a boot/trunk without taking up too much space. TIA. |

$.20 metal "L" brackets at the local hardware store if its a medium to large
box... industrial strength velcro pads if its a relativily small encloser. Hope that helps DJ TecThreat The Real Threat "Kevin Scott" wrote in message ...

How to secure a sub enclosure proper styles
Don't sleep. Velcro, properly used, is a surprisingly effective fastener.
The heavy duty stuff has very strong adhesive and fabric - the weak point in your installation would be the adhesive, i.e.; the grip the Velcro has on the trunk surface. It is very difficult to shear a well engineered Velcro connection. You want to have the Velcro oriented so that failure would mean the box would "slide" the Velcro apart, not lift it apart.

How to secure a sub enclosure
In a previous install I used 3/8" dia carriage bolts, washers and bolt
it to the frame / unibody. Of course you have to drill a hole through the sheetmetal subfloor, crawl under the car and torque down the bolts from the under side. I used stainless hardware to avoid rust. Only way for that thing to clock me in an accident is if it were to rip the washers through the MDF.

You are probably right...I keep thinking of my install where the box is against the back seat and in an accident it wouldn't be 'flying' at the seat as it's against the seat. but if the box were loose in a larger trunk it would probably happen as you suggest. and if so much force was there, would 2 l brackets really preventi it? 2? maybe not... did i suggest using only 2? though two would be better than bungie cords any day i'd think... yeah probably need 4 heavy duty steel brackets at least not 2 cheap aluminum ones |

How to secure a sub enclosure
People!!! Don't use velcro and don't use bungee cords!!!
The sheer force involved in an accident or hard cornering/braking combined with a heavy sub box could easily overwhelm these "achoring" devices. Use some good, solid metal brackets or bolts and mount them securely to the trunk floor or wall...or both. Tony -- What's more likely? That an all-powerful mysterious god created the universe and then decided not to give any proof of his existence? Or, that he simply doesn't exist at all? And that we created him so that we wouldn't have to feel so small and alone. -Eleanor Arroway, Contact "sanitarium" wrote in message ...

Then there was the accident that one of the Seahawks was in, guy was
their running back as I recall... SUV went out of control in the rain, smashed into something hard (telephone pole or tree or somesuch) and the woofer box with a pair of 15's ended up crushing his buddy in the back seat. That's crushing, as in "to death"... JD seatbelts, big honking brackets holding down your sub box, and common sense should NOT be optional sancho wrote: "Z.

How to secure a sub enclosure
I thought about that, but since it is a hatchback and the seats have the
same type of fastening device as the doors they are well secured. You need a lot more than a push to fold tem forward without unlocking them. I don't think (at least I hope it will not) the box will get past the back seat on a collission. "sancho" wrote in message ... "Sonoman" wrote in message .. .

Unless you flip over a few times. I'm gonna fasten mine well in my hatchback after giving it some thought. Think about it. You flip the car over, the box comes out. Flip it over sideways after that and it's in your head. I'm not gonna risk it. |

You need a lot more than a push to fold tem forward without unlocking them. I don't think (at least I hope it will not) the box will get past the back seat on a collission. It will, easily. I'll bet that unless you're a weedy little runt, there's a good chance you'd be able to lie in the back of the car and break the seat backs just by kicking hard against them with your legs. Now, go here and read: http://www.vcu.edu/cppweb/tstc/kinetic.html They point out that forces of 40 to 50 G are routinely recorded during the standard 30 MPH crash tests. Your sub box weighs, for example, 50 pounds. Multiply that by 50: 50 x 50 = 2500 pounds. That's well over a ton. If you were to suspend your car nose down, then stack over a ton of weights onto the back of the seat, do you think the seat locks would hold? Would you be prepared to be buckled into the driver's seat while the weights were stacked? What do you think would happen to you if more than a ton of weights landed on you? It'd be ironic if you were to hit something, be saved by the seat belt and airbag, then be mashed to strawberry jam by your sub box. Bolt that sub box to the vehicle frame. NOW. It needs to be bolted down as securely as a trailer hitch would be mounted. This means high-tensile bolts and big load spreading washers. The bolts should run right through the box- it's no use just bolting the bottom down, the rest of the box will likely rip off it and go flying. If you doubt that, just take a sledge hammer to an old sub box sometime.(*) I'll wager that it'll only take one big swing to break out the bottom or a side if you hit it from the inside near one edge (puts the joint under maximum tension). The sledge head weighs 20 pounds or less and is moving less than 30 MPH. I'll bet your sub drivers weigh 20 pounds or more, and they will be moving faster in even a moderate collison. (*) Yes, I have done this. They were water and smoke damaged and had to be written off. We broke them up so they'd pack flat in the dumpster. -- Don Hills (dmhills at attglobaldotnet) Wellington, New Zealand |

Don't you all remember the story from driver's education about the tissue
box that was sitting on the rear parcel shelf? Some poor guy got hit in the back of the neck with it during a collision and it impacted against his spinal cord so hard it paralyzed him. Tony -- What's more likely? That an all-powerful mysterious god created the universe and then decided not to give any proof of his existence? Or, that he simply doesn't exist at all?
