Guys, its me again, lol asking another newbie quesion
This time, its about how best to secure my sub to my boot. I dont want to go making a custom floor, and i believe that the fuel tank is located behind the spare. From what i have read, velcro works a treat
Any ideas ?
Cheers

velcro will stop your box moving around
i've got some elastic ties that also hold the box down
just little things to slow people down when trying to steal my sub :)
angle brackets would be good too
dont use velcro, if you get in a crash, itll do nothing :P you can but proper tie down straps that are used to secure down boxes, they sure dont make it look all that great, but its a lot better than having a sub decimate hyour bodywork when someone rear ends you :P

If your gonna screw it down or bolt it just make sure that you remove the spare tyre.
May think that nobody could be so stupid and drill into their spare tyre but it did happen, to my mate.
My sub isnt attatched to the floor at all, just sitting there. Think i might velcro it today:D
velcro = bad. simple as that
I have a 2x 10" sub box against the back. It's secured by 2 1" wide flat bars that I cut and bent to shape. They're bolted to the box and then bolted onto the bolts for the baby restraints
That box is going nowhere....

I've got a single 12" in a custom box and it's the height of the box that holds it in place,It's a very very tight fit and has never moved.:D

I don't see how a subwoofer will decimate bodywork... especially in a rear end crash, I'd be more worried about the sub itself getting decimated along with the back of your car :confused:
My JBL 15" just sits there... its weight holds it to the sagging part of the boot over the tyre well.

mine is behind the driver side tailight, and theres 2x large bolts thru the floor of the box, coming out of the bottom of the car near the exhaust, all sealed up of course! definately not going anywhere!

I dare say that a 20 - 30 kg sub travelling at 80 or so km/h could do some damage to the person sitting in the middle of the back seat.

Im confused, some say velcro is good, others say, its not so good :S. Also, if i drill in my boot, say, 50cm from the ski port will i drill into the fuel tank or anything, or is it just metal there ?
Funny thing is today, i picked my subbox up (minus the sub in it), and it didnt move at all. This was over a 40min trip. Fair enough i was driving quite calmly, but still :cool:
Thats why im inclined to think, some velcro, would probably do the trick
in my 2nd gen rada i screwed through my spare tire :( held it in well till i decided to take out the sub box and my spare went "Psooosh" lol

There is a rather solid metal wall behind the seats mate, then theres a fair load of foam. Plus if your sub was travelling that fast, so would the rest of the car, provided that someone isn't launching the sub box into the back of the seat with a cannon or something...

If I got into a crash serious enough to toss the sub so physically hard against the back of the seat that it would hurt someone i would be more worried about dieing due to the car crash :P

:stoopid: Think if the sub was goin to fly cause of a rear end id be worried more about the rest of the car crumbling onto me.
As for securing, i just lay byed a 12" JL Sub in Box, prob gonna use velcro or double sided tape lol

Before i screwed in my amps and sub, i had nothing but its own weight holding it down.
Lets just say, i ended up blowing up an 80A fuse. I think it was 80, 80 or 120 anyway. Reason.
The sub was thrown around pulling speaker wire out of the amps and in the end the power cable.... yes, nearly burnt mi car down.

Bolt the sub down. Use flat washers against the body to distribute the load, use split washers to reduce the risk of the nut loosening. Don't use cheesy bolts designed for garden furniture. Look all around the area where you are going to drill, if you can't see the other side of the panel, pick somewhere else. Make sure there is clearance to moving parts (tyre, axle, hoses, wiring etc) for the bolt. Angle iron can be used for brackets. The main hazards to avoid drilling through are the spare, the fuel tank, brake line and wiring.
Velcro is for trim.
The laws of physics also apply to sub boxes (namely momentum).
I wouldn't like to be punched in the back by a sub box in an accident. Although, I may not have the oppurtunity to sue, being dead and all.
