Boot Ratle

[HussySV6]

Hey guys

I just got some subs fitted to my 2009 ve sv6 and the boot ratles like crazy.

I thought it was the number plate and drilled it but it hasnt changed in any way, when i OPEN the boot, the noise goes.

Any ideas?

Cheers

Really got fustrated with the ratle so i tryed to find out what it was, and i did.

were my spare tyre WAS ( under the boot) all the bolts and the flastics and the jack and etc was all there and they were vibrating like hell. Took them all out and no vibration.

Sorry guys.

dont you get the whole boot lid vibrating?

[revhead2011]

Dynamat is your friend!! get some to line your boot lid with, just about all vibration will go away. i run a 12" polk MOMO sub at 400w RMS and it rattled really bad before i got the Dynamat, but now there is no audible rattling at all

^^^^^^ Don't listen to this guy

[Nic92]

lol. ^, doesnt stop rattles..

[revhead2011]

um, would you like to come and listen? i dont hear any rattles!

ok then tell me how it works then..

Before i dynamated my front doors and boot lid, not only could i feel severe vibrations, but you could also hear the vibrations inside the car when the speakers/sub played certain frequencies. when the dynamat was applied it acts as a buffer, making it harder for particular frequencies to vibrate the door/boot skin to the point where it becomes so severe you can hear it over the music you are playing.
with my sound system i play a huge variety of music, i listen to rock, punk, electric, dance, metal, drum n bass, instrumental, vocals. Not just super wog DOOF DOOF out of an 18" sub that takes up my whole boot..

dynamt will have a different effect on everyone’s car because everyone has a different audio setup. with me it works fine because i have a moderately powered system that outputs good quality, not deafening levels of bass that create severe audible vibrations. the Dynamat does a good job at dampening those annoying audible vibrations that MY system creates.

also you have a sealed box right? so you wouldnt be producing low frequencies which causes the most vibrations..

What low frequencies are you talking about? Just shut up, you have no idea. Just because some people choose not to put their fully sick 18 inch into a ported box, doesn't mean it doesn't hit low frequency. Most subwoofers play below 40hz, which is low as it is...

[revhead2011]

i have a custom built and tuned ported box. its tuned between 32-35Hz cant remember exactly but 33Hz rings a bell. it was a while ago when it was installed. but it is definitely ported, i can easily put my fist into the box

[Nic92]

meh i give up

Back to the OP's issue. The best way to solve this is to crank the bass and work out which panels are vibrating. If you can apply some pressure to those panels and that stops them vibrating, then adding some dynamat (ie. mass) will benefit. Also I suggest putting some rubber stoppers behind your number plate, so it doesn't vibrate.

I stuffed my boot skin and siliconed the smaller gaps. No dynamat yet but there are no rattles. Only noise is the boot lid lifting up haha
Oh and with my plate I used 4 small roofing screws with double rubber washers on each one and put a whole roll of that door sealing rubber you get from bunnings behind it.

What did you stuff it with? I know of a lot of guys that have stuffed it with weather proof foam and have had great results.

I use heated duct insulation. I get heaps from work and it's really thick. Worked a treat in killin rattles.

Lol but he has an 18 inch sub in the boot so clearly he is an expert
