Hi All,

First of all I'd like to introduce myself in my first post. My name is Dean Newman and I am 18 years old, I drive a 2000 TH Magna Exec (White) and I work for as a Customer Service Representative for Telstra Bigpond Technical Support in an outsourcing call centre in North Ryde, NSW 2113.

Now, the other night I just went nuts and decided to upgrade my existing sound system of 190w-doors/300w-rear to also incorporate an amplifier and subwoofer (Sony Xplod to match the existing, however couldnt afford the Xplod amp, so Kenwood it is!).

Anyways, everything is now up and running nicely pumping lots of bass and I'm loving annoying the old people (I live in the country town of Bargo in the NSW Southern Highlands so theres a lot of oldies to annoy around :)). However I have a slight problem with my bootlid making horrible vibration sounds, I have discovered the problem is occuring due to the plastic section on the bottom of the bootlid.

Long story short, I'm just wondering if anybody can give me some ideas on how to prevent the horrible vibration sounds that are occuring every time I play... well, anything!

someone else could help you, but deadening equipment problem is your best bet.

also my i say welcome!!!

Sound deadening is indeed your friend here. Any car audio place or JB HIFI sells it. Stick 1 or 2 layers on the underside of your boot lid and it should sort it out, but your boot will be damn heavy so don't drop it on your head!

And welcome :D

Ahh, so basicly get some deadening stuff for Jb Hi-Fi and stuff the gap between the interior and exterior of the bootlid with it?

Sorry if I got it wrong, I'm new with the car modding scene, master in the world of I.T. however :)

If you really want to deaden, do the bootlid, and all the inside panels of your boot (under the carpet) to really take the edge off the vibrations.

My sub set up is running at 50% or so, and the whole rear end shakes horribly (mind you, it is quite powerful gear..) I'll be at least double layering my whole boot when I do it, a bulk pack of dynamat costs about $300 something dollars, but you'll get clearer bass, and no vibration. Very much worth it.

or you could weld the boot shut:bowrofl: welcome dean mate have a good one matey

Use Dynamat to cover the boot floor, sides and lid.

This should reduce the amount of vibration from the back.

While you're at it, consider doing the doors as well.

Dynamat ain't cheap, but worth it....

JB sell Stinger and there isn't much difference and its cheaper if you are one a budget.

Any idea how much I am looking at, for either Dynamat or the Jb stuff?

Try this stuff $38 a sheet, 120x90cm.

I've been quoted $120 just to do the bootlid with Dynamat. Should take out a lot of the rattles.
BTW welcome to the club.

Cheers

A door kit of Stinger from JB Hifi is about $75 bucks. Be very careful (read "do not get") the cheap stuff as the glue is crap and melts in summer heat.
I would only use Stinger or Dynamat. Bit more expensive but you wont have to replace it every couple or years.

Also its very easy to do yourself... dont pay a fortune to get someone else to do it for you!

The Magna boot is a crap design. I had to fill the gap with carpet underlay and add a layer of G-spot over the top and foamed the number plate. Boot didn't rattle but the under carriage did. Gave up and got a new car :bowrofl:
