Padding for Bass enclosures

[DJ_Bucho]

I've recently purchased the Haynes/Max Power I.C.E Book, and I don't think its half bad.

It has some really good ideas in it and am at the moment concertrating on getting the 5 1/4" Kenwood 1387 speakers that I have installed in them to sound their best.

Please see other topic
https://www.fiatforum.com/forum/topic.asp?TOPIC_ID=7532

Having read most of the I.C.E book I was considering putting some sound padding /(whatever you call it) into the rear quarter panel area arround the wheel arch etc. The book says I can use Polyfill (NOT Polyfiller before anyone says) its comently used for stuffing quilts and soft toys etc.
Does anyone think this would improve the sound?

I've taken the rear quarter panel off and was basically thinking of filling the space behind it with the padding, but oviously leaving quite a large gap for the speaker.

I hope someone can shed some light on this subject.

Thanks a lot

Padding makes a speaker think an area is larger than it actually is, for example, putting a large sub in a small box, wouldn't sound at its best unless padding was used.
Filling that space isn't a bad idea, but padding only really affects bass, so anything other than a sub box, and you won't notice any difference.
Dynomatting that area however, will make a good diference, making the speakers sound louder and numbing exterior noise a tad.
I also brought that book a while back, not sure where it is now, but tis floating around somewhere!

Another day...another problem...

Thanks for the advice.

I've already brown Breaded that area behind the quarter panel, as well as the quarter panels themselfs. I was thinking of stuffing the padding into the gap between the arch and the outside panel to help reduce outside noise, as well as putting in in the bottom of the hole, (or whatever the proper name for the area behind the quarter panel is), as well as stuffing some padding towards the rear of the car, and up the centre pillar to sort of seal off the area around where the speaker was. If you understand what I mean???

Do you think this would make a difference or do I need to use some other material??? And if so can you recommend anything?

Thanks fot the help.

I guess the padding wold help stop any echo from the pillar, so it'll be one of those jobs that you do without being totally sure of the outcome!

Another day...another problem...

Ok mate cheers for the help.

If anyone else has any views on installing padding in these areas can they please let me know.

Thanks very much.

I was wondering if "the real iceman" could shed any light on the subject.

I would be interested in anyones input. I hope to hear from you soon.

He'll either hate it or love it. If he hates it, expect a new topic to pop up against it, and if he loves it, well, then he loves it!

oooo iv been summoned.

if u want my view its the bit people do the worst. normally people will budget to buy the speakers n once there in u wont b arsed to do anything else.

il say it does make a diffence and is worth sound proofing.

sub enclosures in the boot, i wud proof the boot door, and if u get an umpleasant flapping noise from the numberplate u can use sum sticky pads as this is the worst thing for vibrations and feed back, i also took the heat shield from the bb of 1 car to stop that flapping too much.
the boot floor can be problematic as its large an flat with no vibration stopping corners, cheap solution i used once in the past there was carpet underlay.

if u can afford it after ur speakers go 4 it.

as 4 the baffling it does make deeper bass as the sub will think its moving move air inside the box. another way to get more space in ur sub box is to mount the sub in backwards so the magnet is facing outwards therefore the cage and magnet arent taking up any of the vital box space. this might not be ideal aesthetically as the cones of sum subs are not very sightly but thats what u will hav to weigh up.

correction:: this might not be ideal aesthetically as the CAGES of sum subs are not very sightly but thats what u will hav to weigh up.

So "The Real Iceman", I've already sound proofed the metal panel behind the quarter panel as well as the quarter panel itself using 'BrownBread' but would you say it's worth stuffing padding in behind the quarter panel towards the back of the car, as well as in gap down by the sill, and up into the piller that separates the front door from the rear window. Do you think if I did this it would make my speakers sound any better, or quieten down the outside noise.

I was going to use some Polyfill for the padding, I believe its used for stuffing soft-toys as well as in Dress making or so the Haynes/Max Power I.C.E. Book says.

Hope you can shed some light on the subject.

Thanks again

I have a Cinq and have sound proffed the rear quarters with one layer of conventional sound deadening and a layer of bodyline from www.bodyshopwarehouse.co.uk I also packed the rear quarters with loft insulation, it really does make a difference, more than the sound deadening, you have to be careful with it as the panekls wont go back on again if you put too much in! The hole behind the rear quarter panle reaches all the way back to the sides of the boot and as you cant get sound deadening in there, insulation makes it possible to sound deaden the sides of the boot. 1 Roll from B&Q cost me £3.50 or something and was more than enough to do the sides panelling.

So you just used standard loft insulation? are there differnet types of loft insulation? Does some of it provide more insulation that other stuff?

I might pop into B&Q or homebase or something at the weekend and purchase some of that.

Thanks for the help.

Just standard insulation, make sure you dont get the stuff within a silver wrapping as you cant cut it up and make it easier to get in.
