Title: wheel arch sub box advice
Post by: jamie16v on 25 August 2009, 20:09: i am looking to tidy up my install and was wondering what size sub would be best for the wheel arch box i plan to build would be?..
i know a 15 would be rediculous but theyre nice on the lows.. :evil:
im stuck in choice between a 12" and a 10" really.. i have had a twin 10" bandpass for the past 6 months and it kicks nicely but its not very practical when going shopping or putting the pram in the boot :undecided: ....
i already have a couple of 10" subs to play with but i have usually been happy with 12s in the past and my taste of music is changing too.. im not really into the clubby type of music anymore and like more of the indie type of stuff if you get me?.
will a 12 be too big for this type of box or do you think i would be better off sticking with a 10?.

Post by: B-chi on 27 August 2009, 22:05: I'll be honest i've got a new 12" powerplant in a sealed box i'm not using. You can have a listen to it see how it sounds if you want.

See if you like it!

It's in a sealed 1.25cu ft box made from 18mm mdf, screwed & pu glued.

looks nicer anyway..lol any ideas what size box it should have?. i think i have 200 worms to play with..
just gotta get this arch box finished now.. god, it takes some matting and resin dont it?...
Title: Re: wheel arch sub box advice
Post by: jamie16v on 29 August 2009, 18:30: oh yeah, and how many layers of this FG matting should i use? does it have any acoustic properties or is it just the MDF baffle at the front that does all that work?.
i know it shouldnt have any air leaks which i am confident about. ive done loads of this FG stuff before, just not in audio.

Post by: Len on 01 September 2009, 12:38: If its just glassfibre other than the front panel I would use 3 layers.
Plus think about lining it with dynamat.

Where you getting your gear from jamie? I used a couple of those Halfords large repair kits.

Post by: B-chi on 01 September 2009, 19:22: cfsnet.co.uk should see you right.

You can pick which thickness of matting you want. Ideally I would say 600g.

Sound deaden the wheel well, but I wouldn't worry about sound deadening the enclosure. Better off putting an extra layer of fiberglass on it. You don't want any flex at all in the box so if it looks a bit flimsy do another layer.

i used a local motor factors which has proven to be quite wallet damaging. they sell the same kits as halfords. i used two of those kits and bought and extra square of matting metre instead of buying another kit. the box now seems quite rigid, i have also lined it with paper mache (with PVA not wallpaper paste).
all i have to do now is fit the baffle, i got some chip board lying about which i could use or should i spend that extra cash and use MDF?.
also wheres the best place to get box carpet?.. want it to match the boot the best i can..

Post by: Len on 01 September 2009, 21:05: MDF is a bit denser than chipboard. Shame you aint closer as have a few pieces of MDF lying around!

I used PVA/papier mache to get the shape of mine. Ended up ripping all of it off in the end!

How are you fixing the enclosure to the car? I used the 3 self tapping holes.

Post by: jamie16v on 01 September 2009, 21:17: im gonna use velcro or simular.. :laugh:
