Hey guys, I was just looking in this thread: http://www.caraudioaustralia.com/forums/in...=70769&st=0 and absolutely loved the boot install, very stylish yet leaves the boot open to every day use.
My question is, as long as the enclosure volume is tailored to the sub, will a sub enclosure like that moulded into the boot wall, give as good SQ as a custom built sub box in a standard shape, firing through the little door between the back seats?
I've only ever heard one car with one of those fibreglass moulded enclosures and it sounded horrible.
Im interested to hear peoples opinions.

Entering an SQ comp is about spending countless hours working to pay for a great sub, only to be told you need to spend countless hours tuning so you can sound like you don't have a sub at all.

link isnt working for me.
The sub will sound best (assuming equal volumes) in the siffest enclosure, use MDF to re-enforce your enclosure and you will be sweet

The physical position of the sub, and the way it is loaded is important and will make a difference.
Where sounds good in your car though, I have no idea.
Just remember Phase and/or Time Alignment cant help blending the sub bass in with your front stage too.

The biggest issue I’ve come across with fiber glass enclosures is getting the wall rigid enough to avoid vibration or resonances.
I believe that fiber glass is best used as a finish and not for construction. The idea of using a combination of MDF and fiber glass for the enclosure is a good one. But, the MDF panel may resonate at undesirable frequencies.
Over the years I have tried and heard many systems with fiberglass enclosures and while some sounded great, many more didn’t. In all cases I was left with the curious notion of how much better they would have sounded with MDF enclosures.
IMO Wood works and fiberglass might.
Cheers

to be honest, thats the makers lack of skill with fibreglass. if we can make boats and rigs out of glass to withstand tens of tons of pressure. im sure a tiny little subbie will be fine to. a glass box shouldn't flex if made right, sam as mdf.
dont get me wrong tho, i prefer my wooden boat over dads glass boat

Try that, it works for me. In any event, it's the Magna boot install in the first page of 'rides/installs' forum.

IMO - Fiberglass works as well as MDF... BUT only if it is done correctly. 3 layers of FG is not enough. make sure you use plenty of matting. Any one can FG but not too many can go it properly. The matting is what gives it strength the resin just holds the matting in place. once youve finished your shap and doing your layers get a grinder and grind off any dags then do another 2 layers and grind them back then do a nice coat of bog ON THE INSIDE. a smooth box will sound better - especially if its ported.
Use MDF as much as possible and only use glass where you have to. remember to SD where the glass touches body panels and to secure it to the car correctly

Deaden the enclosure.

Andy Jones, IASCA Street X SQL is code for "I half ass everything." Basically you are saying you are not loud enough to do SPL, and have no idea what it takes to do Sound Quality. So you meet in the middle with a quiet system that sounds like ass. Good job at being mediocre.
