Cause your not using the correct box... Find someone on here to build you one or at least sell you a cut sheet of a proper one so u can build yourself.. Ported FTW.. bbeljefe can help you with either option I am sure if not mylows and 100's of others... Just post in WTB section cut sheet plans for your type of subs and watch the offers roll in... I see ur across the pond so build sheet is the only way unless you wanna pay 1k for a $200 box. Not hard to build just follow instructions and no exotic tools needed.
I know a little about car sounds, but not box dimensions.
Each sub is in a diff box one ported an one sealed.
I get a lot more sound off the sub in the sealed box, hence my mate saying chuck it in a dual sealed box.
Why do you say a ported box??
Thanks for your help and advice though, an I'll look on the WTB section //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Ported is just louder and zound almost as good as a sealed in most cases. Make a thread in WTB section for box plans needed.. then go toss those pos boxes in ur friendz yard.
