Im after a stealth box for my B5 A4 but i dont like the Auto Acoustics box as they are very flimsy fiber glass backs to them and the sound isnt much cop from them. I want to put either my old Kicker Comp 12" in it or get my mates Eclipse Titamium 12". They both need around a 1ft cubed box. Is there any other alternative than the Auto Acoustics box? Or can these type of boxes be home made is there any guides on makeing one?
