I just purchase an amp that I'm taking delivery of this friday and it's coming with a great condition 4 space A&S Airack that's their standard 20" deep. I already know that I won't be using it so I'm gonna offer it up to another member. I just got a price quite from them today and a new one cost $566.00 plus shipping estimated at over $60. Offering mine for $350.00 shipped and PayPal preferred. Here's the companies link: http://www.ascase.com/productcart/pc/viewPrd.asp?idproduct=351&idcategory=61 I'll post pics once it's in. PM me with interest. Thx.
