Crutchfield is now an autherized dealer. Along with Overtons. I think they might be a little pricy thru them though.
For the best pricing, internet sites such as Wooferset are hard to beat. Be forwarned they don't come with a warrenty even thought they claim.
I went thru my JL dealer in town, who pretty much matched the internet pricing. I have warrentys plus supporting a local business.
