I'm looking for some Diamond Audio M651 or s500's at a good price (or for trade for a Rio Reciever and a custom empeg dock). I know the chance is slim, but i thought i'd post and see if anyone has any hook ups or might just happen to have some used ones laying around. I really only need the mid to use for rear fill to match my s600s up front. It's really hard to find these things for a reasonable price... all the local dealers have insane markup. Thanks!
