I have found out that the Ampeg B2R Ampe probably is not made for two 15 inch cabs. So I have decided to take one of them back for a refund. About $100 bucks and put that towards a 4x10 cab. Maybe an Acoustic brand. WHo knows. There is a Pawn shop near by that has a old Crate 410 for 129...might look into that.
