On a budget, surround system --- INPUT REQUESTED

Hi, I have a JVC RX-6030v receiver and want to know if this speaker combo is ok for surround sound. Bose 301 front, Cerwin Vega V-5C center, Cerwin Vega AVS-Sub8 subwoofer, Cerwin Vega LS-5 rear. I already have the receiver and Bose 301's. The rest I found a deal on... Yes will demo before purchase.
