If its the pro edge tower, then yes, there are adapters that fit the wet sounds speakers and for the upper and lower speaker spots.

Honestly, id remove the 6.5" coaxials and mount the Rev-8 in their spots and just rock them. They are larger and they are HLCD. On both accounts, they are going to dominate the smaller coaxial 6.5". Further, you can re-wire the at the amp, anf gain more power to the rev-8, v's mounting them to the lower spots.
