Sounds like the Double Up might be the ticket for you. As you sound like you want tunes for the rider but also a jamming party cove/sand bar system.
If you go with the 80's, the SYN-2 is the amp to power them. It will also have enough power for a second set if you want to add on. If you go for the Double Up. You can do a couple options. Best option in terms of power and performance but also the most expensive is the SYN-6. It will do 200x2 and 155x2 in 4 ch mode. You could step down to the SYN-4 which will do 125x4. You can run the SYN-2 on the Double Up for 350x2 so 175 to each speaker. It will get you more power than using the SYN-4 but I prefer to run the SYN-4 or SYN-6 on the Double UP. So you can cross over the MB-8's lower than the 60's. Since you have a 8 inch driver paired with a 6.5 inch driver. I like to cross them over different to gain more balance.
Hit me up and we will get you taken care of. Thx
