You'll need 4 channelsThat's why I bought the 80prs... I'll go ahead and do an active 2 way and see where that puts me. Once I can use the 80prs in network mode I'll have a lot more I can play with.
As far as getting away from the passive crossovers, how will I power the tweets? Will I need to buy a separate amp or can I use the internal amp on the HU somehow?
I would only assume that if I use the same amp as my mids I wouldn't be able to separate them.
