Okay, so I'm thinking of

JBL woofs and tweets 60w

Sound Ordnance amp 75w x4

rockville sub either 8in 150w or 10in 200w, there's only like 15$ difference, but I need to measure

OR

skar 80w component with skar 100w x4 amp ? Skar seems low end, but if it works it works?

Or do you think it'd be better to mix the 60w speakers with the 100w x 4 amp?
