Ok I just got a Pioneer VSX-9300 from my brother for free Anywho here is my issues: 1. There is no sub output so i need a good powerd sub with a high pass filter(kind that has the speakers connected to the sub then the sub to where the speakers connect on the amp. I need suggestions on where and what kind to get or another way aorund this. 2. The Center channel is line out only...so i need a inline amp??? Please ehlp me figure this out...this thing cranks but it's only on 4 speakers..2 front and 2 rear no sub no center...kinda defeats the purpose Thanks all in advance! Dave A.
