Hello - I'm new here, wondered if anyone could help. I've just got a (very cheap) JVC SP-THA85 speaker system as the dvd part of the system was knakered. I am trying to hook up to my AV amp (PIONEER VSX-516) - the surround speakers are no problem, but the sub is designed as part of the "integrated package" and so contains an amp for all the other speakers. So I was just wondering if anyone knows if I can use the "system" type active sub as a standard sub with conventional amp. That was a long old explanation! Would be grateful if anyone has any ideas!!
