Hi, Im new here but hope someone can help. I have recently bought a Sony STRK670P Receiver, the main reason being that it has an active sub output to drive my passive sub and it seemed good value, it also partners my Sony DVPS525 DVD. My problem is that my AV speakers are a set by Richard Allen, bought back in the days of early Pro Logic when the front L/R speakers were cabled via the passive sub to provide the bass. I want to retain the sub as it is solid and contains 2 x 8 units and sounded pretty good in its day, I not sure how to connect it into my new amp as the sub has both a left and right feeds in / out. My thinking is that I just connect to either one of the inputs from tehsub out on the amp and the internal crossover sorts out the rest, but will this just drive one of the subs speakers? Also my speakers are 8ohms and the amp is 6 ohms, not sure that this is a big issue, but my setup doesnt sound as loud as I think it should when playing a DVD, but is much louder when fed via a phone link from my digibox . Any advice appreciated.
