Hi, I have an onkyo 606, 7.1 av amp and 2 bose passive subs, one has 5 ins and outs, the other has 2 ins and outs, how can I add them to my system, I thank you in advance for any help. Martyn
Why would you ever waste that 606 on bose passive subs?
Get yourself a decent powered sub - even, and I'll say it, a mass market Polk Audio 10", if budget is a concern. Alternatively, if you look in the used market, there's lots to be had for a decent price.
Why don't you just sell those bose subs - 2 for 1.
Martyn, Consider selling the Bose stuff, even just to some guy for parts and use the $$ to fund a new sub. There are a few out there which start well below 500$ and are perfect HT subs while still having some musical talent. The sub you buy could be good thru 1 round of 'upgrade' before you consider better.
