I'm trying to change the speaker setup of my 5.1 ht-ss360 HTIB.
Its a 3 ohm system.
What i am planning to do is wire 2 of the 3 ohm HTIB speakers in serial and then wire that duo parallel with one of my own 8 ohm speakers into each front port on the receiver, and use it as a 2.1 system with the sub.
I think the resistance calculated from my wiring scheme is 3.42ish (cant remember but its close)
I just wanted to know if this is a safe way to wire this system.
-- i basically want to have 6 speakers on 2 channels
Connecting your speakers in the series/parallel circuit you described won't hurt anything at all. Sound quality will probably suffer but there's nothing wrong with a little experimentation.
