Hey All,

I have a AMC+ 120 mixer amplifier and Bose Freespace 3 series II speakers for free through a job of mine and they are setup and working great. I found some older sony S.A.W subwoofers and was wondering if I could set these up alongside my existing speakers. I don't know exactly how to wire this though. Here is amp manual - http://www.australianmonitor.com.au/assets/Uploads/Products/Australian-Monitor/Mixer-Amplifiers/Constant-Voltage/AMC-Plus-30-60-120-250-manual.pdf
Here are photos of amp and subwoofers.

can I wire the subs using the 4ohm outputs? would i have to link them in parallel or not?
 
Solution
Amps instructions state you should not use both the low impedance 4 ohm output at the same time as the 70 or 100v outputs (top of page 6)
Sony SAW subs seem to have been self powered but your pic isn't.No reason to shield a subwoofer either. If they are self powered you can connect them to the XLR line output of the mixer amp.
If they aren't self powered then you can't use them since they will not have 70 or 100v step down transformers that the Bose must have in them. If they didn't they would have blown when you connected them to 70 or 100v dc output
By the way that amp isn't stereo. The inputs are but the output is mono.
