I'm in the process of hooking up my two Sony Xplod 10" 4ohm 1200 watt subs into my old school Pioneer 760 watt 2 channel amp. The problem is that two of the screws are missing out of the amp. Is it ok if I hook it up like this (below)? I'm not sure if this two channel amp will support the 2 ohm mono operation since the two 4 ohm subs wired in parallel will present a 2 ohm mono load to the amp. Thanks for any help.
