I am using an old Aiwa DPL receiver to power my SVS based DIY sub. Currently I have the sub out from my AVR225 running to the inputs on the back of the Aiwa using a Y splitter. And then from one of the channels I have a wire running to the input termninal on the sub. My question: Am I able to utilize both left and right outputs from the Aiwa? My initial thought is that this would more than likely be bad somehow....but I can't resist the urge to pump twice the power into the sub. It probably won't work, but I had to ask.. Thanks.
