looking to have a switch to power on/off sub

thebigbluehouse

I currently have a philips MX5500D receiver system, which has a non-powered sub. I just purchased a pair of Atrium45's (patio area) and a speaker selector, which works great for selecting either the patio speakers and/or inside living area speakers. However, my sub has it's own set of speaker outputs on the receiver, so I would like to just put a on/off switch between the sub and receiver, for when I use the speakers on the patio. Any cheap suggestions.
