My builder installed dead single gang plates for my 5.1 system and I need to find a single gang plate that I can pass the speaker wire through and mount my satellite speakers on (Infinity TSS-450). Any info or other suggestions would be greatly appreciated. Thanks!

google "Electric box cover speaker bracket"

scroll down $4.95 each.

BIG mouthinDC, you never cease to amaze me, you find the coolest stuff.. I needed that last year. Now I'm going to get those to replace what's up there for my rear speakers. GREAT FIND!!

Actually I got to thinking if nothing like it existed it was another product opportunity, but it took me about 60 seconds to find that one.

Problem is you are at the mercy of your contractor to put the electrical boxes in the right location. Also there is an obvious weight restriction.

OR, the OP could just take some blank metal covers and attach the brackets that came with his speakers.

Probably save some $
