Subwoofer RCA Wall Plate

[Blu-Benny]

question for you guys.

i've never had an HT w/a sub. i'm running all of my cables in-wall right now.

the only wall plate i can find is a single RCA connection. like this:



do they make a 2 RCA wall plate?? i can't seem to find one.

should i just use a 2 to 1 adaptor from the sub to the connection?? is there any drawback to that??

assuming of course that the sub has a left and right rca hook up on it.
