Thanks
@March Audio and
@Soniclife that's a very good option and really appreciate the help. Out of interest, Alan, how long is shipping to the UK taking at the moment?
I actually think I could mount them behind the TV unit in each corner by each speaker. I wonder if I could buy or fabricate a bracket to securely hold each amp in place. Or possibly get just the P452 and mount it on the back of the TV unit. I'm going to have a play around with a few options tonight and see if I can find a good placement for either the P452 or P451's.
I've just spotted my Bluesound Node 2 has a 12v trigger so that could be an option, I just need to check at what point it would trigger.
