amp mounting upside down

Hi,

I’m planning on a ceiling mount for the amp, where the amp would be upside down and there is nothing in amp manual that specifically either allows or prohibits that orientation. The amp would be screwed onto a metal plate about 50mm wide and 250mm long which in turn would be screwed to joists in the ceiling. Would that create a problem with ventilation, if so would it need to be spaced off the ceiling to allow airflow, or would I have to construct a U shaped bracket to mount the right way up and how much gap between the top of the amp and the ceiling - looking at pictures of the rack mount I would imagine ½ inch would be more than adequate

Yeah, because discussing the search function with Gainsight has been so productive in the past. 😅

Thanks guys for all the suggestions, however I have chatted with a technician and his ad vice is that as the manual does not give upside mounting as an option then they would not recommend it, So a more complex bracket now needed.

The Sanus website states their mount is Designed for flexible placement – mount Amp vertically or upside-down

I'd trust Sanus' public statement on a website before I'd trust a support person on the phone. Sanus knows more about their products than someone reading a script.

Also Sonos resells that mount, if they disagree with the inverted option it is unlikely they would recommend and sell it.

Thanks for this, but on the Sonos page it is only classed as a wall mount.
I have had a further reply on the chat:
There is no internal documentation that advices otherwise so it would be a matter of testing, just make sure the Amp has proper ventilation. If you encounter issues with volume clamping down to 15 or the Amp flashing red or it stops producing audio and it not because of ventilation, it may be that the orientation is causing the issues. Also, it is recommended in case that the Amp needs to be factory reset that it's somewhat accessible as the reset process requires a button press

I’m disappointed that Sonos cannot give a better response and on balance I do not want to take the risk so a more ugly U shaped cradle bracket to mount the right way up under the ceiling is what I am going for

I’ve been trying to visualize your mounting of the Amp upside down on a joist that typically runs perpendicular to a floor or ceiling between floors. Can you post a drawing? It doesn’t have to be professional just a crude rendering will suffice.

Even if the mounting plate is positioned between two joists why would the amp need to be upside down?

This is a picture of the install site, it would go just to the right of the cctv into a wooden ce
