Mounting a small amplifier under cabinet?

Question

Bought&nbsp;Fosi BT20A&nbsp;, like it so far.&nbsp; To my ear it beats an average home theater receiver, being also very small. The only good place is under cabinet.&nbsp; I am out of ideas how to mount it.&nbsp; I could buy a plastic clamshell similar to one holding my RV radio under the cabinet but this shell is huge, Fosi is tiny, 4" x 1.6" front, 6" deep front to back, weighs 1 lb.&nbsp; It's all metal, no vent holes, does get warm, not hot.Are there any thick double-side adhesive strips to leave a spacing 1/4" or so from the cabinet and hold it without shaking?&nbsp; Eventually I could make an ugly plywood tray and paint it black but maybe there is an easier way?

Yes, high quality industrial double-sided table like 3M VHB is available thick, like 1/4" or so. That will do what you want and last forever doing it. Another option is high-quality industrial Velcro which may even be better in this case.&nbsp; Go to Grainger or Fastenal, not Hobby Lobby or Wal-Mart, and tell them what you want. It's available and will do what you need for this.&nbsp;

Which one you think would hold it more steady, 1/4" double sided tape or same thickness Velcro?&nbsp; I'm not worried about it falling down soon - maybe with time, when the glue deteriorates.&nbsp; But I'm touching the amplifier often, adjusting the volume or flipping the switch on/off, it has no remote.&nbsp; Volume and other controls are small, I don't want it to move/shake under my fingers.

I have been looking at thoes also..&nbsp; although for home use as a internet radio/bluetooth etc..&nbsp;&nbsp;the only thing I worry about using tape is the heat that builds up in RV's when we are not using them, heat and extreem cold would be the undooing of most tapes I have tried so I wouldnt totaly trust tape myself.&nbsp;&nbsp;is it easy to open up the case for that? if it is, and you have the space insice I would drill 1 or two holes in the case that you can put a bolt or two through and bolt it to a surface.&nbsp; that would be the cleanest install the second option I would look at is building a housing that it is captured in out of wood that ataches to the surface after you slide it in place..&nbsp; &nbsp;the third would be bent acrylic you can use to squeeze it against a surfica as you mentioned in your original post.&nbsp;&nbsp;

I've been playing all these scenarios in my head, believe it or not.&nbsp; Other than 2 bolts from inside the casing all seem to be a pain, with my modest fabricating skills.&nbsp; Will see if I can open the case.&nbsp; Yes, extreme heat in a closed RV is what I've been worried about, with tapes.&nbsp; Foam and semi-cured things like that adhesive don't like heat.&nbsp; "Out of wood"... like I wrote, I could make some ugly tray 🙂 ...One option seems doable to me is to attach it similarly to my solar panels only upside down. 2 angles back to back make a Z-bracket, bottom of Z support the device, one on the left and one on the right - here I could use a sticky tape.&nbsp; Top of each Z is screwed to the cab like that clamshell that holds my radio now.&nbsp; For solar I used slotted angle profiles, for this device I have 1x1 fiberglass profiles, epoxy would hold&nbsp; the profiles together, but they are red 🙂
