Default Acousta-stuf question

Hey everyone, I just had a quick question thats been bugging/stopping me from filling my subwoofer box. I ordered a 1lb bag of Acousta-Stuf from PE to fill my ~1ft^3 subwoofer box. When I got it I realized what could be a problem, I have a 500W rms oaudio bash amp which is great except that there is no 'back' on it. So if I did stuff the cabinet it would be touching parts of the amp, and I dont know if that is frowned upon.

If it turns out that they should not touch, maybe insulation would be work better since I could just secure the sheets to the walls?

As a side note, is it ok to use acoustic foam from resonance and some type of filling for damping?

Thankyou

If you are worried about the stuffing touching the amp just use some kind of mesh to hold the stuffing onto the walls of the enclosure.

Yea, I thought about using some of the left over grill cloth for just that purpose. Ill end up doing that if I cant make some enclosure for the amp itself.

I've used polyfill in enclosures with un-backed plate amps before with no issues, all fill materials that I know of are not electrically conductive.

Acoustic foam is pretty useless at bass frequencies unless it's almost filling the internal space, in which case you may as well just use polyester fill (or fluffy fibreglass in sealed enclosures) thay are cheaper and do a better job in this suitation.

Do you think that something like this would work:

It might, but it'd probably be more effective to buy some metal mesh and staple the acousta-stuf to the walls of the enclosure.
