Mounting amplifiers with foam

[pimpnyou204 10+ year member]

Ok possibly completely stupid question but I have no space to put my sub amp. So I have this idea of mounting itto my box but I know the rattling will kill the amp.. So... I thought about using a foam kinda like the cheap memory foam bed stuff at walmart and putting it on top of the box, then using a smaller than the amp size piece of wood (plywood) and using a long screw and use the mounting feet to screw down the amp. Basically the amp would be cushioned from the vibration by the foam... Lol thoughts?

Not a bad Idea, but I think memory foam is too rigid, it is more for impact and slow movement than vibrations, I don't know of something that will isolate better, but someone here might.

Many people mount their amps directly to their boxes and never have an issue. Some people do have problems. If you feel the need, I would just use a piece of rubber under each mounting point, or even some sound deadner would work.

When j had my amp on my box I just used a couple thick rubber washers

rubber is a good solution but what people tend to see is that the amp will wobble more

I have never had a problem mounting my amps to my subbox.

I did once put some deadener on the back of my amp, that was a mistake as the deadener is still stuck to the bottom of the amp.

should have the foil side toward the amp //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

What I have done... Mount your amp to a thin board first. Get a foam noodle "for pools"... With a razor blade cut some half inch or so thick strips the lenght of the board. Put a few strips of those inbetween the mounting board the sub box.

Then screw the amp with mount board down!!!

Works great!

I used the pvc jacket stripped from my power/ground wires as grommets before and never had a problem using them.

rubber washers. Just get the semi think ones as said above u get the real thick ones and ur amp starts to sway LOL. Can get a pack of 8+ at lowes for like $4..

1/4" thick neoprene sheet underneath (sold at craft stores and walmart as "Foamies") then rubber washers for mounting screws so that it is isolated on both sides...no direct vibration. Also don't over tighten the screws as it will compress the rubber washer and take away some effectiveness.

Hmm lots of ideas that are very similar to what I said.. I do have a few pool noodles around lol

My problem with mounting amps to the enclosure was never about the amp vibrating. It was about making a couple really expensive pieces of your stereo a one stop, grab and run for a thief. Never did care for making their life any easier //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

This is very true but my box is pretty much not gonna leave that trunk unless u cut it lol but it does make it readily available.. I had a civic like that and it got stolen lol so regardless of anything it'd be gone lol
