Oh it's plenty cool, Mike!
I can't tell, is the amp getting banged around with the sounds too? If so, I hope the vibrations don't kill the amp!
An enclosure-building buddy of mine uses nothing smaller than 1/4" bolts/glue/strap steel or else sounds will eventually shake the thing apart.
Thanks<p>The amp suprisingly doesn't shake too much, much less than I would expect. Hopefully it will be fine, but I guess I'll find out the only way you can, by trying it.<p>As far as sound goes, it is suprisingly good for a $20 speaker from best buy. I do notice the speaker kind-of loses control of itself alot and thud when it hits, but thats only when it's cranked, and only happens with certain frequencies with music, but hasn't occured with a movie yet. Plus, I can always get a good speaker for it if I feel it's worth it.<p>Do you think I'd be able to run a 4ohm speaker with the amp? That would be giving 2ohm to each chip, but the chips are only running at +/-25VDC and can push 8A continuous, 10A peak. Could be enough to do 2ohm???? I have tried a 2ohm load (1ohm per chip), and they didn't run out of current and make a "popping noise" until it was suprisingly loud.
Depends on the output characteristics of those chips. Some don't mind, others may blow. Always good design to use chips in their operating window! 8 ohm to 4 ohm is a big mismatch, and may not even be noticed at low levels.
Hello,
I happened upon this forum while looking for the thermal properties of different plastics for a medical application. As coincidence would have it, I'm also in the process of building a subwoofer. I don't know if this site would be of any use in the future, but there's a company that makes heatsinks out of thermally conductive ploymers: http://www.coolpolymers.com/
