Note that the M2200 carries an "official" rating at 4 ohms of 300 watts. This means that under FTC regs it was tested at the full 300 watt level into 4 ohms for a continuous period of at least five minutes, a severe lab test that would never be duplicated in home use. There's no problem with the design of the M2200 and if used correctly, again, it can easily power M80s to beyond safe levels.

John, if this was the case then the OP would not be having issues with his amps shutting down after 15 min...

I am not saying that the amps do not put out the power that they are advertised to do so... just that for a longer duration they do not have the cooling capacity to maintain that output... the OP is hitting the performance wall of these amps, which is why i was recommending finding a better cooling option if he wanted to keep his amps instead of buying different amps..

HomeTheaterCooling.com have some really nice cooling fans, I bought two for my Onkyo amp,prepro and they work very good.

I will get out the spl meter and see what level I am damaging my ears. And check out the fans. There definitely isn't much space the way they are stacked now, I don't ever listen at that level for more than a cd but it does sound pretty awesome. I have to check if the fronts are set to large. I was experimenting with the setup, the sub is behind my chair and seemed to blend better if the mains/center were set to large but I am not positive that is what I ended up with.

Dakkon I was looking at your picture, are you into Bujinkan or anything like that?

I think he is into Star Wars. That picture brings to mind of a viral video that was around years ago.

No no, Like BlueJays1 said, that is a img from the Star wars kid video clip from many years ago..

Honestly, i don't even know what Bujinkan is, i had to google it.


Not into Star Wars either, just though it was an interesting video/image..

Yeah, that video was hilarious.

I checked with the SPL meter and Motley Crue Dr. Feelgood was right around 108db when the Yamaha was set at 0db. I think I may have even pushed it up to the +3db that night when everything got too hot, happened once when I listened to Boston 3rd Stage about the same level, got about 4/5 through the CD and one of the amps shut down. I also checked and I have the mains and center set to Large.

I have been having trouble getting into the forum, are they having website troubles of late?

nope. you are having interweb problems man!...


you have to keep in mind how much power it requires to play at a higher volume... every 3db doubles the amount of power...

I was having issues with my old 5 channel amp being driven into the clipping region on a couple channels. My old amp was a Marantz mm9000, rated for 135W at 8 ohms at the time i had 2 m60's and a vp-150.. I don't know what spl i was at, but it was pretty loud when some of the channels were being driven into the clipping region.
