I think we should have a section here for amp gut shots, try and rebuild what ANT ruined when he bought Ampguts, anyone else in?

Sure, why not......ill go first with a really low quality pic of my sub amp, an old school mtx powerhouse the 2300...... http://i1360.photobucket.com/albums/...ps80f94e6b.jpg
Wish I had a better pic, but I don't.........all I know is that bridged into a 6, yes 6 ohm load, it produces enough current to beat the snot out of these....

JL's are notorious for the 3 ohm thing
A year or two ago, I actually considered doing an ampguts section, but my concern at the time was how quickly we would run out of disk space with hundreds of hi-res pics. Now that we're on a VPS it might not be an issue. If we were to pursue it, should we do it here in the forum, or just have a link to a photobucket-style clone?
I vote on the forum......would lead to good discussion and up content! Plus that would keep us informed on new additions without having to leave the forum.
And yup Paul, the 3ohm thing is irritating, but marketing brilliance! Bastards!
they wanted you to use them in groups of 3

Hard to believe that it is rated for 1,200 watts RMS. I was told by a respectable engineer that it should easily do 600 watts RMS though! Unfortunately, it was designed for a max of 13.8 volts and my Mehstang kept tripping the over voltage protection circuit at 14.5 volts. Plus, that micro fan was L O U D!
Here's the internals on my MB Quart Q series.

Wow, that 1500 looks beefy! Nice layout on the 4 channel too. Wish my pics of my mtx were of this quality........maybe ill pull it and one of my matching Rockford 4 channels and get some better ones up!

Not really Ampguts, but a interesting website... in german....
A whole lot of measured amps with their specs...
http://amp-performance.de/106-von-Alpine-bis-Zapco.html
Needs oilin'.
On that Clarion, the fan rotates CCW, yes? So it sucks in ambient air and jams it through the amp?
Are there any amps that suck the hot air out instead?
It can be done either way, I've seen a lot of both... Both have advantages and disadvantages.... depends on how you want to disperse the dirt :D
Clarion has fins right below that fan

In a design where the cooling was basically designed by someone saying "Hey, I think we need to toss a fan up in this bitch." Sucking the hot air out is better because it more evenly pulls the cool air in as opposed to just blowing a patch of cool air on something.
In all the amps I've seen with a fan pushing air into the heatsink, and that fan is integrated from the start (not implemented later on), there's a tunnel with an exit at the opposite side of the fan. The idea being that you create a current of air going through the amp so it cools constantly. IIRC that's what Gordon Taylor (of Genesis, formerly) suggests for his SIII amps (very few of them have a fan integrated, but all have said tunnel). I think he said that forcing the air inside makes for more efficient cooling. OTOH, those SIII's with a fan have it in the middle of the board pulling air out of the case (same as my Twisters). At least I think it's that way; I should have a look at my DMA again to check. :o
Audison LRx does it.

Same for Xtant/MTX amps.
Kelvin
And the crown grounded bridge series... Power base, power tech, micro tech, macro tech, com tech and a couple broadcast RF amps.
In that it is a sandwiched fan, they are in the front, thru a filter and out the sides. DO NOT leave a gap in stacking because the airflow will couple and draw better.
Lunar amps seem to have tackled the problem of heatsink cooling with the most advanced thought involved. If one were to make a class D amp with say, 1500 watts output power, in a Lunar chassis they might have a winner. the DigiPower (?) line with built-in small fans looks like it's not enough cooling to me, in a hot trunk in the summer.
Water can cool up to 10 times better than air, can you circulate water through the frame without worrying about electrical stuff becoming wet ?

it's a "sort of" gimmick, when you consider how heat management in a car is necessary on class AB product, but with the new advanced switching designs, it's probably not as imperative.
The Peavey circuit, IPR, I think is the series, claimed to stay cool even at low impedance and high current through the chassis. If that's what optimized class D is coming to, the Lunar model might not be working as the extrusion costs and added complexity add beans to a bean counter's margins.
Thermal runaway might no longer be a functional deterrent to decreasing the chassis mass, for dissipative purposes.
When they can pull 2000 watts out of a paperback, and you can stuff it under the carpet with no ill effects, things will be peachy..
Newer designs don't get as hot as the older designs did [A,AB,etc..,]
I love that amp.... Never used it, already love it... Connections on one side, Winning.
