Ok, question....

I have a Eclipse EA4000 (2x30amp fuses)
http://www.eclipse-web.com/amp/ea4000.html
this is pushing 75w rms 4 ohm x 4 ch going to front and rear
Polk MMC-6500 125w rms speakers front
Polk MMC-650 60w rms speakers rear...

also have a Eclipse EA2000 (1x30amp fuse)
http://www.eclipse-web.com/amp/ea2000.html
this amp is 60w rms 4 ohm x 2 ch
this is pushing 175w rms 4 ohm bridged to my sub ED 11Kv.2 Dual 2 ohm

just got a Eclipse XA5000 (3x25amp fuses)
http://www.eclipse-web.com/amp/xa5000.html
50watts RMS x 4ch + 300watts x 1ch @ 4ohm
75watts RMS x 4ch + 450watts x 1ch @ 2ohm
150watts RMS x 2ch + 300watts x 1ch @4ohm BRIDGED


XA5000 is going to push the Polk MMC-6500 125w rms front speakers bridged and set gain by DDM to 125w rms x 2ch
going to push the ED 11Kv.2 Dual 2 ohm with the sub ch at 300w x 1ch 4ohm


the question is the Polk MMC-650 60w rms rear speakers
should I put them on the
1) EA2000 which is a perfect match 60w x2ch on 60w speakers (maxing out the amps useable power level)

2) put them on 75w x 2ch of the EA4000 and set gain to 60w x 2ch with DDM, not use the last 2ch on the 4ch amp

3) bridge the EA4000 to 150w x 2ch and set gain to 60w x 2ch with DDM.....

what I'm after is keeping amp as cool as I can and lowest possible current draw... I'm going to be maxing my 4ga power feed with the XA5000 and one of these amp with it and I don't want to have to run another bigger wire....

what do ya think.....

 

no input anyone???

basically wondering if its better to push an amp at 40% of peak capacity and will the sound quality be super clean and drive to speaker to the fullest potential or match my 60w ch to 60w speakers....

 

I dont think you'd tell a difference between any of them, I would stick the 60x2 amp on them and call it good; it's a perfect match pretty much, cant beat that.

 

Thanks Bartak, thats what I was thinking, just wanted another 2 cents..

also the EA4000 will sell better that EA2000 will ....

Would you set the XA5000 that I'm going to bridge to 125W to match the MMC6500 125W RMS, or do you think these will take the 150W ch x 2 it going to put out bridged...

thank they will handle an extra 25W....

 

I don't know sh*t about this stuff, but from what I see and hear. I think you would be better off running amp at less than full throttle. Notice how your system gets more distortion at higher volume levels, (upper end of amp output) but back it down to maybe 2/3 or 3/4 and the sound is deffinatly better. I think the amp would work less and run cooler also. I believe amps are opposite from speakers, in they would work better at a lesser percentage of their rated output, where good speaker need something to drive them in the upper parts of their range to get the most out of them.

Again just some observations of mine, there are far more knowledgable people here than myself.

 

I see your point, but also the EA2000 at 60W ch x 2 is the useable power level, max is 100w ch x 2
it outputs 60w at 0.05% THD, 100W at 10.0% THD... last 35W to 40W is unuseable

 

I would THINK they would be able to handle it, but if you want to be on the safe side I would just set them at 125 watts...

 

True to SOME extent, I really dont think he is going to be able to tell a difference. A good stereo should not distort the more you turn it up either, at least until you get a ways past the volume you set your gains at, then stuff could get ugly. If it were shattier quality amps (yes I just said that) I might suggest the other option due to some of those reasons (higher THD, higher heat, etc), but this amp should have absolutley no problem, after all, it is designed to run that way...

 

Thanks for 2 cents Guys...
