Multi-channel w/large sub output

[bikejunkie223 10+ year member]

Excelerater, you don't get it. The Memphis Belle *IS* a 3-channel amp, as well as a 5-channel. You BRIDGE each pair of the front four channels -- as I stated before -- and it runs 2 x 225 watts RMS at 4ohms, and you then run the sub channel at whatever you want (600 @ 2 ohms or 1100 @ 1 ohm).... THREE-WAY MODE (NO REAR FILL).

do you need 225w x 2 for front components? Mine are way clean and rock at 75, 225 is gonna melt stuff unless you run some seriously expensive hardware up front. If it's just power you want try:http://www.crutchfield.com/S-uJ7Hm3nES5I/cgi-bin/ProdView.asp?wm=fp&I=049RAA2400&g=100 Big fat clean power, low buck cost of entry. I just think this is too much amp for components. Read the review for this bad boy @:http://www.pasmag.com/gear/testreport_article.asp?ID=161 They seemed to think it owned, and at half price at crutchfield, you've got nothing to lose. see the specs @:http://www.crutchfield.com/S-uJ7Hm3nES5I/cgi-bin/ProdView.asp?g=120&id=features_and_specs&i=049RAA2400#Tab

2 x 225 too much? Come on... when are your components going to truly see that kind of power? (That's just a rating saying the channels are capable of that kind of unclipped output). The idea behind more power is really about providing your system more dynamic headroom. I bet you could tolerate a clipped signal coming from your 75 watt amp, which is a far worse condition as far as your crossovers/speakers are concerned than is too much power.

It is the same old story: More power and the amp's gains are simply run lower translating to less noise and distortion at the maximum clear volume that is tolerable. Melt? Again, if you run massive amounts of current at them over extended periods of time, but that just ain't gonna happen - a person's ears would bleed first.

Just for the record, the 225 watts RMS will be mated with a Z-series CDT crossover and 6.5" 2-way Eurosports, rated to handle 180 watts RMS.

That rating for that amp is 225watts RMS, not peak, so yeah, despite having a gob of headroom I think most speakers will have problems with that much continuous power. Please don't talk to me like I am a nOOb that does not get the difference between rms power and peak. I also understand the concept of dynamic headroom. I also know that the average set on component speakers are rated to handle 100-125watts rms. So, it is my opinion that regardless of where the gain is set, exceeding the speakers rated continuous load rating by 100% (200w rms) is not a good idea if you expect those speakers to live long. In order to get speakers that can take that kind of wattage, you have to spend well over $250 a set. That moves into the "serious hardware" category in my economic world. For your information, I would not be able to tolerate a clipped signal and distorting speakers, which is why I have an amp in the first place tough guy.

Tough guy? What is that? Okay, first off... did you not see the speakers and crossovers mentioned? (I noted them in the last line of my post). Their value exceeds your price point by double or more, if that really matters. Second, how many times do any set of speakers truly see even 50 watts RMS over even a 2-3 second period? The size of the amp doesn't mean speakers automatically get "X" amount of watts. Sure, most speakers *would* have trouble receiving 225 watts continuous - few component speakers EVER see that kind of power - I DON'T CARE HOW LARGE THE AMP. Extra power simply allows for more driver control during peak demand translating into cleaner/clearer sound. The better the speakers, the more prepared they are to not only take the power, but benefit from it.

I agree. I just think given the equipment stated 200w rms would nuke them. It would not nuke yours, yours are very nice, I just didn't like being treated like an idiot, and took you for a typical e-thug. Clearly this is not the case, and I apologize for the tough guy blast. I personally would not use an amp on components that doubled the rating, but that's just me.

"Given the equipment stated?" What "equipment stated?" (I started the thread). Not sure where you are getting 100 watts/channel.... And, who treated you like an idiot? Where? As for excelerator, twice I pointed out the amp could be run in three-way mode and twice he missed the point. Cheers....

Wow, I'm a dumbass. I totally got confused which thread I was in! Sorry about that. Actually, you did when you implied that I obviously cant recognize a clipped signal from an overdriven amp. So, anyway peace-out.
