mono block or 2 channel??

[n2audio 5,000+ posts]

my tru H1. tested efficiency with dmm and clamp.

What was the % eff.?

At what impedence?

At what % of rated power?

in that case, refering back strictly to the original question at hand... can you show me two amplifiers from the same manufacturer and era, both the same type internals, one a mono block one a multi channel amp, and prove to me that by simply adding a channel you increase efficiency?
ive already stated that yes, you can make generalities of that nature, but it still is a generality and is not pertinent information to the question asked IMO. and prowler, if you can find a case like i have posted above, then and only then can you say that i refuse to admit my fault in the presence of a fact. because so far, you have been speaking in generalities and not fact //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

What the hell are you talking about? Im not talking about adding/taking away channels, im talking about class D and Class A/B architecture. They are DIFFERENT. Class D is more EFFICIENT given the same manufacture, similar parts, built in the same era. If this was not true, then why would manufactures BUILD Class D amps in the first place? Surely its not just because of the lower loads, many old school A/B amps could drop to 1/2 ohm per channel or more no problem. Could they do it efficiently? No, so give me a good reason...
So again, I DARE YOU, find two amps, I dont care how many channels, as long as they are Class A/B and D with all the conditions stated. They can have similar power levels to make it easier on you, and PROVE that the A/B is more efficient.

BTW, have you realized that your the only one arguing your point? Have you realized that my first post was not attacking, yet you bit back with criticizing retorts. Maybe you need counseling, I'm sure caraudio.com can aid in the fund...

You see I can be mean too //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

OK I'm sorry to start all this trouble. I will clear up the thred question. I was looking for amp to power my new Sound Splinter Sub and i noticed you could produce more power on a 2 channel amp bridged even at 4 ohms for less money, than you could on a mono a 2 ohms so i was wondering if there was a downfall to buying the 2 channel in this case? sorry about the trouble.

for my 2 4ohm subs, a 1ohm stable class D would have been a better choice...but instead i got a A/B, bridged it, and am only getting 350watts...if i would have spent another $100, could have gotten a beautiful mono amp, hooked up my subs at 1ohm, and enjoyed using my subs to their full potential...i wish i would have realized i could hook them up at 1ohm before i bought my amp! i was too new to this shit to realize!

**** me! they still sound good though, i just want to know what they are capable of--oh well, maybe next year!

can i hookup just my 2 front speakers to this amp?? they would each have 125 watts(rms) to them...each speaker is 50watts(rms)... or should i just sell this queer *** amp?

What's the voice coil configuration on the SS sub? Is it a Dual 2 ohm or a single 4 ohm? If its a dual 2 ohm, you can parallel the coils to get a 1 ohm load and get lots of power from many class D mono amps. There is nothing wrong with using a 2 channel amp and bridging it to run a sub. If you are looking at more than 500w, however, you may benefit from the increased efficiency of a class D amp. Class D amps are pretty cheap these days, so I don't think its going to necessarily cost you much more to get one over a 2 channel amp.

For the record, I highly doubt that there are many class A/B amps with higher efficiencies than a class D amp. Some might get close to a class D amp's efficiency, but typically only at full power. With music, at less than full power, a class A/B amp's efficiency will drop to about half of full power, while class D amps will almost maintain their efficiency at lower power levels. A typical class A/B amp may be about between 25 - 40 percent efficient with music, while a class D will be between 60 - 90 percent efficient, depending on load. If you were in a spl competition, the advantages may be a little less dramatic. For a daily system, on a higher powered systems on stock electrical systems, the difference can be dramatic between the two amp topologies.

^^^Thats a good point. My A/B amp at 500rms was dimming my lights about as much as my 1500rms ampman audio with music, forgot to point that out...

LOL.
OK, Ok, they need a smiley where one smiley is taking another smiley, has them bent over and is reaming them from behind while holding up the devil horns sign and sticking is tongue out. //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif
