im thinking of selling my class D for a 2 channel a/b with the same power for sq reasons

are class D amps really that bad at sq?

i know they are great on your electrical sytem

but i can swap my dei for an almost new 18w3 and get a hifonics on it, im thinking the sq will rock

 

i dont see the need for a class a/b on a sub. if you want better sound i'd say start by concentrating on yout car before you work on the equipment thats going in it.

but, as far as i can see alot of them push the 500rms i would need for the sub, don't they make a/b amps for subs? i used to use them

There has been debates on whether the classes between the amplifiers makes a difference or not.

With subs, you're not going to hear a difference between classes. If you do hear some difference, it's not because of the class differences. It's probably the built in processor, or maybe your mind tricking you...


Does a class C vehicle gets you to point A and B better than a class A vehicle? (and no, i'm not talking about comfort or the options on the cars. lol)

 

ok

so basically it doesnt matter but i might as well stay with the class D as its easier on my electrical system?

 

1100w of class A/B at high volume will draw marginally more current than 1100w of class D.

I would stick with the class D since you already have it.

Now if you listen to your music at low or moderate volume level, then flip a coin.

huh? what was that?

 

I am one of those that would disagree Class A all the way.
My 1000W class A sub amplifier used 80 amps LOL

I would focus on your speakers first, they are your weakest link!

plaease, elaborate


how do my speakers have ANY thing to do with which amp i use for bass?

 

if you want the best sq, you could find yourself a tube amplifier. then again, those are rediculously expensive and hard to find.

thanks for the help

 

Class D amps typically output a higher level of noise than A/B amps, but this noise occurs at much higher frequencies than your sub is crossed over at, so it is filtered out.

I have never personally heard a tube amplified system, but I do know that the "special sound" of a tube amplifier comes from the noise inherent to tubes. To me adding noise to a system does not add sound quality. From what I hear tube amps are an aquired taste.

remember that for the most part sound qualty is subjective. I heard a tube amp system recently and i kinda liked the sound. I know the idea of adding noise to a system and saying it sounds better seems strange but you'd have to actally hear one. They have a very warm and open sound. I'm still thinking about tube amps to drive the upper range of my logans (280hz and above) and then using the solid state to drive the subs.

To each his own Tubes do have more noise when pushed to the limit.

Your speakers will put out far more distortion than "almost" any amp ever will.

Class D amplifiers have the worst ditortion ratios. You will only find Sub amplifiers using Class D technology. The reason is the relatively slow frequencies and the fact that actually hearing the distortion is harder with low frequencies vs highs.

For a normal stereo I would say Class D on the sub is just fine. For High end I would use a class A.

Invest in your speakers first your amplifiers second. I don't care how much you spend on an amplifier you can not make a crappy speaker sound good.

 

ok thanks but a few things

we are talking about bass here

are you telling me certain subwoofers come with 'distortion'?


as far as i know a subwoofer will only 'distort' if installed incorrectly

correct me if im wrong but which sub would i buy that would distort no matter what install its in?

i would be using comp vrs as ive grown a custom to their sq, the square kickers lack badly

now is it possible that a class D amp will bring distortion into the picture? only way i could see them distorting is if they are underpowed

like when i put my 160.4 punch amp that pushes 20 x 4 rms to the cvrs i had, they distorted at high volumes of course

so im lost

i disagree a crappy amp will never get good speakers sound good, ever heard some nippon americ speakers on a hifonics amp? i have ever heard some mb quarts on a pyramid amp? i have

just a friendly debate guys, don't take anything personal ive seen a few '**** off's in the audio section recently

 

Every component in your system will add a certain level of distortion to the sound that you eventually hear. When you say "distort', I think you mean audible distortion. You won't really hear distortion until it is over 10% and thats pretty high. This generally will come from an incorrect installation like you were saying or bad tuning (ie gain too high, settings on deck messed up real bad).

i get that

 

A watt is a watt. If the pyramid amplifier was not over driven it would sound the same as a high end amplifier of equal wattage. This does not mean Pyramid doesn't overrate the hell out of there amps. But as long as the pyramid was not over driven and the high end amplifier was putting out the same "measured" wattage about 95% of the population would not "hear" the difference.

No speaker reproduces sound with 100% accuracy. The speakers are the weakest link in the system. You will easily tell the difference from a quality set of speakers vs el cheapo, even at low power levels.

Try doing a blind test sometime I think you will be surprised.

Your class D will work fine in your situation. Yes your class D amplifier will introduce distortion even when not over driven. This is what the distortion ratio numbers mean. It is a percentage of the signal that the amplifier "distorts" Class D has the worst numbers.

no it wouldnt, i have done a million and one tests on good and bad amplifiers and even with the rms exactly te same the better amp always sounds better, especially for mids and highs

you said they're the same RMS value but where did you get that number? chances are if you benched both amps you'd get very different numbers.
