Does it make a different what class the amps are?

Class D's are the most efficient.

^ some class D's are also more efficient then others...

there are also a few other classes that have higher efficiency then plain ol A/B, but it is unlikley that you will ever hear a difference...

What are some good names to look for?

I went to my local audio spot and hifonics amps where selling like hot bread. Good deals I guess.

hifonics are ok ive never had anyprobs with them they push power for a good price i guess u cant beat the combo

can you please explain what you mean, more efficient how? Does the amp produce power more accurately than A/B amps?

Yes, more efficient. Less wasted power. Take less current to make power.

Accuracy has nothing to do with efficiency.

So a A/B would draw more power from your battery and more strain on your alternator than a D? Are D amps only made to produce low frequency?

fusion has very efficient amps.

so does jbl. streetcustomscc has the 6000.1 i think and he said it puts out 8,500 something watts @4ohms on a 14.6 v electrical system.

Somebody runs hifonics. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Yes most of the time a class a/b will draw more current than a class d for the same power.

There are full range class d's and tri-path which is similar in efficiency to a class d plus im sure a few others that I cant come up with at the moment.

hmm, i was so sure i read somewhere calss D draw the most current. i guess im wrong.

They most likely draw the most overall current since there are few if any 4000 watt class a/b amps.

But watt for watt a class d will usually draw less current than an a/b.

Question what type of amplifier would be most efficient in powering two 4-ohm dual voice coil subs, mono or four channel?
