oldsoundguy Posted June 1, 2014 Report Share Posted June 1, 2014 For example you have a 2 ohm stable 4 channel amp that puts out 170w at 2 ohms and 120w at 4 ohms. Would the amp be more efficient at 2 ohms or at 4 ohms. I understand that the more power the amp has to put out means more heat so it puts more strain on the amp so does that mean less sound quality power to the speakers? Then if you have a 4 ohm load on the same amp, it makes less power which means less heat and strain on the amp will it be more efficient and sound better? I tried to google these questions and really couldn't find much on the subject. Just wanting more knowledge on the subject is all. If this happens to be a stupid question don't be afraid to say so. lol 80prs Arc Audio Xdi 1200.6 (using active crossovers) Freaking awesome amplifier Incriminator IA 10.1 Focal PS 130v 5.25 (doors) 4" Faital pro Neo (kick panels) 3" Faital pro Neo and focal tweets( dash) DC Audio level 3 12" custom box designed by joex built by me AGM front, XS 750SE batteries rear DC 180 alt 99 Toyota Tacoma extra cab http://www.stevemeadedesigns.com/board/topic/179476-my-small-build-turned-into-the-ongoing-build/ Link to comment Share on other sites More sharing options...
Phaeton Posted June 1, 2014 Report Share Posted June 1, 2014 I would think that it would be more efficient at a lower ohm, When you [i at least] use a amp at a lower ohm, it gets hotter, some of that energy gets converted to heat rather than going to your speakers. lower ohms mean less watts being put out but less strain on your amplifier, therefore less heat. 1997 subaru legacy outback Four 15's in a almost wall Rockford Fosgate t2500-1bdcp Rockford Fosgate T400-4 on tweets Rockford Fosgate T400-4 on highs Rockford Fosgate T400-2 on midrange Rockford Fosgate T400-2 on midbass Optima Yellow top batteries 270A Singer alt (working on a bracket for a second) Lots of Second Skin Link to comment Share on other sites More sharing options...
Krakin Posted June 1, 2014 Report Share Posted June 1, 2014 More efficient at 4 Ohms. Also by wiring up you get more control over the driver, as in dampening factor.

oldsoundguy Posted June 1, 2014 Author Report Share Posted June 1, 2014 I just googled damping factor and had some good reading. I will have to read through it a few more times but its very interesting. 80prs Arc Audio Xdi 1200.6 (using active crossovers) Freaking awesome amplifier Incriminator IA 10.1 Focal PS 130v 5.25 (doors) 4" Faital pro Neo (kick panels) 3" Faital pro Neo and focal tweets( dash) DC Audio level 3 12" custom box designed by joex built by me AGM front, XS 750SE batteries rear DC 180 alt 99 Toyota Tacoma extra cab http://www.stevemeadedesigns.com/board/topic/179476-my-small-build-turned-into-the-ongoing-build/ Link to comment Share on other sites More sharing options...
Krakin Posted June 1, 2014 Report Share Posted June 1, 2014 But just so you know, I kinda wen ADD and got to dampening factor. Efficiency is just merely the percentage of input amperage to output amperage.
