TaylorFade Posted September 22, 2015 Report Share Posted September 22, 2015 Cool test. I tested that amp January 2014. My one little thing I will nitpick is you need to test multi channel amps with *all channels driven*. My loads are odd numbers, but just for an example, I got 150w @ 5 ohms with one channel driven but that number dropped to 115wpc with all channels driven. But thanks for the vid. Keep up the good work. Link to comment Share on other sites More sharing options... 671 764 1

Keep up the good work. See, I questioned the same thing when BigDWiz put a JL audio 3 channel amp on the amp dyno. It did amazing results, but he tested the 2 channels bridged, then he tested the 1 mono channel. Way under rated, but now is that due to the amps power supply that is meant to power all 3 channels but only powering one channel so it has extra power to throw at that single channel for a higher result. Same thing with the 4 channel, if anything you need to bridge the 4 channels down to 2 channels and then run the amp dyno in stereo mode at needed impedance. Im sure that if your testing all 4 channels or the 2 channels bridged the amp will yield different results than just testing 1 of the channels being dynoed since the power supply is having to drive all 4 channels and not just 1. Here is the thread where I questioned just what you confirmed Fade. http://www.stevemeadedesigns.com/board/topic/199311-jl-audio-xd5003-amp-dyno-test/ Link to comment Share on other sites More sharing options... 4.2k 14.5k 99
