WillistonAudioLabs Posted October 8, 2012 Report Share Posted October 8, 2012 I couldn't resist getting my hands on one of these AP-15001D's to test out the 1500w claim. I've been around car audio since the late 80's and come from the days when you paid several dollars per watt, while this amp promises 10c per watt! Those who don't like watching videos, here's my results at 14v: 4 ohms = 504w 2 ohms = 844w 1 ohm = 1115w I have a complex test bench fitted with wirewound resistors for the ohm loads, (2) 100A 13.8v power supplies "strapped" (showing 14v), SMD DD-1 for 1% distortion measurement, Velleman HPS50 o'scope for visual display of waveform and wattage measurement (or Volts RMS at 1 ohm), Klein Tools CL2000 True RMS Clamp Meter for measuring DC Amperage pull from amp, Fluke 85 III multimeter for verifying ohm loads, 40Hz test tone from DD-1 disc, Yamaha RX-V670 receiver as pre-amp (has large analog volume knob for precise adjustments) and iPod Nano 1st gen with Wolfsen audio chip and DD-1 test tone loaded in Apple lossless format. I've seen many people "clamp" test this amp and get 1500w or more. Truth is, if you are using a speaker as the load, you must take into account phasing. If you don't know what I'm talking about, , former Rockford Fosgate engineer and the one who developed the infamous T15kW amp.As I mention in the video, I only tested this amp on the bench with resistors, didn't give it a loaded down subwoofer test. I'll do this in the future and also test 1/2 ohm as many are telling me this amp can handle it. We'll see...

Kranny Posted October 8, 2012 Report Share Posted October 8, 2012 probably does 1500 at 16v then Link to comment Share on other sites More sharing options...

Chris Hammer Posted October 8, 2012 Report Share Posted October 8, 2012 But all the internet people say its over 1500w. ... . . on another note too bad you cant test at 16v...it says 16v on the front cover..do they expect people who are cheaping out on an amp to have an dedicated 14v system?? MY BUILD *****http://tinyurl.com/gmcbuild***** Vehicles 2005 GMC Canyon CB1000r - Currently where any future funds are going.

WillistonAudioLabs Posted October 8, 2012 Author Report Share Posted October 8, 2012 But all the internet people say its over 1500w. ... . . on another note too bad you cant test at 16v...it says 16v on the front cover..do they expect people who are cheaping out on an amp to have an dedicated 14v system?? I know not everyone has time to watch a 10+ min video, but I did address the 16v rating. I got 1274w estimate using my efficiency at 1ohm and substituted 16v for 14v. Again, this represents a resistive load on the amp and similar to testing methods performed by the Car Audio magazines since the late 80's See my videos on YouTube http://www.willistonaudio.com Many tests and demos of OLD and NEW SCHOOL car audio gear!

n8ball2013 Posted October 8, 2012 Report Share Posted October 8, 2012 basically with the resistor it was best case scenario is whta you are saying.
