[QUOTE="shizzzon, post: 8606231, member: 590338"] They have been done.. The Dyno isn't the only thing that can measure output. The Taramp's Bass12k has been tested up to 13,000w @1%THD and 14,100w distorted. Us personally are looking into start testing ampliifer above 1200w. We finally, after 2 years, are done testing lithium cells to determine what we will use in our own vehicle.. and on our test bench. Right now, i'm trying to determine what i can use these cells for BESIDES just testing amplifiers before i import more of them for everyone. Once i figure that out, i can show off more results. Our test results of some amps are already posted on this site. Here is sample of our testing- [IMG]http://i303.photobucket.com/albums/nn147/shizzzon/8ohm-30hz-12.88v-81.8f-clean_1.jpg[/IMG] In here, we set everything to max to get the maximum True RMS Wattage value but it also holds all other values to max too so we must look at the bottom on the Spectrum Graph to obtain the realtime values for this given test. With this, we are able to provide the following per test- VA True RMS Wattage Power Factor AC Voltage AC Amperage Impedance Frequency Duration since start THD % DC Power DC Voltage DC Amperage Duration since start Efficiency (calculated) Maximum values Realtime values Signal Quality Graph Spectrum Graph for Volt, Amp and Power In this test, this was done on a Taramp's DSP-3000 2ohm version. Given here, we see- 94vAC 12.5aAC 1170w DC- 1345w DCa- 103.2A DCv- 12.88v (14.3 was max before the drop. verified with spectrum graph below) THD- 1.2% Frequency- 31Hz Impedance- 7.5ohm Efficiency- 87.0% Temperature- 81.8F (verified with probe) Amplifier rating from buildhouse- 1142w 1KHz THD- 5.3% Impedance- 8ohm Temperature- 78F Voltage- 12.6vDC So, as you can see, testing shows it to be pretty close. 0.5ohm lower, 0.28v higher, but at 30hz also which is much harder than 1KHz and our signal was virtually clean. Let's add some distortion to the mix and show how Taramp's does over rated- [IMG]http://i303.photobucket.com/albums/nn147/shizzzon/8ohm-30hz-13.0v-78.1f-3.7thd.jpg[/IMG] This is with 3.7% THD, still lower than 5.3%. Still 7.5ohm vs 8ohm rated. We are now at 13.0v vs 12.6v rated and our temperature is 78.1F, which is dead on with rated. Now producing 1,320w of power which is almost 200w over rated and still not as distorted as rated. We have similar results of other powerful amps tested at high impedance before we can test at lower impedance once our lithium cells get here. [/QUOTE]
