Loud Avalanche Posted July 23, 2010 Report Share Posted July 23, 2010 Hello Everyone, I have been asked to do some testing since i now own 3 of some of the best amps out there.The test consist of the Stetsom 14k2d, Soundigital 12k and the Cactus Sound Elite 12k.I own a 2007 chevy avalanche and my system is a groundpounder.My electrical is make up of 2 DC Power 350 amp alternators,8 Kinetik HC1800 amps connected with copper bus bars ,MLA module.All amps where tested using 2 DD Neo Z9518's in a 25 cft box 8 cft per sub with 260" port area tuned to 36 hz peaks 42 hz.impedance rise was around 3.2-3.4 total rise. My starting impedence is 1 ohm Nominal Stetsom 14k2d Total power was 6200 watts at 3.4 ohm i had to disconnect my MLA module because your limited to 14.7 v max on the 12v version. 14.2 v dropping 13.7 v. Soundigital 12k Total power was 10300 watts at 3.2 ohms 15.4 v dropping to 15 v. with MLA module. Cactus Sounds Elite 12k Total Power was 8200 watts at 3.28 ohms 15.4 dropping 15.1 v with MLA module.( this amp really want 16v to start with so if i could give it 16v the numbers would be better. These are my results.Everyone might have different results dependent on there setup.Testing was done in the shade with the a/c running in the truck with about 10-15 minutes between runs.All amps where setup using my hand held o-scope to make sure all results where unclipped signals.My testing where done using fluke meters. Fluke 177 voltmeter and Fluke 337a. Link to comment Share on other sites More sharing options...

basscort Posted July 23, 2010 Report Share Posted July 23, 2010 LMAO at stetsom. 1 hot and ground does 14k.... right..... good info my good sir Link to comment Share on other sites More sharing options...
Team_DC-Derrick Posted July 23, 2010 Report Share Posted July 23, 2010 Nice testing to see what it does! The only thing is different is the voltage each amp was seeing, but you can only do so much with an amp with the protection circuit ! I know SD will be my next purchase already The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall....... I just realized Steve has reach Voldemort status, over on JP's site he is the one who will not be named....."We dont speak his name over here, fearing it will destroy us" LOL not even in hush tones Link to comment Share on other sites More sharing options...
Team_DC-Derrick Posted July 23, 2010 Report Share Posted July 23, 2010 LMAO at stetsom. 1 hot and ground does 14k.... right..... good info my good sir 3.4 ohms at 13.7v and did 6200 is not that bad, if he could have kept it at 1 ohm i could see closer to 14k out of that amp The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall.......

Team_DC-Derrick Posted July 23, 2010 Report Share Posted July 23, 2010 actually i went and looked on the website, the power at 4 ohms looks almost dead on, especially at 13.7 so i guess i can believe it would do 14k+ FEATURES 14K2 E Number of Channels: 1 WRMS Power (1 ohm) to 13.8 V: 16.200 Watts WRMS Power (2 ohms) to 13.8 V: 11.200 Watts WRMS power (4 ohms) to 13.8 V: 5.300 Watts WRMS Power (1 ohm) to 12.6 V: 14.200 Watts WRMS Power (2 ohms) to 12.6 V: 8.050 Watts WRMS power (4 ohms) to 12.6 V: 4.350 Watts The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall.......

Loud Avalanche Posted July 23, 2010 Author Report Share Posted July 23, 2010 I'm posting just what I got from my current set up. If you could keep the amp close to 1 ohm I know you could get close to 14k. I have other teammates who also run the 14k. That's why there are different amps because not all amp will best in every situation. Link to comment Share on other sites More sharing options...
SounDigital Posted July 24, 2010 Report Share Posted July 24, 2010 Did you notice the impedance rise difference? It is quite interesting, the bigger the power, lower will be the rise. Link to comment Share on other sites More sharing options...
SounDigital Posted July 26, 2010 Report Share Posted July 26, 2010 3.4 ohms at 13.7v and did 6200 is not that bad, if he could have kept it at 1 ohm i could see closer to 14k out of that amp Yes, without the alternators their had a disadvantage.
