AcIdBuRn02ZTS Posted March 1, 2016 Report Share Posted March 1, 2016 Just as the title says... Looking to see if anyone has tested output of a BRX3016 @ 1ohm... I picked one up to replace my old hifonics 2k and I'm curious if it will do anywhere near rated power on music.

Lbox88 Posted March 1, 2016 Report Share Posted March 1, 2016 Expect maybe ~70-80% of what they claim to put out for power. UBL | Build Log Link to comment Share on other sites More sharing options...
AcIdBuRn02ZTS Posted March 1, 2016 Author Report Share Posted March 1, 2016 So compared to the BXi2006d I was running previously, it should put down more clean power in theory... I've got a dd-1 on the way... amp is installed but turned down. 03' Black Z71 Tahoe 3" Lift / 315/70/R17 Goodyear Duratracs Eclipse AVN6620 Touchscreen Head Unit Hifonics BRX3016 - 3krms @ 1ohm 2 RE Auido SX 18s - 14.5^3ft net @ 30hz w/ 200^2in. port120hp Cummins 4bta Swap Link to comment Share on other sites More sharing options...
AcIdBuRn02ZTS Posted March 1, 2016 Author Report Share Posted March 1, 2016 Another question... I don't have an amp clamp at the house... Could one simply set the amp with the dd-1 and test its output voltage... then test actual resistance (ohms) of the drivers and plug the info into this chart? The chart is used for setting gain via DMM. No it wouldnt be 100% accurate but could it be done to give me an idea of what its actually putting out? 03' Black Z71 Tahoe 3" Lift / 315/70/R17 Goodyear Duratracs Eclipse AVN6620 Touchscreen Head Unit Hifonics BRX3016 - 3krms @ 1ohm 2 RE Auido SX 18s - 14.5^3ft net @ 30hz w/ 200^2in. port120hp Cummins 4bta Swap Link to comment Share on other sites More sharing options...
reedal Posted March 1, 2016 Report Share Posted March 1, 2016 No, because when dealing with the AC output of an amplifier, a DMM doesn't tell you a power factor. Plus, while you may be wired to 1ohm resistance, the impedance of the subwoofer is constantly changing as the cone moves and air pressure changes and etc.. So many factors. Buy an AMM-1, get all of the power readings you want, and prepare for disappointment due to impedance rise. Good news is you can do a frequency sweep to find your lowest impedance and that frequency is when your sub will be seeing the most power (assuming environment never changes ) SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
AcIdBuRn02ZTS Posted March 1, 2016 Author Report Share Posted March 1, 2016 So basically.... to hell with the numbers as long as the power is clean and it sounds good.

reedal Posted March 1, 2016 Report Share Posted March 1, 2016 Unless you're planning on entering competitions, yes, exactly what you just said. Forget numbers. Buy and build for the sound you want.

AcIdBuRn02ZTS Posted March 1, 2016 Author Report Share Posted March 1, 2016 Good enough for me. I was just trying to figure out on paper if it would potentially be louder then it was before. 03' Black Z71 Tahoe 3" Lift / 315/70/R17 Goodyear Duratracs Eclipse AVN6620 Touchscreen Head Unit Hifonics BRX3016 - 3krms @ 1ohm 2 RE Auido SX 18s - 14.5^3ft net @ 30hz w/ 200^2in. port120hp Cummins 4bta Swap Link to comment Share on other sites More sharing options...
reedal Posted March 1, 2016 Report Share Posted March 1, 2016 Yes, it will be. Maybe not by much, and maybe not even noticeable, but it will be. Give your subs the proper enclosure for the power that will be given to them (according to paper) and make sure you can provide enough amperage to the alt to make it as efficient as it can be (a 270A hairpin would be my suggestion at a minimum, with a group 31 battery in the rear to help buffer). Hifonics is not known for efficiency at all.
