lutkeveld Posted January 12, 2016 Report Share Posted January 12, 2016 Can you explain why though? Just trying to learn. That impedance affects output is logical to me, but I don't see what cabin gain changes for the amplifier. Quote Link to comment Share on other sites More sharing options...
MotorCityFats13 Posted January 12, 2016 Report Share Posted January 12, 2016 (edited) cabin gain and impediance rise play a huge factor Uh what? Why would cabin gain play any role in amplifier output? in the video tony D made when the amm1 was just rolling out he explained so much things including testing with a window up/down.... doors open.... everything would change the output and power factor..... remember this is a real world test.... everything plays a roll in the outcome a box and amp in your car might make 500watts and in another car make 600watts just from the cabin size and acustics Edited January 12, 2016 by MotorCityFats13 1 Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted January 12, 2016 Report Share Posted January 12, 2016 Still seems stupid low. You sure your doing it right? There's only about 3000 of us that use the amm1. It's accurate. If used correct. Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Wicks Posted January 12, 2016 Report Share Posted January 12, 2016 Impedance GREATLY varies with frequency. Here's one of my XL12's just raw. 35ohms! Here is my system impedance with the doors closed: Again with the door open. Big difference between all the difference scenarios. 2 Quote This post sent with 100% recycled electrons. 2004 BMW M3Mechman 280A 2 - XS Power XP30001 - XS Power D375 500F of Maxwell SuperCaps (soon to be 1000F) iPadMini2Dash mounted O-scopeAudison bitOne (Remote DRC MP) Highs Amp - PPI Art A404 Hertz HSK130 (HSK165 waiting...)

audiofanaticz Posted January 12, 2016 Report Share Posted January 12, 2016 200 watts from a 600wrms amp @ 1 ohm that has a 2 or 3X impedance rise seems normal to me. Its a huge shell shocker for people that "clamp amps" and say look at my 600wrms amp making 1400 watts rms because they never measure how clean the signal is and the amp is clipping so hard the mosfets about to explode. 1 Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted January 12, 2016 Report Share Posted January 12, 2016 But 27 watts ? Lol. Amm1 in the deck for the win. Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Kyblack76 Posted January 12, 2016 Report Share Posted January 12, 2016 My amm1 shows imoedance at test. ?? What does your run tell you op? Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
audiofanaticz Posted January 13, 2016 Report Share Posted January 13, 2016 But 27 watts ? Lol. Amm1 in the deck for the win. I wouldnt expect anything spectacular out of it 130watts bridged at 4ohms. Toss a 2-3X rise to that, your talking 8+ohms, so seems right to me. 1 Quote Link to comment Share on other sites More sharing options...
ROLEXrifleman Posted January 13, 2016 Report Share Posted January 13, 2016 If I get a chance this weekend I'm going to toss a little soundstream on my resistor bank then on a sealed sub I have. Then compare the numbers just for kicks 2 Quote Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
mothra Posted January 15, 2016 Report Share Posted January 15, 2016 i have an AMM1 and have tested several amps. I have just chalked it up as a BS tool. I've tried different wire sizes, different subs and all results were horrible. I metered the Sony radio with the "built in amp" and it yielded 1 watt on a 4Ω speaker then I put a 2Ω JBL speaker and it yielded 1 watt. I metered a Soundstream 2k and it yielded 500 watts on 2 DC Level 4 D1 subs wired to 1Ω. I tried one sub wired down to .5Ω to account for any sort of rise and it yielded 300 watts. these are just the most disappointing results. There are very few AMM1 owners as a whole so it hard to get any sort of trouble shooting or support. Since I install for a shop I thought I'd use this heck out of this thing but I can't b/c it simply just doesn't do what it's suppose to do. just simply reading voltage is a failure unless you get the exact wires with the exact polarity correct when probing for your reading. if polarity is backwards on a normal DMM it'll just put a "-" to indicate the probes are backwards while the AMM1 just displays nothing so you don't even know it's backwards, you'd just assume it's the wrong wires.
