FiBTLforlife Posted July 2, 2008 Report Share Posted July 2, 2008 i just installed my new Fi Bl 12'' sub and have it hooked to a memphis class D 1100RMS amp. well i did the gain my ear until i could put a meter to it and once i got the meter to it i saw that it was putting out around 45v were it should be around 33.17 for 1000RMS at 1ohm....so i set the amp to 33.17v output and turned it up and it sounded like an 8'' sub.....no loud at all. bf it was shaking everything, flex out of the world.....im also running 12g wire to it, i know its to small and i got to get 10g but will this make that big of a diff...if i get 10g wire will it fix the prob of the sub not being so loud/??????/ thanks mike Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...

If you start to smell it put gains down a click or two. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
FiBTLforlife Posted July 2, 2008 Author Report Share Posted July 2, 2008 Turn The gains back.If you start to smell it put gains down a click or two. its a gmc sierra truck single cab 1999.....yeah the amp and sub seemed to do fine and ive even had it full out for a whole song and no burning or smelling at all Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...
FiBTLforlife Posted July 2, 2008 Author Report Share Posted July 2, 2008 this is a vid i took with the gain at about 45v output Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...
audiofanaticz Posted July 2, 2008 Report Share Posted July 2, 2008 (edited) You are too use a test tone while setting the gain of an amp. They say to use a 50 or 60 hz test tone. Most amps are also rated whatever they are like lest say 1000 watts rms at a certain tone. Most the time its a higher number, higher then most people use in a daily enviorment. Same as when you see people bench amps, and they pull off these crazy high wattages, they always seem to be benched at a high freq. Try redoing the gain with a digital multimeter and a lower freq test tone. If your box is tuned for 35 hz, try a tone around 35 hz and see if it sounds louder. Ive asked many times about them gain calculaters weather they are to be rms or peak wattages, because I tried using them to set my big amps and it just didnt sound like the 3000rms it claimed to be set at on music, but when you played the tone you tuned your amp with it was loud. So just figure out your box tunning, and redo gain settings with the tone your box is tuned at. Edited July 2, 2008 by audiofanaticz Quote Link to comment Share on other sites More sharing options...

mrrairai Posted July 2, 2008 Report Share Posted July 2, 2008 FIBTL, I've tried the gain setting with the AC voltmeter deal. It doesn't hit as hard. What I did was turn it up just a little bit past where the AC voltage should be and it slams something wicked. Also big up to Semmes. I used to recruit out of Mary G Montgomery.
