MeanGreen03 Posted July 22, 2010 Report Share Posted July 22, 2010 I have a Rockford Fosgate T1500-1bd & T600-4 and I need to know the output voltage to set my gains properly. I can't find this information anywhere... Link to comment Share on other sites More sharing options...
dugee81 Posted July 22, 2010 Report Share Posted July 22, 2010 What impedance are you going to be wiring your amps to? And what's the RMS at that ohm? Edit: well assuming you'll being wiring your 1500 @ 1ohm, and the 600 @ 4, you would do watts * ohm (1) = 1500, then find the square root of that which is 38.7 volts AC. If the 600-4 is 150wrms @ 4ohms, you'll want to do 150 * 4 = 600, and the square root of that is 24.5 volts AC 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm Link to comment Share on other sites More sharing options...
MeanGreen03 Posted July 22, 2010 Author Report Share Posted July 22, 2010 Ahhh, ok.... Well I'm actually running the T1500 @ 2ohms (1000Wx1 @ 2ohms) so that would be 1000*2=2000, sqrt(2000)= 44.72V AC. Im running the T600 @ 4ohms (100Wx4 @ 4ohms) so 4*100=400, sqrt(400)= 20V AC. This is correct, right? Link to comment Share on other sites More sharing options...

Freshman6969 Posted July 22, 2010 Report Share Posted July 22, 2010 yeah, so the formula you were just givin is the "quick way" to do it, with a DMM but its not the best way but it does work, the BEST way to do it is with an oscope but those fuckers are expensive! Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?

NO KIDDING!!! I was trying to scoop one of those up on ebay for cheap, and well, they weren't too cheap!! Link to comment Share on other sites More sharing options...
