plz someone tell me the correct way to do this....i have them strapped pushin 2 12''sx at a 2ohm load.....

This is an animated guide to ensuring your gains are safely set

http://www.jlaudio.com/tutorials/Input_Sensitivity/Input_Sensitivity.html

You basically set the output voltage on the amp to the rms voltage handling of the sub.

You're sub the SX can handle 1000watts RMS and has 2 2ohm coils

1000watts at 4ohms equals(coils in series) 62volts handling

For a pair of them wired for a 2ohm load to the amp you have a voltage handling of 63.24 volts.

So watch the guide then go for around 65volts for a gain setting.

ok i have no idea how u just got that.... i thought u set ur gains for the output volts on ur hu...ex- u gotta use volts=sr(powerxresistence) that would mean

volts = sr(2400x2)69.3 or would i do it volts=sr(1200x1)=34.6.....its 2 amps so do i set them like the were combined like the first or do i do it for just one and it tranfers to the other and evens out...i have no clue where u see ne thing about matching volts form subs or whatever in the gain setting sticky......

i would think logically that the amps should be putting out the power at twice would it would if they weren't strapped so i would set the gains to the final power you need.

sq rt (2400 x 2) = 69.3 volts AC

If the amps are strapped to work as one then you want the 65+ volts, if you just settting one you want 33+ volts. There is a way to convert wattage into voltage using wattage multiplied by ohms then find the square root of the result gives you a speakers voltage handling at a given ohm. For amps it opposite, voltage squared divided by ohms.

The guide tells you how to get the amp to the target voltage on the speaker outputs. In you're case you want 2000watts at 2ohms which equals about 65 volts from the amps speaker outputs.

i am just gunna give em the full 2400 watts... but since the gains and all settings are synced together wouldnt setting the master at 34.6 set the slave at 34.6 and both amps set to that would each produce their 2400 watts into the 2ohm load.......
