Dual Power
can i use 2 identical amps to power 1 dual coil sub?
i have a dual coil sub & 2 identical 500 watt amps. the sub is 1000 watt rms. can i use 1 amp per coil. the ohms all match.
YES YOU CAN!
You must match the amps perfectly- down to the millivolt.
use a multimeter to read the volts coming out of the amp's speaker wires.
Turn the gain knob until you reach the same voltage output on both amps.
Use a bass cd so you can play one specific note to your amps.
(repeat a 35hz note or something)
most people match their amps at a very low volume level. Remember, i said "millivolts" not "volts". If the amps are matched down to just a 1 volt variance then you WILL blow your sub very quickly.
When you think you have them matched- Test the voltage at different volume levels once or twice to make sure they are the same or are very close. a couple millivolts difference is ok.
