View Full Version : wiring two GNX104 subs with MA Amp

I have two GNX104 4ohm subs. What is the best way to wire them with a 2 channel MAudio Amp. It is 400wattsx1 at 4ohms and 200x2watts at 2 ohms
Is the amplifier stable into a 2 Ohm Bridged load?
To obtain a 2 Ohm stereo load you would need to purchase two more GNX104 subs and and connect them in parallel to the left and right channels. Unfortunately you only have a couple of options when driving two 4 Ohm subs with a amplifier that is not 2 Ohm mono stable. You can wire each sub to each channel, but this will limit the amount of power to about half of the 2 Ohm stereo power rating, or wire the subs in series to obtain a 8 Ohm load and brdige the amplifier. This will reduced the bridged power rating by half also. I would recommend trying it to see what you prefer.
If the subs are installed into a ported enclosure this will aid in efficiency and output. The sealed enclosures will require more power to drive them so you might want to bridge the amplifier and wire the subs in series if the subs are installed into this type of enclosure.
