It's not bad, but at 400 watts, it's a bit underpowered It'll be plenty loud, but the amp will distort before the speakers do, particularly if your subs are wired in parallel (as dual-driver boxes are typically wired)
Listen for distortion, and turn it down a bit if the sound gets fuzzy or static-y sounding
run them straight and dont use the cross over. One speak on right channel and the other on other channel. Then turn up amp settings 7/8 the way up and control the rest from your dvd/cd player. I recommend some monster cable which is very thick. Ground the amp directly to trunk bolts but make sure to scrape the paint off or the connection will be bad. You can also use a cap which will send battery pulses to amp much quicker.
MAKE SURE YOU HAVE A SOLID, STRONG GROUND CONNECTION BEFORE ANYTHING ELSE!!!!!
Make sure you are using the proper gauge wiring for your amp.
Is the amp set up in bridged mode? What is the impedance (Ohms) of the Rockford Fosgate 12? If the impedance of the speaker is different from the impedance for the amp in bridged mode, it WILL get hot and cut off. Also, if you overdrive the amp, the same will happen.
The amp is stable :
75 watts RMS x 4 channels at 4 ohms
100 watts RMS x 4 channels at 2 ohms
200 watts RMS x 2 channels bridged at 4 ohms
300 peak watts x 2 channels bridged at 4 ohms
Also, what model is the subwoofer? What are the specs? Is it single or dual voice coil?
You can most likely mount a cooling fan on the amp and have it turn on using the remote sensor wire. If the amp still cuts out, you're overdriving it.
First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.
This amp will not give you 1000 watts of real power. From the specs I've found, it can produce 55w RMS x 4. Bridged, that would be 110w RMS x 2. The most you could get into a dual voice coil woofer would be ~220w RMS.
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
