Question about Car Audio & Video
Does the main amp run really hot?? can I use the sub amp on a different brand of amp as the powered amp and subs??
Need the full description of your audio setup including manufacturer and model numbers and how they are installed.

What kind of deck to you have? Sometimes there's a setting for the subwoofer output that has to be turned on. How is the deck hooked up to the amp? Be sure of the normal things: -Make sure the sub is connected in side it's box -Make sure the RCA cables didn't come off the deck -Check every connection! Let me know and be sure to leave feedback or I don't get paid.

SOURCE: apline mrv-1000 2 infinity sub
RMS power at 12V 20Hz-20kHz
2 x 100W @ 4 ohms (0.08% THD)
2 x 200W @ 2 ohms (0.3% THD)
1 x 400W @ 4 ohms bridge (0.3% THD)
That amplifier is not 2 ohm mono stable in bridged mode (assuming subs are SVC 4ohm).
It is seeing too much resistance and overheating. Thermal overload protection kicking in.
The phase switch allows you to switch from in phase to 180* out of phase. This feature is not to taken as written in stone. In some rooms, or locations of a room, the output will sound louder/better either in phase or out of phase. So there is no correct setting. It all depends where the sub is located and the acoustics or shape of the room.
Phase is term that describes multiple characteriscs and behavior of a speaker system.
Phase alignment: The vertical alignment of the voice coils of all the speakers in a speaker cabinet, so that all signals reach the sweet spot at the same time.
Crossover phasing: If one or more crossover slopes are of a different slope, then the speakers would not fire at the same time, causing delays in response.
Reverse polarity: You may reverse the polarity of a speaker to make the speaker fire inwards instead of outwards to improve alignment with the other speakers in the system. This is very common in tweeters circuitry. As for woofers, if the polarity is reversed, there is usually a cancellation of bass, to a degree.

Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.
