This amp takes 0 gauge inputs. So I suggest you beef up your power wiring if you haven't. If your running this at 1ohm. You need a second battery, or a H/O alternator. This amp draws some current and if you can't feed it, it will overheat.

There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?
If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.

if your power light is on then check your preamps (sub out from head-unit).Maybe you need to turn on that output thru head unit's audio menu.Also when using dual voice coils if you wire them out of phase there will be no output
SOURCE: 1501d,, What subs should i use/
I would stick with Kicker or MTX. The best place in my mind to get them is soncelectronix.com
Just try to mach the specs as close as possible. Make sure to look at the recommendations of the subs for the size of the box and the port volume.

THE AMPLIFIER NEEDS A 1 OHM LOAD AND YOU HAVE THE RIGHT SPEAKER TO PROVIDE THIS LOAD. THE AMPLIFIERS TERMINAL STRIP PROVIDES YOU WITH 2 POSITIVES AND 2 NEGATIVES, BUT THEY ARE ONLY FOR CONVENIENCE WHEN WIRING 2 DRIVERS. ACTUALLY THE 2 POSITIVES ARE THE SAME CONNECTION INTERNALLY ON THE BOARD, AS WELL AS THE 2 NEGATIVES. THAT BEING SAID, THE SIMPLEST WAY TO CONNECT YOUR SPEAKER IS TO PARALLEL THE VOICECOILS IN THE BOX BY CONNECTING THE 2 POS. TOGETHER AND THE 2 NEG. TOGETHER THEN RUN THAT POS. AND NEG. OUT OF THE BOX AND SIMPLY CHOOSE EITHER OF THE 2 POS AND NEG. OF YOUR CHOICE AT THE AMP. IF YOU EVER HAVE TO ADD A SUB, THEN YOU WILL HAVE 2 MORE TERMINAL LEFT OVER ON THE AMP. TO CONNECT IT TO AT THAT TIME. BY ALL MEANS, IF YOU WOULD LIKE TO RUN EACH COIL SEPARATELY OUT OF THE BOX AND CONNECT THEM TO ALL 4 TERMINALS, THEN THIS IS FINE TOO, AS EITHER WAY, THERE WILL BE NO DIFFERENCE WHATSOEVER. LET ME KNOW IF I CAN BE OF FURTHER ASSISTANCE....V
