1) Check the Subwoofer for continuity - At the subwoofer, one at a time, test the terminals for Continuity using your Digital Multi-Meter; if your DMM doesn't have a Continuity test, use the Resistance, or Ohms, test and check for Resistance in the Subwoofer Coil (be sure to disconnect the subwoofer wiring before performing these tests).
2) If they test out good, hook the wires back up and test the terminals at the terminal cup or at the Amp hookup if you didn’t use a terminal, don't hook it up to the amp yet. Sometimes the wiring inside the box can be a problem if it has come loose, or isn't making a great connection.
3) If you have a Sub or multiple Subs with Dual Voice Coils, or multiple Subs with Single Voice Coils, make sure your wiring is correct by checking here:
4) Make sure there are no Hi-Pass filters, crossovers, or multi Channel switches enabled.
5) Replace your RCA cable/s with known working RCA cable/s from the Source/Head Unit to the Amplifier/s.
6) Check your Head Unit settings; make sure the Bass is turned up and/or the Subwoofer setting is turned On.
7) If you are still getting no or low output, try plugging in an MP3 player or CD player using a headphone to RCA adaptor and check for sound output. If there is still no or low output, your Amplifier outputs are probably burned out.

Unwanted bass coming out of my subs

there has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.

Amp works but no sound from sub

Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

Is it good

If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!

More bass

Run one set of RCA lines from head unit to amps if you only have one set of pre-outs on the head unit, then at the amps, use an electronic crossover to split between the two amps, and this will also allow you to control what frequencies go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.

Subs will go off the wall with bass, but not in tune with music.

hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers

No bass at higher volume

Your battery should be fine! Although the amp might not be strong enough for the sub. All you can do is check the RCA cables from your radio to your amp as these might vibrate loose when you get to 17 volume and also check the monster cable from your amp to your sub asit might have vibrated loose as well.
