The easiest way to think of wiring voice coils and subs is this:
Posted on Mar 17, 2008
Many amps will go into protect mode if one of the speaker wires is shorted or grounded, or if the voice coil(s) are defective. Try disconnecting the speaker wires one at a time and see if the amp still goes into protect upon power up. Likewise, some amps will go into protect if one of the inputs is grounding out. Again, to troubleshoot, disconnect them one at a time and try the amp. Next, make sure that the amp itself is not grounding. Most amps need to be mounted to a nonconductive surface. If the case contacts the frame of the vehicle, it can cause a problem. If the problem is not in the speaker wires or the input cables, the amp case is not contacting the vehicle frame, and you have checked your power, ground and turn-on leads, then the amp itself is probably faulty.
Hope this helps.

There may be a loose wire to the lights, or the power supply or amp may have a problem. Do you have the amp mounted to your sub box directly? You shouldn't. The vibrations from the bub will kill the amp in a short amount of time. If it is noticeably weaker, you should check out all aspects of the system. For instance, if you have a dual voice coil sub, is one coil open? Is one channel on the amp bad? Is half of the power supply on the amp bad? hence half the power, and no lights?
