How can you test a used sub to ensure it works and isn't damaged? Without being able to hook it in to an existing car stereo.
I've heard to hook it up to a battery and it should react but I really don't trust that theory. |

^^^^ he tells the truth.
dont forget to flip the wires backwards to test going the other way too(in and out) |

Right on. Thanks for the help.
I'm also going to asume that the cone should be able to be moved without alot of force. |

sometimes new competition subs with the massive paper cones and 3 inch coils will be almost impossible to push till they're broken-in.
OOH! IMPORTANT: you should never hear a "scratching" sound from the battery tests, or if pushing from the exact centre of the dust cap, down. but its ok if it happens when you're pushing up on the cone a but, but don't do it too hard.
if it scratches all the time, or wneh trying to push from the centre of the dust cap, then the coil is probably partially shorted or overheated. it also happens if dust gets in there. then it's hooped. |
