SpinSub TroubleshootingUpdated 3 years ago
Make sure the volume is all the way up on the SpinSub and place your hands near the speakers (left and right side). Do you feel any vibrations?
If you are inclined, we've seen a few cases where the connection to the speaker came loose. You can unplug the power, then remove the 6 stews on the amp. You will see a white clip that should be all that way on the pins. The clip connects to black and red wires that go to the speakers. We've seen this come loose during shipping.
