One notable issue with this McCauley AC288 subwoofer is that it has an aftermarket input connector. This connector isn't firmly attached to the backplate, but it is securely connected to the wires going into the speaker cabinet.

To use this McCauley AC288 subwoofer, first connect it to your audio system using the input connector. Make sure all connections are tight to get the best sound. When using, keep it in a dry and cool place to avoid damage. As for the aftermarket input connector, be careful when handling it because it's not firmly attached to the backplate. Don't tug on it too hard. For maintenance, clean the speaker cabinet regularly with a soft, dry cloth. Check the wires connected to the input connector from time to time to ensure they're still secure.
