Waffles

Hello! I recently rescued a couple year old klipsch system from my brother's basement. I have wired everything up and so far am extremely happy, but I have never gotten the subwoofer to really work. After doing some research sounds like the BASH amp may be blown on this? I am not very speaker inclined so I attached a video if someone can confirm that is the problem. Or do I have my wiring/ input/ voice coil issue. SW-110 popping noise
