5 Stars because they worked out the defective issues.
The first one that showed up was defective. The speaker coil rubbed badly, and the sound was nothing short of horrible. The sent me a new one, and it has been nothing but awesome! I’m running the sub as a parallel between the dual coil, and then to my 1200W 2-channel amp bridged. The base hits like no other. This subwoofer is certainly worth it’s cost, and more!
