If you blow the subwoofer, there is a replacement cone kit, the Orion HCCA152CKK that allows you to easily swap out the blown/burned voice coil and surround with a new one. The replacement kit allows you to keep the magnet and basket, therefore saving money as you do not need to buy a new sub.

what a good amp that will let the sub perform to its max? thanks all.
