I dunno....I originally had just the one kenwood and had the amp bridged. A year later I decided it was a good idea to buy a matching kenwood sub off ebay to utilize the 2 channels, and got a new box. The sub I got was used and had an obvious repaired tear in it, and was slightly bent. h: It sounded OK for a year and it finally went this past spring....the other store bought sub is still bumping (3+ years old)

Basically...right now I have 1 working sub and 1 disconnected sub in my box....and getting two new ones for cheap would be the quick fix before the end of the month.:happysad:
