Mine had blown and I tried ordering the recommended size from bazooka audio as mentioned in the threads, but when I took it apart, it didn't fit. I wasn't interested in any fabrication, so I returned it and just bought a stock woofer from the chrysler dealership. I'm not expert, but that housing and space behind the seats is extremely tight. Taking the assembly part is extremely easy - I think it took phillips head or standard hex bits, but I believe there were only 6 and voila - it was out. Best of luck and let me know what you end up doing.
