Due to their low power requirements, and tiny power supplies, HTIB systems are designed specifically for the gear they are shipped with. There was probably a resistance/power difference in the two subs, and the receiver couldn't take it. There's not much you can do other than take it to a local repair shop, and get an estimate. As a general rule of thumb, don't change HTIB components.
