Well, the original Monsoon speakers were pretty bad, then they updated them (not sure what year) and they're supposed to be quite a bit more durable. You can usually get them new on ebay. The only speaker you're going to be able to get to replace that and wire right in is an Infinity 693.7i because it has separate high/low connections on it.

Though if you just need it to be good for the time being, you'd probably just want to check the local junkyards. You can get them from Grand Ams too.
