Blown speaker

Well to make a long story short, I gave my tdi to a family member for their road trip down south. I thought, sure no problem take the tdi, and I assumed that because they were family that they would not abuse it.*roll your eyes if you wish* Well I get in the car today and turn it on, I hear a faint crackling, upon further inspection, turning up the radio, I notice that they blew the speaker in the passenger door.

I don't want to take it to the stealer ship and have them replace the speaker, nor do I want to go after market, I just want to replace the one speaker for now. My question is that I have a monsoon system, and I would like to know if I can take the speakers from any jetta/golf and use them, or if I have to find speakers with a monsoon system (I plan on going to a large auto recyclers tomorrow and see if I can get a speaker for the car).

You need to find Monsoon speakers. Regular speakers are different wattage and connectors.

Yeah, and the problem is that you have to really do quite a bit of work to replace them. On my 03 that you see in my avatar, I put MB Quart aftermarket speakers in, and what a pain!!! You have to drill out four rivets just to get the speaker mount out. Of course, since I did aftermarket speakers, I had to fabricate new mounts. What a hassle... If you have a rivet gun, and the time, finding a good used speaker should be fairly easy...
