I have heard
-just add it to the current wiring of the original siren
-use a relay(525T correct).
Which is it?

yes use a realy.
More than 3 = use a relay.
Most alarm siren outputs can handle the load of up to 3.
This is the usual stated rule about additional sirens.

Where can you get additional sirens??
Anywhere. Online, Ebay or your local car audio & security shop.
Do a search for sirens here & read some other threads. ;)

if ur looking for mini piezo's, u can usually get em pretty cheap off of eBay
I bought ten piezos from radio shack for less than $5 each. They are pretty loud. I paid $15 each for a pair of DEI piezos that are a little bit larger and louder. I also added a siren just like the one under my hood, but mounted behind a rear panel that had vents. I now have 1 siren on the outside, and 13 on the inside. It's brutal. I plan on adding a couple more to the outside soon.
Use a relay. Take care to tap into the existing siren output somewhere inside the vehicle where the wire isn't easy to find or access. I also highly recommend a well hidden backup battery for your alarm.
