How many watts does a Orion cs 100.2 car amp have and what does the cs 100.2 mean Is it a good one and how powerful is it I dont know nothing about this stuff so can someone please explain it to me?

If you want Orion look for the Made In USA on the side. Those are the only good Orion the new stuff is trash from china. The old red HCCA Orion The black extremes the GS and GX's are the good stuff and it's not cheap.
