Not true. This has been a debated forever. So, 6 years ago I tested the theory. I stuck a pair of Focal's on a Pioneer HU and a pair of Focal's on an identical Pioneer HU with a JL 300/4 amp. I let them run at the same decibel overnight. The next morning (12hrs later) The speakers with the amp were not working, and one of the speakers non amped, was not working. The amp overheated, but the speakers were fine. The non amped speaker blew the VC. I added cooling fans to the amp and ran the them again. 5 days later, continuously running, the amped speakers were still going and the last non amped speaker blew its VC. I always heard, "I dont need an amp because I wont turn it up to the point of distortion." Just because you cant hear the distortion doesnt mean its not occuring.
