Don't know exact reason but maybe
"Amp"lification, "Amp"-lifiers
I think there's an expression when you're excited you're all "Amp"ed up
The launch of Amp in LA
http://en.wikipedia.org/wiki/KAMP-FM>>Previously, AMP Radio was heard on KCBS-FM HD2 and also streamed online...The station had targeted teens and young audiences by playing a mix of popular child friendly artists such as Miley Cyrus, the Jonas Brothers, and songs from the High School Musical soundtrack and Top 40 artists (Chris Brown, Paramore, Rihanna and Metro Station). With this, CBS Radio eventually looked at moving the AMP Radio format to mainstream radio because it felt that was more cost-effective than the talk format. Eventually, AMP more closely resembled a more mainstream Top 40 format and it was advertised the station on many of the company's radio station websites. Finally, it was launched on KLSX. The company stated that testing AMP Radio on HD 2 and online showed brand loyalty and the success of the format.
It also goes on to say many felt the station was launched in an attempt to go after the #1 station in town, KIIS (Kiss). Sound familiar?
