It was back in the day called a "cheater amp" actually pushing ALOT more than rated ... If you go back a few years ... Cheater Amps were the reasoning for all those power classification changes in the mid 90s ... Amps like US Amps, Punch (rockford Fosgate), Linear Power, PPI, and especially Orion HCCA Amps ... So it wasn't 45w..... when was the TL first put into official use?
