Testing the Right Amplifier for Your System

While shopping for an amplifier we need to consider that all power ratings are not equal. The low-quality brands will try to exaggerate lie about the power output of their amplifiers. This is always advisable to stick to good reason to stick to well-known manufacturers. 

This is the only true measure of an amplifier's power and is the continuous power rating or R.M.S. rating. R.M.S. is root mean square and is the power amplifiers average power output. An even better method is the CEA 2006 standard where in all amplifiers do not adhere to such a testing method. This test is done at 14.4 volts with a four ohm impedance load. The entire audible frequency range, 20-20kHz is tested with  distortion level of 1% T.H.D.
