The first is frequency response. We need to know if the signal coming from the factory radio or amplifier has been equalized or filtered in any way. Equalization can help improve the performance of inexpensive speakers and compensate for the acoustic characteristics of your vehicle. The second is voltage.

There are several competing measures of noise and distor-tion for audio systems. The most common are Signal to Noise Ratio, Signal to Noise plus Distortion Ratio, Dynamic Range, Idle Channel Noise, and Harmonic Distortion. Most of the measurement techniques presented here are based on the AES17-1991 and EIAJ CP-307 CD measurement standards.
