[QUOTE="OldFartAudio, post: 8712989, member: 680592"] I agree with this, the object of setting the gain is to maximize the performance of the amp without going over. Watch some videos and you can see one amplifier having different maximum levels between channels. Setting gain based on ratings is only gonna get you in the ballpark and it is only gonna do that if the amp is rated accurately. If the amp is underrated you are giving up potential and if is overrated you are gonna send out a clipped signal. I have seen a guy set a subwoofer’s gain using a full range speaker with a capacitor inline. He stated that the distortion would create noise above the subwoofer crossover frequency so turn the gain up until the full range speaker makes noise. Then slowly back it down until it stops. It only works for speakers playing frequencies lower than the distortion tones though. As for the best method an Ō scope is the most accurate way. I would even say setting by ear would be better than using the ratings, especially if you are running a “more affordable” amp. [/QUOTE]
