[QUOTE="deldem, post: 1361214, member: 565350"] It appears as though this question has been posted a few times in the past, but no consensus appears to have been reached regarding the correct method of setting up amplifiers. So I apologize in advance if you have seen these questions before, but rest assured that I thouroughly reviewed the majority of previous threads. My question involves 2 aspects, the gain and the frequency. [I]Involving the gain setting:[/I] I've got 2 amps one which says to dial up the gain until distortion is noted than backing off 1 step. I want to be careful with this amp, because I noted that my subs tended to bottom out (make that horrendous popping noise at low frequency, high volume) if the gain was set improperly. However, to allow for equal loading of each sub, I found it necessary to increase the gain on one channel compared to the other (bridged). The other amp said to set the gain to correspond to the HU's output. My Alpine 9853 has 2V preamp outs, so I set the digital gain on the MRV F345 to 2amps. I must admit, I'm tempted to boost this gain for volume (realizing it's my alter ego talking). [I]Involving the frequency setting:[/I] Oddly enough, compared to my old system, adjusting the frequency on this amp doesn't appear to make an appreciable difference to the sound generated (even when isolating each speaker).
