[QUOTE="DarkKnightSM, post: 8573644, member: 672612"] I cant speak for all amps but the bass knob on my jl audio 750/1 appears to overide the gain. For instance, if memory serves me correctly, my gain is set set to about 5/8 to max. Before i got the knob, majority of songs played just fine, bass was fine, deep and low, no audible distortion as long as im reasonible. Now i added a bass knob, for the songs where bass notes were recorded at a lower volume or whatever. And with the knob all to the left, or off the sub does not move or reproduce sound whatsoever. Infact theres a point as im turning it to the right and more right, all of a sudden, bAss! So roughly halfway turned up i get bass back, usually i have the knob between3/4 max and fully maxed. Its also very easy to distort with this stupid knob. But its mostly used for lower listening volumes for when the bass volume would naturally be lower. If im at the 3/4 volume at my HU and i crank the knob to far up, its very very easy to distort. Same or similar as gain. So with this said, it appears replace the gain on the amp.
