[QUOTE="DIGIDIGIBOMBO, post: 1033862, member: 562297"] Hi there, i have a question again:D.First to set the HU max level i must use ordinary music and when i hear distortion i lower a bit, or i must use a test tone cd?:STo set the amp gain, i put a regular music cd and pick all the bass, frequencies of lpf, hpf...that i want ok. After this i use the voltage calculations and start increasing the gain while listening to the test tone cd till i have the right voltage, thats it??? I cannot do this with a regular music cd? it must be a test tone?? for a sub i use 45Hz, and for 6x9" 40rms speakers i use 1Khz? I have a built in cross over in the amp so i must set it before setting the voltage stuff right? U said also, that if we have an external cross over we must set it at last, y?? u mean it wont affect the voltage after setting the gain? Thankssssssss a lot , sorry to many questions i know:D The test tone cd for a sub, must be 45 Hz at 0dB? [/QUOTE]
