amplifier gain setting question

[basshead601 2]

i was reading the tutorial and i see where i did a few things wrong, mainly setting the gain where i usually listen to my music n stuff. what i wanna ask is as far as using the test tone to set it i NEVER play cd's in my radio i always use my mp3 player via aux port. it plays WAY louder then my cd's do so should i set it that way or only do it by cd? next as far as setting up the bass boost before setting the gain i see it says use the center of 45hz( thats the center on my amp) do i use a 45 hz test tone too or still use the 50? also WTF do i set "Q" at?

Most headunits have a correction for different inputs, if not then definitely play a test tone from your mp3 player to set your gain

as far as i know, when you set your gains and use a mp3 player via AUX input, you should set it to the max, then set your HU to where you think you hear no distortion, at that point start moving your gain up.

when you use test tones, make sure its 50hz, thats the usual sub sound, i heard of people using others, but if your just doing a basic sub setup, stick with 50hz 0 db mp3

turn q off or to the lowest setting

if anything i said is wrong please correct me SSA members

You couldn't use 50Hz on my system, I LP lower than that. To me that is midbass not sub-bass. Of course I could turn the filters off and use it, but dangerous recommendation as it can surely be in the crossover region.

agree, your setup I bet is more tuned since it requires lower frequencys. For a basic setup i think 50Hz is alright.

well the aux has a volume too ranging from -8 to +18db which i usually play it around +13
