Is there a possibility for premature distortion/clipping in the head unit circuitry if the amp level is too low, or are head unit outputs clean all the way up?

@saintsajid are your speakers head unit powered or amp powered?
check the leads and see if they run by a power wire of any kind this will cause EMI

Hi thnx for ur help, however it ws an earthing problem, they were not grounded thts why there ws a distortion, it is solved nw... the issue ws bad grounding! :)
THAT level is set ... ( 2 months ago by smokeymasterjedi)
THAT level is set by where your high pass frequency level cuts off ie 80HZ or 60Hz if you have a good amp(4channel)and good speakers, you can run cut off as low as 40-50 Hz its meant to meet so there is no "LOW" spot on freq. response graph

Do you tune a amp with music playing?????
i dont possibly ... ( 2 months ago by haritoma)
i dont possibly know how you can do this by ear, 1. every piece of music you listen to has differents amounts of bass and could make your sub distort easier than others also 2. what you are trying to do when adjusting your gains is match the voltage output from your head unit....this has to be done by using a multi meter or an oscilloscope meter.....

Fair enough, but i still doesnt make sense how this is correct way of setting you gains so my point still stands!

well shit the ppl that don't have the money for o-scope just gotta make do with what they got. may not be perfect, but hell, it's worth a shot. so in that sense, we are both correct. i agree this is NOT the best way haha. but sometimes it's all ya got.

No. Human audible ... ( 1 month ago by calvinblinkee)
No. Human audible frequency is around
20Hz - 20,000Hz.
Subwoofer(bass) is around 20 to 200 Hz
Mid-Range(vocals) is around 300 to 5,000Hz
Tweeters are around 2,000 to 20,000 Hz
Gain is what you use to match the voltage output of the pre-out from a head-unit
Gain is made to ... ( 1 month ago by calvinblinkee)
Gain is made to match the voltage of your headunit's pre-out. Your headunit controls the volume... Frequency is the range your subwoofer can from.

Google it.
frequency refers to ... ( 4 weeks ago by jrowe6)
frequency refers to the number of waves per second. treble is high frequency.
the amp will likely have 3 controls.
bass boost (this multiplies the gain at low frequencies)
gain (this is the volume)
frequency crossover (this controls the range of frequencies the amp cuts out from the music so you can concentrate the power on a given frequency range)
the crossover will likely control 20-200hz . if you set the crossover at 150hz the amp will only play frequencies below 150hz
some amps also have ... ( 4 weeks ago by jrowe6)
some amps also have a subsonic filter which cuts out the bottom frequencies you cant hear to save power.
some amps have a selectable crossover.
high pass, cuts out 200hz and below, this is for midrange and high range speakers.
low pass, cuts out everything above 200hz, this is for a subwoofer.
