Still distorting/burning sub after tuning with dd1/cc1


Recommended Posts

So i tuned my system with the DD1 and CC1, and my amplifiers bass knob clip led still lights up a good bit saying im clipping whenever i turn the system up to normal listening volume (36/40) and turn the bass knob halfway up or more , if any less it just doesn't really beat that hard. I know the led on the knob is not very accurate, but when tuning with the DD1, the distortion led would light up before the bass knobs clipping led, so i know if the bass knob is lit then it has to be distorting, or im assuming at least. I was told that since my music source is from my iPhone Via USB and the test tracks were on CD that could be it, so i loaded all the tracks to my phone and tuned everything with the audio source being my phone through USB, no difference. 

I cant figure out why im still clipping and making the woofer smelly with proper electrical and tuning with the DD1, its like there is no distortion while tuning but as soon as i hook the woofer up and play it does, Ive got to be doing something wrong.

If i left out any info needed ill add whatever is needed, thank you!

Equipment is in signature

Well what track did you use to set everything with the dd-1

track 5 for the compromise of loud and SQ

his electrical isn't up to par with running at .5 ohms in my opinion ...... what was your setting at where was the knob at when setting with the dd-1

bass knob was all the way up, The alternator company and The Amp Lab where i got it said my electrical is okay for the 3k @.5 and the voltage is pretty stable, im going to go back out and check over everything really good with a DMM.

Where was your bass knob set when you did this turned all the way up?

and your treble and bass in the deck where were those set and did you change them after?

everything was flat for tuning bass knob all the way up

You say it was flat for tuning did you turn things up after tuning

No down, 40hz and 80hz on the hu eq all the way down, I actually tried tuning the amp with the eq like that first just to see the difference from flat and all the way down and I could turn the hu all the way to 40/40 with no distortion unlike a when flat, but I still use 36 as max volume.
