SundownZ71 Posted March 23, 2015 Author Report Share Posted March 23, 2015 if its showing signal, and picking up the 40hz and 1khz track, and your volume is on max, it maybe that your headunit is distortion free at max volume. Several headunits are. The volume is only at 45 out of 62... I was setting my gain at 45 because at 48 it "sounds" like its distorting on the 40hz track.

n8ball2013 Posted March 23, 2015 Report Share Posted March 23, 2015 Stop guessing you bought the tool use the tool properly.

EDIT- and what track are you using to find HU noise ? Track 1 Dude... your fucking lost.... Read your manual. If you want to find where your HU makes noise at... you need to play both the 40hz tone and the 1k. Dude.. read that lil white paper that came with that THINGY you bought...

SundownZ71 Posted March 23, 2015 Author Report Share Posted March 23, 2015 Stop guessing you bought the tool use the tool properly. Are you running your interior speakers off the headunit I'm trying and thought I am. I'm running the back off the head unit, front are on a RF-400.4 Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted March 23, 2015 Report Share Posted March 23, 2015 Its only 6 pages in.... if you got bored.. Measuring a headunit only 1. This procedure will determine where the maximum unclipped volume setting of the headunit is. This is accomplished by setting the bass, treble, ect, to zero; and any EQs and crossovers in the headunit to flat. Later, when you set the amplifier gain(s); you can reset these to where you feel the customer will set them, or where you will set them for your own system. 2. Next you need to connect the DD-1 to the headunit’s outputs. Just plug the RCA outputs into the RCA input of the DD-1. If you are using speaker level outputs from the headunit, use the included harness. Red to speaker (+) and Black to speaker (-). 3. Play track 1 on test CD, turn the volume control up until you see the signal detect LED illuminate. 4. Continue turning up the headunit and you should see the 40Hz Detect LED illuminate. 5. Slowly continue turning up the headunit until the Distortion LED illuminates, then turn headunit down slowly until it goes out. Note the volume setting. 6. Next change the track to track 2. Repeat the steps 3-5 above, this time noting the 1kHz Detect LED. 7. Now take the noted maximum volume settings from the 40Hz test and the 1kHz test and average them. This is your maximum undistorted volume setting for the headunit.

This is the case only when I'm just trying to see where my head unit distorts. Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted March 23, 2015 Report Share Posted March 23, 2015 also if your "running off the deck amp" well, ill bet those will sound like shit.. compared to the low level....

Double edit - you NEED to get a signal indication before doing ANYTHING....
