Just wanted to say thanks to Steve for the DD-1 and the guys who also helped create it. It is indeed an awesome product!
Upon tuning my equipment, here is what I have come up with:
H/U: Panasonic CQ-C9800U (Volume = 0-40) (all speakers in the car are connected to the head unit)
Before: I used to turn up my volume to 27 and sometimes up to 30
After: I just found out that my deck DOES NOT CLIP and I can max it out at 40/40...which is insane.
Amp: Digital Designs M3a
Before: I had the gain up a little past half
After: With the 40hz -15db (Track 7), I am able to tune it precisely, and given that my headunit doesn't clip, I get maximum signal.
End:
My system is now dialed in, no distrotion, no clipping, and it HITS harder!
**Note: As I was trying to tune the deck to find out where the 1khz (Track 2) maximum volume was, it did not detect a signal...and the highs were piercing my ear drums lol
I double checked everything twice to be sure I wasn't missing a step:
H/U: Everything was flat
Amp: LPF turned all the way up, Infrasonic Filter all the way down, Gain all the way down
Turned to Track 2, and it didn't detect a signal and didn't light up the 1khz led either. I tried all (3) 1khz tracks and still no luck. So I am not sure that I am 100% dialed in, but close to it. Any ideas on what it could be? Thanks guys!
