(MY SETUP IS BELOW) So I started the distortion test on my head unit and found that one of my RCA outputs was bad so I had to replace the Line Output Converter. After replacing the LOC I found that my head unit clips at 26/32. Then I went to set my bass amp, set all the settings on the amp like the manual specified and started to turn up the gain on the amp and immediately it found distortion somewhere before the first notch mark. That's not even 1/28 of the way up. Not to mention that the DD-1 only detected a signal and not the 40Hz yet. So I shot down to the Best Buy and bought a Kicker DX10001 amp to see how that stacked up against the Alpine and to no avail I ended up with the same result only this time I was able to turn up the gain a little more then the Alpine amp. Has anyone experienced this with any of there amps?
I eventually had to set everything up by ear "once again" until i can afford an oscope to insure there is no clipping.
I went to Alpines' website and somewhere it states that with there new technology it lowers the amount of distortion i.e. their claim is they have distortion within their product. Anyhow, my suggestion to anyone who decides to by an amp is stay far away from Alpine and Kicker Amps and invest a couple more dollars on some quality products.
