ok some numbers for you guys...
(this with volume at 21 on HU, I didnt turn it all the way up because I was more concerned about getting some spl testing with it done by tweaking with HU checking where the alpines sweet spot was) My volume I usually turn up to is 23-24 range and then turning up bass knob. the alpine likes to clip past 24 I have noticed.
@ 45Hz voltage dropped to 10.60v impedance after rise was 1.22 ohms I got 80.4A * 98.6v giving me 7927.44 watts = 153.6 Sealed on dash and ZERO clipping.
the best I have got out of them so far has been the 10,033w I clamped at 24Hz
