I ask because I use it daily and i'm think the sp4 is a good variant, but I want to use it ocasionaly with another box for burping, and 4kw with low Sensitivity 86db is not a little power for that sub ? I have 75A + 100A alternators and I can't put more power because my 1.4 gasoline motor can't load big alternators at 800rpm...that will turn it off.

I'm sure the sp4 is better than n2 or mayhem in daily aplications. But in spl aplications, n2 may be over SP4 ?

about car: hud: alpine 9831 amplifier: aq 3500.1d 1 stock alt 75A + second alt 100A 1stock bat + 2 deepcycle & 0awg cable box will tune to 32hz, space 5cf is not a problem. music: rap / hip hop / dub step; with low hits It will be used daily, and occasionally in the other box for SPL competitions. I don't know what choice is better: FI btl n2 fully loaded daily variant or AA Mayhem 15' Both are the same specs, same reputation. What choice should I do ? Or wait a few reviews about FI SP4 speakers ?
