Alright, so the first one we installed was dead, we just finished the install this weekend with a new Power Acoustik Capcell 400 and.............in theory the thing kicks ***! Real world testing.............not done yet, but on a Honda with a 60 amp alt. we are doing just fine, (all good so far/just dipping below 12v at idle at full tilt) as before we were not giving nearly the power the amp needed. Running a (cough) Lanzar Vibe something or other (apparently the same board as a Diamond D6 Monoblock?? 90-100 amp current draw) the thing f*n hammered!! We put it on a couple of Diamond D6 10's in a T-line box and ....holy anal beads batman the thing took my breath away!//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif
