Again, Testing out my Kicker CVR12s with my Coustic 600SE amplifier. Unfortunately I could only run the Kickers at 8-Ohm on the 600SE, (the Kickers have Dual 2-Ohm coils) so I was not utilizing the full power of the amp, however, it still hit pretty hard, the subs were flexing more than they do on camera, my digital camera is not the best at seeing cone excursion. The Coustic 600SE amps are very powerful & pack a SOLID 600 + Watts RMS! Very Nice sounding amps! When you look at the side of the amp & at the fuse holders, you 2 20 amp fuses, the third one is a 40 amp, this amp actually uses 3 x 30 amp fuses, though I do not have any at the moment so I uses 2 x 20 amp & 1 40 amp, so thats 80 amps total, just 10 amps short of the rated 90 amps it needs, for the testing I was doing this was plenty. ust thought I would add that note about the fuses Check out my other Kicker CVR12 videos.
