where the hell do you find these specs at dude? the 1210d has an 80 amp fuse same all the way back to the 05 series, the 1600 series all have 140 amp fusing the 2000 has always had 200 external fusing as a MINIMUM as per the actual manual. until you have benched 1 and can prove anything, you shouyld just shut the **** up now. maxxsonics has many amps out that are rated dynamically ( peak @ 14.4 voltage ) but since you have no real understanding of the retail marketing of a company you wouldnt have a clue how many other companies do that either eh......also output stage and new power supply designs dramatically impact actual output, the old A/B class fuse x voltage math has no bearing on new d class amps, but i guess since you know everything you knew that too huh?
