I think it has to do with design, and where it's fuse, power supply or speaker outs.

One of my Pioneer amps thats rated at 600 rms, uses an 80 amp fuse.

I've noticed over the years that about 8 amps of fuse for every 100 rms watts, for your average quality amp.

MB Quart ONX1.1000D has 1, 70 amp fuse but claims to output 1000 watts

can you name one 1000 watt rms amp that will only pull 50amps of current without popping the fuse. because I want it!

there was a discussion on this before, most of them was cheater amps btw and only had low fuse ratings... also some of the fosgate railed amps are like that

I've got 2 older amps in front of me and neither of them even have fuses atleast not external. Orion hcca 250 (800x1@12v) and crossfire vr1000d (1000x1@12v).

pop them open and check the internal fuse

IIRC that Orion is a cheater amp and does way more than rated?

there isn't one in the orion. Dont have any tools around to check the crossfire. Here's some pics of the orion. It is beat http://www.caraudio.com/forums/amplifiers/542199-whats-old-school-orion-worth.html

Ya, its rated at 2x50, but will do 800x1 at 12volts. Of course that is with the harness for bridging

so around 1000-1200 at 14.4v lol
