[QUOTE="n2audio, post: 8337311, member: 540940"] At 2 ohms 4 awg is adequate for that amp -- not ideal maybe, but shouldn't be the cause of any problems. Knu specs that wire for 100A at 20'. So switching the fuse out for 100A is fine, and should eliminate your occasional blow fuse problem. The reason you're not blowing the fuse more often is because an amp's current draw playing music is MUCH less than the spec'd power would indicate. An amp that can do 1000-1200w at 2 ohms on a test bench is going to produce less than half that on average at full volume. Instances of output that actually exceeds ~1000w will be rare and very short term. I'm actually surprised you're blowing that fuse at all. I would guess it has to do with some degree of clipping. I've been running around 1500w rms for a few years now. I use a 100A anl fuse and it has never blown. Feeding a d-block with a 60A fuse for an under-rated 1000w rms sub amp and a 40A fuse on a bridged 4 ch doing around 500w. [/QUOTE]
