[QUOTE="n2audio, post: 1232483, member: 540940"] wlmrs, ignore this - Hoss clearly has no understanding of the function of a fused d-block, And according to this... He has little understanding of power wire installation whatsoever. The fuses on the amp do nothing for the smaller wire coming from the d-block, which is the point of USING a fused d-block. It's to protect those wires, not the amps. You might want to have your prescription updated... [IMG]http://img.photobucket.com/albums/v637/Liquid_force/d-block.jpg[/IMG] Solid in, two pieces out. Your original plan is fine with the 110A breaker. Actually, you may want to go to 125A - I believe a breaker will trip the instant it reaches its rated current, and since your 4 ga wire will safely pass ~125A you may reduce the times you have to reset the breaker if you go with something larger than 110A. Just a thought. Your fuses at the d-block should be fine at 80/30. However fuses do not blow the instant they see rated current so you can go a bit lower, plus 80A is a bit high for 8 ga. If it were me I'd probably go with 60A for the big amp. [/QUOTE]
