    I am buidling amp racks that can be pulled in and out without having to unwire the amps. Setup is for three amps that will be mounted to the back of my regular cab tacoma. Want it to be a plug and play kind of deal One Rack will have the MCA3004 on top and the MCA2004 on bottom, and the other will have the MCA1400 on the top with my satelite, and alarm under it. I need connections for the 4awg/8awg power and ground wire aswell as the 8awg sub wire.

    This is what I am in need of, (2x) 4awg to 8awg single in/single out, (2x) 4awg to 4awg single in/single out, a 4awg single in w/ double 4awg out. I also need (2x) 8awg to 8awg single in single out. All without fuse holders. I just need terminals as the whole setup will be fused externally.

    This is what Im looking for terminals/distribution block wise.

    I will be running a stinger circiut breaker before all of these. Instead of an AUG fuse holder. Which breaker should I use amp wise? 80/100/135/150/200/240? I will be running the memphis MCA2004 (1x40amp), MCA3004 (2x25amp), and MCA1400 (5x30amp). From what I read if I go by the amps I will need a 240 amp circiut breaker but if I go by the wire all I need is 150 amp circiut breaker, so far others online say go by wire dia. and not amps. But I dont know, should I do two sperate breakers instead? One for the AB amps which would be a 100amp and one for the D class which would be 150amp?

    These are the circuit breakers I will be using in place of doing an AUG fuse.

    you should always fuse to the wire size,otherwise wire could possibly melt before you trip your higher rated fuse

    Talked with some others and going to go with the 240 breaker. And that wire will melt is a myth. I've had plenty of installs with the AGU fuse meters away from the source and have never had a melting issue.

    What about the distrubution block. Anyone know about any?

    it can melt, im an electrician, doesnt have anything to do with your fuse, has to do with how much current is flowing and how long, not saying your will,but why risk it, your system will never pull the full 240 amps so i would fuse for 150 and if it blows go a little bigger, not sure where you saw that 4 ga could handle a 150 amps anyways, i have 150 amp breaker on my 1/0 kicker power wire
