I have an avic n4

Hey guys, I'm really new to car stereo and need some help. I need all the wire, fuses and distro's for my install. I have a couple sundown amps, the 100.4 and the 1000d. For speakers I have a set of components and an Fi Q sub. I'm also looking to upgrade the big three and add a 2nd battery. What do I need to complete the install? I'm looking to purchase this stuff from knukoncepts. Thanks in advance for the help guys. p.s. The install is in a bmw so the stock batt is already in the trunk.
