Howdy Everyone!

Recently had a Basslink thrown into my 2002 explorer, and am loving it! I just got my hands on another one (freebie) and would like to know the quickest and easiest way to get this all wired up! Well if possible!

For the first install, I bought this from best buy:

What I would like to know is, what power Distribution/fuse block would be best to use to split the power between the two basslinks. A site I came across had a few, but I'm not sure which would be best to use:

As far as getting audio to both basslinks, would it be doable to take the RCA wires coming out of my head unit, getting an RCA splitter and just hooking it up to the basslinks?

Thanks in advance for any help!
