You said 2 sets in your original post which is 4 speakers.
Can't seem to find a kit with everything you'll need right now but basically you'll need
-a run of 4AWG power cable with an ANL inline fuse (6 metres should do it)
-two 4AWG ground wires (one for each amp)
-a distribution block which will take your 4AWG power wire from the engine bay and allow you to split it to two 8AWG power wires (one for each amp)
-couple of short runs of 8AWG power wire for the above
-remote cable which you'll daisy chain from one amp to another to turn them both on (again about 5 metres)
-couple of decent RCA cables
-however much speaker wire you think you'll need
I'd think it wouldn't take someone who knew what they were doing more than 3 hours to do it tidily and safely.
