big red power wire fromthe batery to the power cap.
red wire from the cap to the amp positive or batt
black earth wire from the cap to body work,
black earth from the amp earth or negitive
wire usually blue from the head units remote lead to the remote on the amp
phono (rca ) leads from the head unit to the amp

set up gain crossover

boom boom boom

job done

speaker wire from the amp to the sub observing pos and neg

sounds dificut but it aint the biggest prob you would have is hiding all the wires

also good idea to run power cable down1 side and phono leads down middle of other side tro save interferance

doesnt really mater about the peak power of the sub and amp just turn the gain up slowly until you hear distortion then turn it down a bit

dunno bout the active subs
