it's great. the only downside is that you end up with a lot of extra males or females depending on which side you attach to the car side. since i always run amps i only need 5 connections at the most (power, ignition, remote, ground, illum) and one pack is enough for each hu. i used the female side on the car's harness (no exposed metal if i have no hu installed) so i have a 10 spare females now after putting the male ends on the 3 hus i am currently swapping around.
