Also , beside the actual Kundalini Yoga and other things which empowers the Kundalini and the twin snakes I recommend you some other various things AFTER THE YOGA.
Those two meditations:

You can even do both , but must be done after the Yoga, as it's more potent then , you can do one of them , yoga and then the other meditation , this will be alright as well!
Also, if you truly wish to empower the kundalini and raise it up use sexual energy , on your .. thing and mostly in the end of the actual sex or masturbation re-direct your sexual energy visualizing the red energy within the bottom of your ..thing ,yea and just visualize it at very powerful red as it expands more and more to a higher ball of energy [you can also do golden-light but personally I prefer red for this meditation] then just spine it up slowlely but gradually towards your back until your 6th chakra , every time do this multiple times from bottom to the top, raising this energy trough your spine from the bottom to the top.
I know you're question was another but I felt like sharing this as well, I hope it will help you and others. Best of luck!
