With all respect,reading through this thread is somewhat worrying, I understand the forum is based around advice and help but it is clear by self admission that the OP is out of his comfort zone and delving into a sector where he lacks experience, I do not appreciate the tone and backlash given when the OP was challenged on legitimate points like cable calcs etc, we as a forum are not here for step by step guide, if you want help then provide all the info requested and your installation design and calculations so we can confirm or correct them for you ....
On that note, thread closed, if the OP wishes to continue interacting on the forum then can we tone down the obvious attitude, been asked for your cable calcs is what we expect before we offer free advice to a qualified person.
