Thanks all for your help!!!
Second part of my question is, I want this all to possibly end up on our robot cart. What do I need to make it work as a stand alone system. I would like to have this done for our NYC regional which is in about a month. But... If I actually need to invest a little more planning in it then I might just scrap it for later in the season.
So you all know I have the subs in a box already, I would probably need a head unit and a seperate battery to power it all right?? Thanks for all the input, please be patient with me.
I have been an audiophile prolly since the mid 90's but have no idea on how to do the technical stuff that goes behind it!! I'm a CAD guy not an Electronics guy!!! lol
