Hey what’s up guys well I got my G just a couple of months ago and I have been trying to figure out where do I have to tap into in order to connect a 4ch amp. I want to put 2 subs and change all my front speakers and run a 4ch amp fro my fronts and a 2ch for the subs. I think I know how to connect the sub ones but the 4ch one has me confused. I was wondering if I had to buy two of these http://www.installer-parts.com/by_item.php?it=70-7551one for the 4ch and one for 2ch any help would be greatly appreciated..
