I am new to the car audio scene and have been researching how to add an amp or two while retaining the factory headunit. I see that many people on here are using something like this http://www.amazon.com/gp/aw/d/B002T4XR78 to add rca outputs.
I was speaking with a buddy of mine that did his and he used a couple of these for his setup. http://www.amazon.com/gp/aw/d/B001EA...AC_SX110_SY165
my question is what is the advantage/difference between these products?
Would the PAC units be sufficient to get a good amp/speaker combo going?
