I'm wanting to upgrade my factory speakers, add an amp and possibly add a single sub later on to my SuperCrew. I'm keeping my factory head unit. I've come down to the Infinity 682.7 Kappa's and the 6812 Refernece's but have know idea what amp to get. I've read that I will need a Line Out Converter. Do I get a 4 channel or 5 channel amp since I may be adding a sub down the road. Any help on which amp to get would be appreciated.

Thanks for any input

 

If you're not going to go crazy with it, Check out the infinity 5761a 6ch. it stands at 56x4 +107x2 or 56x4 + 287x1 in 5ch mode.
