Full Range Signal?
 

Hi all,

Does anyone know if the signals coming from the stock HU are full range signals? I am adding an LC2I, to connect couple of amps and would like to start with the best source possible. I know our cars are very front speaker biased and am wondering if they will have a better signal? (would this cause phase issues?)

Info: 2013 Mustang GT, auto. The car is non-Shaker, has SYNC and I just added premium door panels yesterday (car is base), next will be the LC2I, 6 channel amp to run the four door speakers and the rear deck speakers. I'm also adding a 12" sub and amp in the trunk corner. We (my 7 and 18 yo daughters) are applying sound deafening as we go.

The main goal for the car is to have a fun car that the family can enjoy occasionally, but also take it to the drag strip 5-6 times a year and share those memories with the family as well.

Thanks in advance! Please excuse any brevity or typos, posted this from my cell phone...

Thankfully, there's an app. for that...
 

Well, I guess this was a stupid question or you guys and gals weren't sure. I found a free RTA app., I'm going to give it a try. Happy modding!
