That looks like it will work nice. I did something similar, added a 5 channel amp, 4 new speakers and a sub in the trunk. Kept my factory head unit, so it looks clean, and like its stock. Out of sight, out of mind when I go downtown. https://www.allfordmustangs.com/forum...ml#post2610234
If that is the amp/processor you want, you might do a search of its part number on Google. Crutchfield always gets beat on price.
