hi, i cant speak for the outlaw amp. i do however, own the jbl s650 and the s400.
the s400 was designed for subwoofers. yes it can be uses for front channel speakers but i have found it lacks sound quality. i find the s650 is far better than the s400. if your happy with the s400 you'll love the s650.
hope this helps
