Unless you only getting a 2 channel amp to save cost, that's a waste to just run the front speakers with 4 channel amp. You're going to get the same out put while not power the rear as well and get BETTER sounds overall? It not like it's going to that much more work since he got that 20 pin harness from SVXc.
