I'm debating which amp to go with to power a 15" PPI Flat Piston. Since it's a SVC 4 ohm, I need an amp to put out power at 4 ohm only. I have a Sedona 500ix, but have a Art Ax400 to power my fronts. Should I just use the Sedona or sell that and get a A600? Is there a noticable difference between Sedona and Art amps except the art on the top lol?
