I'm considering going with no head unit beyond an iPod on an install.
I could just use the input sensitivity on the amps to permanently set the front/rear fade but is there an external solution for this? It would be nice if it had a subwoofer crossover with adjustable gain, as well. I adjust the sub more than I adjust the fade.
Of course, it will need to have volume control as well, since I intend to use a flex dock with bottom connector.
