You have to have an alpine head unit.
the 4 speakers at front split with y rcas would throw it off. needs to be able to tune each channel independently.
rear channels on HU would also mess it up. (i think?)
Im sure pioneer makes something like Imprint.
My Pioneer 880prs has a mic with it that dose everything imprint dose, i don't like the sound when its done. just use it for T/A
