Don't do it. My Kenwood Excellon XC-858 (It's the 8 series not sure which one exactly off the type of my head) was great for the first year. But then the Mask wouldn't flip around anymore. All the fuses were fine, but it didn't flip. A week later it flipped by itself and works fine now. But... Several screensavers are not working now. There are no graphic displays anymore like the lights are out or something, but when I go into menus it's fine. Now it completely powers down by itself every now and then. Shuts off the amps and goes black. I hit the power button and it wakes up like nothing happened and it picks up right where it started. Really weird.

Anyway, get a headunit that doesn't have the power flip anything. It's just another thing that can break on it. The kenwood does have a lot of tuning capability, but how many times will you fine tune your system? Once you find something that works for you, you never touch it again. It's not worth it.
