I have a 2 year old Kenwood Excellon. Very please with it, paid $470 back then. The only complaint, the power face had a hickup and stayed closed for a week. I checked all the fuses and then one day it poped open. It's suppose to open when you turn the ignition. Other than that, a great unit. You can finely tune your system with this thing, it's awesome. I'm hoping it will break eventually so I can get an Eclipse HU put in. Now those are bad a$$!!!
