This is a very well powered head unit. I was impressed with the quality for the price. Seems to work very well and performs really well. the buttons are also layed out well for easy use while driving. The head unit is very easy to instal due to the way the wire harness is on the back of the unit. Although the RCA Pre amp outs are large they are of good quality. you will need more space in the rear of the unit to fit the wires and other things on the back of the unit including a large heat sink right on the back of the unit. I would recomend this to anyone building a high end system or the general consumer upgrading to CD/MP3.
I am very pleased with this product in the year I have owned it, and the only problem I have had is the sliding face, when in extreme cold conditions will sometimes jam up due to thermal expansion and contraction. Can't beat it for the price though.
i love this product it fit well in my car
