A:AnswerIf your Silverado has a Double-Din head unit from the factory it should fit just fine. You will need a GM wiring harness, Antenna adapter and a Metra dash kit for your installation. If you are not sure about installing this unit in your vehicle take it to Best Buy and they can do it for you.
A:AnswerFor the AVH-1330NEX specifically: the screen is 6.2 inches. It’s a standard double DIN size. Actual dimensions are:
W x H x D
Chassis - 7 inches x 3-7/8 inches x 6-1/2 inches
Nose - 6-3/4 inches x 3-7/8 inches x 1/4 inch
Weight - 3.3 lbs
A:AnswerThis head unit is not high-powered. I would recommend using a separate amplifier if you are going to install 6 x 9 speakers. If you do use the head unit to power 6 x 9 speakers try to by the most efficient speakers you can find. That means low wattage maybe 25 to 40 Watts RMS to get the most out of both the head unit and the speakers. Just remember the higher wattage speakers are going to require more power and the typical head unit has around 20 watts RMS per Channel. Don't overload your donkey and it should give you many years of Dependable service.
