Not even used complete Alpine stereo system. Everything you need, just get a wiring kit and go. I have 2 12in Alpine bass line subwoofers in a Bbox enclosure built for a 2002 Dodge Ram and up. The box is built perfect and is super heavy duty. Also comes with a perfect Alpine MRV-V500 5 channel amplifier and a Alpine CDE-SXM145BT head unit which is super nice and has a ton of features which also has the blue interface box on the back which allows you to still use your steering wheel controls which can cost up to 100 bucks alone. Also has the dash kit for the Dodge Ram which came out of a 2014 Dodge Ram 1500. This system is super clean, looks like it came right out the stereo store, you cant go wrong with this Alpine system.
