Review on 🚗 High-Quality Car Mid Bass Speaker System - Professional 6.5 Inch 200 Watt 4 Ohm Vehicle Mid-Bass Component Poly Woofer Audio Sound Speakers with 30 Oz Magnet Structure, 2.5” Mount Depth Conveniently Fits OEM - Pyramid W64 by Angel Scully

Literally perfect in my 2005 Silverado. I had to drill new holes as the factory speaker is clip on, but that only added about 2 minutes to the process. The positive and negative terminals are clearly labeled and the included wires were fine. Don't expect to hear those 40Hz bass notes and these are mid-bass drivers that don't have full range so they should be part of a separate tweeter component setup. Even just using the head unit with no additional amp, they definitely improved the factory sound and added more power to the bass they can produce. Absolutely recommendable and for the money there is literally nothing to complain about!
