The sound of this speaker will be distorted because there is no partition for separate speakers. Enclosures are not airtight, mica is not the speaker material. Nice speaker but will not play well.
Please don't think this thing can deliver 60W x 4. The max RMS Output Power with 10% distortion will typically be at around 25-30W per Channel, but only when you power this thing with a 12V Transformer that can deliver up to 180~200W. Use a rectifier with big Filter capacitors between the Transformer and the Car Radio to make smooth DC Voltage. Due to the 10A Fuse at the back of this Car Radio, the Power Consumption can be 138Watts when the Voltage is 13,8V. When you decide to use a Switch Mode Power Supply, be sure that the SMPS can handle fast and high current change. The Audio Amplifier Chips (often TDA Series) in the Car Radio are able to draw high current peaks up to 10A and more. I use a 400Watts 13,2V Halogen Transformer with a fan cooled 35Amp rectifier and a 2F Capacitor to power my old real 4x50W / 2x100W SEPP (Single Ended Push Pull) Class AB Car Amplifier at Home for my Kickbass Subwoofer that is used with my 7.2 Ch Home Cinema System that has only Subwoofer Preamp Output. Everything is shaking and it feels like an earthquake.
