Review on Enhanced Pioneer TS-A878 3.5 Inch 2-Way Speaker System by Douglas Jakab

This was the best money I've spent upgrading my 13 CX5 sport stereo. Adding it to the dashboard changed day and night and made Bluetooth phone calls much more audible. I ended up upgrading my door speakers and adding a subwoofer, but adding it to the dash was the best upgrade of all. I also bought and installed them with bass blockers. There are no dash hits and they don't dull the sound of the front doors. I've heard this can be an issue when daisy-chained with other speakers, but bass blockers prevent this. Too bad there were no speakers in the kit, but I knew that before I bought it.
