I installed this on
Subaru Impreza

Review
I have always been reluctant to install a subwoofer box at the trunk as the boot space is important but not able to fully achieve the deep bass to complete the musical experience. My installer introduced this Esatto CO-SW10 slim passive subwoofer that only required a small and slim box, space occupied was insignificant and completed full-spectrum sound qualities that I desired. With the Esatto Comado CO-D6 DSP amplifier powering the sub in active mode, the combination fulfilled my satisfaction with the different types of music that I enjoy listening. - Sim Wen Han Merryll, Owner of Subaru Impreza WRX SLA38--Z
