Attaching the same below In this case the below speaker meet requirement for components Polk DB6501 Hetz ESK165.5 Hetz DSK 165.3 JBL GTO 649C In my previous vehicle about 6 years back I just went to the shop and got a Sony HU with Aux and 6*9 Co-axial fixed on rear parcel tray along with 4" co-axial on front dash. Both speakers of Blaupunkt. Had been quite satisfied with the performance till volume level of 20. Anything over that was not good.
