Hello municipality, I have a C70 convertible and want to retrofit the subwoofers in the backrest of the rear bench. They are equipped with Dolby surround series. Apart from the heavy price of the Dynaudio chassis, I would like to know if the subs can be easily connected to the final stage of the series. Supposedly it is an optically simple Alpine V12 where the outputs are intended for the subwoofers. Does anyone have experience with it? Or another idea? Thank you Borsti
