I am looking to upgrade the Speakers for my 2018 Karoq with Columbus Head Unit. I understand that they are 165mm Speakers with separate tweeters, what I don't know is what impedance they should be and if I will need any spacers or other fitting accessories. I will start with just the fronts and see how it sounds before adding to the rears.

Any info or suggestions welcomed.

Thank you,

Keith

Hi, before you spend money on to new speakers I would recommend to start with sound insulation your door. It make really big difference. I have used in my octavia in all doors silent coat sheets and some sound deadening foam.

If this won't be enough for you, than try new speakers.
