Hi. I have an A3 8V Sportback - Ambition. I have the Technic package on the car which adds a subwoofer, amplifier and a central speaker to the 8 speaker system. I found the sub performance a little underwhelming and thinking of replacing the standard subwoofer.

I am considering these 2 as they both I presume will fit in the same place as the original subwoofer.
  • Kicker 43CWRT672 (6.5" subwoofer with a shallow mount depth)
  • JL Audio 6W3v3 (6.5" subwoofer)


My question is whether I need a separate amp to power either of these subs or will the built in amplifier (which is 160W) will be able to manage? If I need an amp for the sub which one should I go for?

Thanks for all your help.
