Hi everyone. Just recently bought 2012 RRS with HK Logic 7 Premium system. Issue is none of the door low tone speaker work (I mean the bigger ones - responsible for bass). Same problem for all 4 doors. The other speakers, tweeters and sub works fine.

In result of that the only bass I have got comes from the subwoofer (which as we all know isn't great either).

I'm guessing it may be faulty amplifier?

If yes here comes the question. If I buy used amplifier dedicated for my vin would it need any equaliser / software update or setup or is it just plug and play?

Please advise - trying to avoid rather expensive dealership visit.

Thank you.

Have you checked your audio settings? Are you definitely not getting anything at all?

The Amps are pretty much plug and play if you get the correct part number or superceded part number. I have a later Disco 4 Amp in my 2012 with no issues. 2019 5.0 SC SVA (Current)
