Hi all,

I have a 2011 TDV8 4.4 with optional Harman Kardon Logic HD audio. The addtional HD means more speakers etc.

The strange thing is that I did not hear the subwoofer anymore. Before I had wonderful and powerfull bass in my fatty but now I mis it... Adjust the audio settings in the Logic7 menu gives no result. Where can I find the relay for the subwoofer (does it actually exist?) and where can I find the subwoofer? Is it a complete different audio system between the normal Logic7 and Logic7 HD?

I think I have to check the wires/connectors/relay/speaker or I need to buy a new speaker if it blows up (part no.?)

I have a 2008 and I'm very sure the subwoofer is in the boot behind the spare wheel recess. Not sure if they moved it on later models. Just lift the boot floor up and you should see it there.

I have a 2012 with the HD Logic 7 system and the subwoofer is located in the boot behind the panel on the left side, if you take off the removable section the subwoofer is towards the front. 2012 TDV8 Autobiography Baltic Blue
