Evening gents! (and ladies) Soooo after quite a while of trying to code the *** into my car I think it's time to pull the plug (literally). After trying for a while myself (and with the help of others) I took it to an Audi specialist and they recon that as the MMI unit is a different version to those who have pictured doing it successfully, it can't be done. Anyway, moving on. I'm still looking to install the *** sub and amp it independently. A couple of guys said they have had success in tapping into the rear speaker cables, but others has said this may cause problems resistance-wise. Can anyone advise on whats best to do? I'd look to power it with the 12v supply in the boot, I'm wondering if it's easy to tap into Cheers in advance!
