jayblz20 Posted July 13, 2015 Share Posted July 13, 2015 Hey guys, I'm trying to install a new head unit, amp, subs ect. in my 2011 legacy 2.5i limited with HK. I am having trouble figuring out all the parts Ill need in order to keep my HK and my controls on the steering wheel working properly. Can anyone help? Do i need to find an interface, or a special harness? thanks. Link to comment Share on other sites More sharing options...

Are you going to remove and replace your OEM h/k amp? If so, you can go with a 20-pin harness with plain (or no) speaker wires instead of male RCA plugs. And you won't need the h/k amp trigger lead on the 24-pin aux harness. If you want to reuse your car's factory speaker wires (nothing wrong with doing that), you can obtain harnesses to connect to the factory speaker harnesses (2 of the ones that are currently plugged into your h/k amp). See this post for details. On the other hand, if you want to retain the h/k amp, and only want to add a new amp for subwoofers, get the parts listed in the 1st guide above to connect your new HU's main speaker line outs (RCA jacks) to the h/k amp. Then run your new subwoofer amp from your new HU's subwoofer line outs (RCAs). Link to comment Share on other sites More sharing options...
jayblz20 Posted November 3, 2016 Author Share Posted November 3, 2016 Do you still make these harnesses? I sent an email a few days ago but haven't heard back. Link to comment Share on other sites More sharing options...
