My wife and I are picking up our brand new '13 MCS on Saturday morning. The one option it doesn't have is the HK sound system so I'll probably need to make some upgrades there. I keep looking at the Integral system, but it's just time consuming and complicated to install, so I was wondering if anybody has had theirs installed by a professional? Any other audio system mods anybody would recommend that are a little lest costly or invasive? Any help is greatly appreciated.
