I think that if you are capable of installing the system you can tune it. Very simple and someone can help you out. All you have to do is set the frequency to match the speakers for each channel and the adjustable gains for volume with the HU and your set. Just a couple minutes. Lots of information about this on the internet. Crutchfield has a good step by step. Once tuned you will be able to turn the volume up so high you won't be able to stand it ,HOWEVER, the signal will be crystal clear.
