Aftermarket stereo hiss and poor FM reception

turtle64b

Any resolution on this?!

I bought a 2011 Z with a Kenwood aftermarket head unit already installed. I lived near Seattle after I bought the car, so I received enough radio stations to fill the 6 presets on the radio. I have recently moved to small-town Texas and that has changed.

I get one radio station nearly perfectly. All others, yes, all others, are either static or do not come in clear enough to discern anything. My wife's car gets maybe 30 stations clearly.

I think that it may be the FM booster? but I am neither certain on how to confirm this, nor do I know how I could resolve it.
