Yes, I have My Temp and Dual. On My Temp both sides are either full hot above 71 or full cold below 71. With Dual turned on, the passenger side blows hot at 74 and driver side is cold at 71. It was that at 71 it was warm and then cooler at 70. Now it is either full hot or full cold on either side of 71.

Sorry, should have stated specifics. I have a 2015 Fusion SE, 1.5 Ecoboost. I'm figuring it has to do with whatever regulates the airflow doors, but don't know how that works on new cars. I'm from the days when you pull out the vacuum motor, stick a new one in, problem solved.

When using the heater, any temp above 71 degrees blows full hot air, and under 71 blows full cold air. Any suggestions on this? I have not tried the A/C yet, but probably need to check it.

I ended up at Car Toys and came out with Alpine S-S65C. The pair was on sale, reg. 169.99- sale 119.99, and by buying the second pair it was half price, 59.99. I purchased an Alpine amp MRV-F300 75W RMSX4. If you are familiar with this, do you think it was a good choice? Just your opinion, and I know everyone is different, Have not had time to install them yet.

I installed a 10" Rockford-Fosgate sub with an 1100W Boss amp in my 2015 Fusion SE. I want to upgrade the door speakers, but there are so many choices. Any suggestions as to the best speakers for the money? Willing to spend $200 to upgrade. Walmart Online has many brands of sets if 4 speakers, but considering I am a musician and audiophile, I am fairly picky about sound. I like to hear AND feel the music. If I listen to Van Halen, I want to feel the speakers hit me, but not blow my eardrums out.
