I miss the fact that you can't easily replace radios in many cars.......
On my base model I just replaced all four speakers with Focals it ain't great but it's a huge improvement over the stock kazoos. It was the 1st I ever heard of Focals I got the entry level ones in the clearance bin at Crutchfield...after considerable break in they sound good. Remember to Google "Crutchfield coupon code" normally you can score.
I will admit to not liking touch screens.
I hear ya. I miss the old days when upgrading a stereo was simple. Being forced to pay an extra $200+ on a head unit sucks too. I recently replaced my door speakers with Pioneer TS-66844Rs from Crutchfield. Cleared up mids and highs but its lacking bass. Makes me want more. Looking at headunits and posssibly a powered sub as well.
Here is the other Metra at Sonic that isn't touchscreen: Metra 99-5823CH | 2010-up Ford Mustang Single/Double DIN Dash Kit
