Perfect fit

I couldn’t hear my stock 3.5 speaker at all so I upgraded to the infinity and the sound is so pure and clear

Sounds amazing

I had a faulty stock speaker in my Mustang Mach E and this replacement is just what the Dr ordered. Perfect fit and super easy install.

Sound way clearer and better then the stock ones that were in my truck. Could see a big difference in weight too, and how much bigger the magnet was from the stock ones ????????
