Newbie to the SKAR brand.

I bought this online because I wanted a nice sound system without breaking the bank. Only thing I regret, was not looking into this brand much sooner. I totally love my setup and YES would definitely recommend this brand to anyone!!


This is what my 2016 Mustang needed. Clear deep bass. My wife was like wtf is that, bahahaha. Bass shaking the house.

Great product

Five stars


I ended up switching to the dual 12” subs but they are amazing


Dual 12’s are the shit. Definitely slam hard
