    very loud, very clear. i have a 2021 kia k5 and they fit perfectly. loudest and clearest ive heard before. i had a kicker 10 in my truck before this is more of a bass boost than that. overall love it. the left speaker sometimes fails out but corrects itself quickly only happened twice and im using the base amp not even to full copassity. they sound great can hear them from about a quarter mile away.

    Great amp and sub combination!
    Amp puts out a punch for being so small, and the sub takes it like a champ. This is great combination that complement each other. I like it a lot!

    Awesome system for the price!!
    I bought this for my sons Malibu, I wasn’t looking for anything too powerful but something with more bass. I ordered this package , it arrived quickly the purchase was super easy. I installed this system last night, I set the gain to half way and turned on some music. To my surprise this system absolutely pounds! I was not expecting it at all for 250 watts! I turned the gain down to a quarter and that’s strong enough for what i was lookin...
