    Gets Low

    Posted by Blake M on Jan 04, 2023

    I wanted a good yet budget friendly set up for my daily driver and I tell you what this is it. It POUNDS for the price point. I paired it with the pro fab single 12 box and man does it sound awesome. Worth every penny. Sundown outdid themself with this sub and amp. Buy it.

    I was looking for something with the right amount of hit for the right amount of money. Great set up. Paired it with the d4s box. Perfect set up.

    Perfect pairing

    I have this sub/amp combo and they are a perfect match for each other. I have the sub wired at 1 ohm so it's getting the full power from the amp and it seems like it could take more. Couldn't be happier!
