    Sounds great

    Feb 24, 2022

    Ordered two of these that came pre installed in a sub box for a 2018 Ford f150 supercrew. One was not functioning when it arrived but the customer service was great and I had a replacement within a few days. They sound really good and I am very satisfied with the speakers
