    Cheap, strong, powerful, well built. This product pairs well with the thin loaded CompC enclosure @ 2 ohms. More than satisfied with my purchase.

    For only being a small wattage amp, not only have i gotten to see this be used in many vehicles, it perfectly works with Kickers Comp C subwoofer line up. Ive had zero issues. Set the gain low to let the system warm up and after the break in i turned it up and it works as i wanted! Couldnt be happier

    Just got it today, can't speak to the longevity of it, but it makes my car bump without making me "that guy" at a stop light. Definitely happy with the purchase. Which was open box at $121. Super happy.

    Works great with my ds18 gen x 12" subwoofer. Installed with an lcp2 pro inside my 2022 veloster N havent had any issues with the set up. If you want to do wire attachments for solid connection points you will need mulitple different styles and id say thats about the only downside
