    Amazing setup tool. It’s almost as great as the D4S service. This tool will save you so much time. Worth every penny trust me. Unless you want to clip your amp do it right and get the DD-1.

    Extremely satisfied with my dd1 purchase from Down4Sound , it really is as easy as it seems on all the videos on YouTube, just follow the manual and you’re set . No clipping means more life to your system . Shipping was INSANE ! Basically the Down4Sound standard. Received my order in about a day and a half , from Nevada to South Fl , the D4S team is something else .
