    Little footprint, big sound. Pushing a couple of old school Infinity subs. Great budget amp, lots of power compared to big names.

    Thank you Down4Sound Shop and Sundown Audio for your great customer service and products! I've installed my Sundown Audio SFB 1000D paired with a single Sundown Audio SA 12 Classic, and I have to tell you I'm impressed! I love the bass they give my truck!

    Sundown has great products and D4S has great customer service. The amp is super small it'll fit nearly anywhere. It puts out more power than my jl500/1 and is less than half the weight. Awesome product.
