    • Everything you could want in a subwoofer.
When I bought this sub I wanted the most bass for the little bit of space I had and this sundown audio U series 12 D2 did not let me down. This sub is loud low and the sound quality is out of this world. People that ride in my car think that I have a pair of 12s until I open the drunk, very solid subwoofer. ... show more

    • You won't regret your purchase
These subs are tough, designed to handle the power, I've had mine for about 7 months and still am impressed with the performance. Running 2 in a gatley 4 cf Russian birch box and couldn't be happier
