    Sundown audio u series 15 In 1500wrms

    Posted by Chris on Apr 17th 2020

    By far the best sub I’ve ever bought. The build quality is perfection and some and the ass is fat and heavy! :) The price is well worth it. I’ve paid the same price for subs half this quality in the past but never again. I’ll be ordering another very soon to have a pair of these badass subs.

    Grate sub sound is crisp and clear low are good and will get better with time love me some lows. She's handling the v12 mrv 1507 nicely had a 15inches treo and I feel as this sub is much clearer. Only a week old and I'm in love will definitely think downfor sounds befor my next audio purchase

    Beefy woofer

    Posted by Scott Weaver on Mar 17th 2019

    Just put in my Kia Sportage last night and it is very punchy and upper bass tones are clear. Low end extension is great but I know over the next month that will even improve. At this moment I am only running 605w RMS according to my AMM-1 but it has much more output then the DC level 2 12” that was in the car before with the same power. The only issue I have is the sundown logo is not level with the mounting holes so I had to turn the woofer a little.

    Sundown u 15

    Posted by charles trudeau aka aaron jones on Nov 29th 2018

    Amazing subwoofer hits hard. Lows not too hard but it's incredibly clear and precise. I'd imagine if you got a custom box for it it will perform alot better. All in all an amazing subwoofer you can play hard all day and not worry about heat. But if you crank up the gain and over power the hell out of it it's on your head. I drove from Ri to Maine playin this sub the whole time and it never got too hot. Stays cool. If ya want super powered lows get a x or a team or a nightshade series if you want a great sub for a daily driver. Get this.
