DDX-15 | 15" 1,500 Watt Max Power Car Subwoofer

Coil Configuration
  • The Skar Audio DDX-15 D2 is a competition grade, 15-inch, dual 2-ohm, car subwoofer. The DDX line-up was engineered by Skar Audio to be a SPL grade woofer that could also be utilized in daily system applications, allowing non-competitors to use the same subwoofers as those competing in the lanes. The DDX-15 is equipped with an advanced air flow cooling system to help dissipate heat, enabling it to provide continuous reliable power.

    Conservatively rated at 1,500 watts peak power and 1,000 watts RMS power, this subwoofer was engineered to be extremely loud. Featuring a massive double stack 202 oz motor, 2.5" pure copper high temperature voice coil, and a competition grade pressed paper cone, stitched to the high roll foam surround, the DDX-15 comes equipped ready to handle serious amounts of power.

Very nice subs

I Ordered 5 of these 15s for my wall build i am super impressed. With these woofers. I gained on the meter with these metering a 160.8 db. At 47hz on a single korean 7500d. Amplifier Super nice efficient loud woofers would reccomened these to anyone looking for budget daily driver Spl bangers.

Amazing

I LOVE THIS SUB!!! I got one and have been breaking it in on 600w RMS for the past 2 days, and. It absolutely slams!! My car is getting destroyed, and I’m hitting new lows I’ve never felt. Can’t wait to try some real power soon. Way way better than my old 2 Memphis 12” craps! Thanks Skar!

Performance for a price.

So far so good. Only used them for a few days then started my 1 to 1 6th order. So soon I will give another input on 8 of the ddx 15s on a crescendo bc17k.

Impressed

Ddx 15 d2 running on a rp1500 in a 4cf box tuned to 36hz. designed and built by me, painted with help from my step daughter. My pontiac vibe flexes in ways it never has. Will be upgrading my mids and highs to skar
