The Skar Audio SDR-18 D2 was designed to offer the ultra low end bass frequency response only capable of being produced by a larger subwoofer of this size. Featuring a conservative rating of 1,200 watts max power, this 18-inch car subwoofer does just that, thanks to its high temperature 2.5-inch copper voice coil and high flux ferrite motor. The engineering considerations that went into developing this 18-inch subwoofer are extensive, and contribute to why the SDR series has continued to be one of the most popular subwoofer lines we have ever released.
When looking for a subwoofer that delivers low end frequencies with authority, look no further. This is the perfect solution for a 600-1,200 watt daily driver that can handle whatever is thrown at it, offering unmatched reliability and sound quality. Featuring a sleek and attractive red spider system, paired with its competition grade paper cone and high roll foam surround, this subwoofer is going to impress the listener every time it is playing.
