About: Open Box - Skar Audio SDR-8 8" 350 Watts RMS Car Subwoofer (Final Sale Item)

Condition: The subwoofer has been previously used and drilled in. It is in perfect working condition and comes with its original manufacturer packaging.

The Skar Audio SDR-8 was designed to deliver hard hitting, low frequencies, while being ultra responsive and musical. Featuring a high flux ferrite motor, this versatile 8-inch woofer is conservatively rated at 700 watts max power. Don't let the size fool you, the SDR-8 is capable of reproducing low end frequencies with authority.

The SDR-8 is the perfect solution for a 350-700 watt daily driver, featuring a 2-inch, high temperature copper voice coil that is attached to a sleek and attractive red spider system. The high roll foam surround and competition grade paper cone found on the SDR-8, allows the woofer to produce riveting low end bass response, that will impress the listener every time it is playing.
