The XS Power SB1000-75 is a 12V SuperBank ultracapacitor delivering 1,000 farads of instantaneous energy buffering for car audio systems that have outgrown what a battery alone can provide. Its power cap technology charges from your vehicle electrical system in seconds and discharges with the speed physics demands when your amplifiers swing hard.
A Thousand Farads of Voltage Stability
Running a system powerful enough to cause headlight dimming or audible dynamic compression from voltage sag? The SB1000-75 acts as a high current capacitor reservoir between your charging system and your amplifiers, smoothing transient loads and keeping voltage stable through every hit. This SPL capacitor bank is the kind of upgrade that makes a measurable difference in system performance — cleaner transients, tighter bass, and a voltage stabilizer that never slows down.
