Power your car audio system from a standard AC wall outlet—without running your vehicle.
The Massive Audio HPS100 converts 110–130V AC household power into adjustable 1–16V DC power, delivering over 100 amps of DC current to power car audio amplifiers and other 12V equipment outside of a vehicle's normal electrical system.
Perfect for showroom displays, demo boards, car shows, test benches, and other stationary car audio installations, the HPS100 provides regulated DC power without relying on your vehicle's alternator or draining its battery.
Need more current? The HPS100 is linkable, allowing multiple units to work together to supply over 400 amps of DC current for larger, high-power systems.
Built for demanding applications, the HPS100 features an adjustable regulated voltage output up to 16V, triple internal cooling fans, a remote-mount LCD voltage display, and automatic overload protection.
AC power in. Car audio power out.
