Why customers choose Nexoltic

Compact power, big bass

The JBL BassPro SL delivers deep, controlled bass from a compact 8-inch driver that fits neatly under most seats. Its integrated Class D amplifier keeps the footprint small while delivering punchy low-end response, so you can enjoy your music without sacrificing cabin space.

Designed for easy setup, this system uses high level inputs with Audio Sense Auto-on, allowing straightforward connections to factory radios or aftermarket head units. A soft start turn-on reduces startup noise and electrical stress, contributing to a smoother listening experience from the moment you power up.

  • 8-inch powered under-seat subwoofer enclosure with integrated amplifier
  • Peak power up to 250 watts; RMS rating around 125 watts
  • Efficient Class D amplifier for strong yet clean bass
  • Soft start turn-on and Audio Sense Auto-on for smooth activation
