Overview

If your car's audio system sounds flat in the low end — whether you're running a factory head unit, a modest aftermarket setup, or an amp that lacks onboard bass shaping — the Gravity GR-BASS2.0 fills that gap directly. It slots between your source and amplifier to restore and shape low-frequency response with a dedicated bass equalization circuit and a subsonic filter that keeps the output clean. The target user is someone who has already invested in a subwoofer and amplifier but wants more control over the bass character than a simple gain knob provides.

The build centers on a wired dash-mount remote with illuminated knobs, making real-time adjustments practical while driving. On paper, the specs are genuinely solid for this price tier: a 0.003% THD rating and -130 dB signal-to-noise ratio indicate the processor won't introduce audible coloration or noise floor issues. The Bass Maximizer indicator adds a useful visual cue to keep you from pushing the equalization into distortion territory. It's not a Swiss Army knife — it won't replace a full active crossover — but as a focused bass management tool, it delivers measurable, listenable results.

Pros & Cons

👍 Pros

  • 13.5V RMS output level gives clean headroom for most amplifier inputs without signal degradation.
  • The -130 dB signal-to-noise ratio keeps your audio floor extremely quiet, so bass boost doesn't introduce hiss.
  • 0.003% THD rating means the processor adds virtually no audible distortion to the signal.
  • Subsonic filter prevents subwoofer damage and port noise from ultra-low frequencies your system can't handle.
  • Illuminated knobs and logo make in-dash adjustments accessible in low-light conditions.

👎 Cons

  • The wired remote is a physical install — running the cable neatly through the dash adds setup time compared to wireless options.
  • Bass Equalization circuit offers general tuning rather than a parametric or multi-band EQ, limiting precision for complex system calibration.
  • Pre-formatted output is fixed at 150 ohms impedance, which may not be optimal for every amplifier input stage.
  • No built-in crossover — you'll still need a dedicated crossover or amp with one for a full active system.

Frequently Asked Questions

Yes — it's designed to integrate with most factory and aftermarket head units. It sits in the signal chain between your head unit and amplifier, so no special head unit features are required.
The PFM subsonic filter cuts frequencies below the range your subwoofer can cleanly reproduce — typically below 20Hz. This prevents your sub from wasting power on inaudible content and reduces distortion and port noise on ported enclosures.
It's a straightforward wired remote that mounts in a standard single-DIN or bracket location on your dash. The illuminated knobs make it easy to adjust on the fly without taking your eyes off the road for long.
The Bass Maximizer indicator lights up to show when the processor is actively boosting low-frequency content. It helps you avoid over-boosting, which can push your amplifier into clipping.
Yes, it requires a 12V connection from your vehicle's electrical system — standard for any inline audio processor.
