Review on Enhance Your Car Audio System with Gravity GR-DBE Two Channel Line-Output 🚘 Converter: Digital Bass Enhancer, Dual Amplifier Support, Pre-Amp Outs, and Level Matching Controls by Joshua Fuoco

I researched enough about line out converters and came across this one. This Gravity DBE unit sounds great, but my factory OEM mini subwoofer produces higher bass frequencies down to 250Hz. Non-original MTX subwoofers operate down to 250Hz in a sealed enclosure and sound great. This device cuts off all signals above 100 Hz, so I noticed stringy bass, some instruments suddenly disappeared from the tracks after installation. A crossover control that lets the signal pass through to 250Hz would be ideal, but that's a huge musical loss, as this is a noticeable loss of that frequency range. You may need to use the KISLOC 2 kicker (the one without the remote cable) as it operates from 20kHz to 20Hz as my bass amp has its own crossover.
