Most factory stereos, even premium systems, protect speakers by reducing bass output when the volume is turned up. This limitation works great in a stock system, but it'll hamper low-frequency performance if you upgrade your factory stereo with amplifiers and subwoofers. MTX solves this problem with the re-Q5 signal processor.
The re-Q5 senses the input level from the factory stereo, adding more bass at high volume levels and keeping bass response balanced when the volume is low. You'll enjoy full, even bass response at all volume levels. Now you can keep your factory stereo and its steering wheel controls while truly improving your system's sound.
The re-Q hooks up to the speaker outputs of your factory stereo, and includes front, rear, and subwoofer preamp outputs for connection to your amplifiers. You'll find individual gain controls for all the outputs, plus low-pass and subsonic filters for maximizing your sub's performance. A bass enhancement switch lets you kick in a little more bump if you desire.
Another bonus the re-Q5 includes an auxiliary input, so you can tie an outboard sound source into your factory system and control its level. The auxiliary input module comes with a 16.5-foot cable so you can mount it in a convenient location.
