SIGNAL RESTORATION

In the pursuit to get the best sound possible from your stereo system that features both factory and aftermarket gear, KEYLOC’s patent-pending KEY™ algorithm automatically detects and analyzes crossovers, EQ, time delay, and all-pass filters present, and then it will level-match the left and right audio channels. Once analyzed, it corrects these various filters to give you the smoothest frequency response possible, giving you a clean, uncolored audio signal for your aftermarket gear.

HEAR IT YOURSELF

To hear what you’ve done, cycle the EQ correction on and off with a single push of the KEYLOC’s “KEY” button – hear the before and after! Additionally, if KEYLOC detects any all-pass filters or factory time delay, you can choose to defeat the correction (from the menu) and keep the imaging of the factory source unit. By keeping the correction filter active, KEYLOC will counteract either of these factory effects so you can use an external audio processor to dial in a one-seat tune for the ultimate sound experience.

FIND THE FREQUENCY

News flash! Factory audio systems don’t always deliver full-range signal on every speaker wire. This makes it tough to hook up an aftermarket amp and get the sound you wanted – until now.

  • Asked help to power up my Kicker KS 6x9 speakers in my truck and of their guys recommended me this little amp. I had some doubts due its small size but after the first time I listened to it, wow, its was way better than before. Its DSP feature also is really great made the sound quality improved more.

  • Never underestimate this small amp. It pushes great power to my 6.5-inch speakers, and they sound very well. Its built-in DSP improved my sound system's quality very much.

  • Using it on my F150 for 2 months now. Really good amplifier. Has some power and can push the stock speakers. Its built-in DSP is what makes it better above the rest. Gave me an easy time tuning everything.

  • As a birthday gift for myself, I bought an amp to power my front and rears with additional feats like DSP and I found it in the website. Really happy after I got installed in my F150. Sound quality is excellent, power is okay, but the DSP really makes it so much better as it enables tuning much easier with it.
