    Amazing little product here. If you’re looking to add some lows to your factory system in your newer vehicle, use this. It’s super simple to install and you get great clarity.

    This little thing worked great! Tapped right into the existing speaker wires (only need to tap one side since my amp is mono). Tbe remote wire is fantastic since I didnt have to mess with the fuse box.

    I had a full kicker set up; 4 speakers, amps, dual 12in sub and wiring. Everytine volume went above 18 on a 2024 model vehicle, the amp would lose power. After all the diagnostics, the only thing that needed to be done was the LOC had to be grouned!!!

    Works incredibly well and the quality is sound! (No pun intended). Upgraded from a crappy $15 converter on Amazon, the one that comes with the knob, and this enriched the sound so much more. Great purchase!

    Awesome device! Was a bit confused on installing but with some research figured it out. Installed in 2015 Silverado “B” pillar and hooked up to sub. Worked perfectly, didn’t even have to remove radio from dash!
