Easy to follow instructions made the install a snap. It handles the high power of my stock system and the optimized/ clipping light made tuning a breeze

Install line driver to provide higher sound quality to sub amp..no clip ...sub sounds amazing Audio control is best at what they do no one comes close !!

This is essential to adding subwoofers to your stock unit in vehicle. It is universal meaning that it works with all stock radios in any vehicle with the least amount of money.

I went from a Metra LOC and this thing makes one heck of a difference, I can play my subs louder for longer since this thing has a light on it to tell you if your signal is clipping, the instructions were super clear, and I loved not having to run a separate line for remote on, my old LOC used to play this bouncing bass note when I turned the car off and back on, and would pop when I turned it off, this has a feature that stops that from happening and it has been so nice. If you're experiencing a loud noise trying to play your subs, and you're using a factory touch screen radio, go into your settings (some have a special menu like my 17 Maxima did), and turn off ASC and ANC, noise cancelling can cause that and then ASC is a simulated sound of the engine for if you're going fast and a lot of cars have it.

Great for strictly STOCK headunits (wanting to add an amp/sub to a stock aka factory headunit). The procuct runs well, is compact enough to not get in the way or tuck somewhere (if you can run wires properly). I would definitely reccomend the lci 2 more so though because its more "future proof" incase you want to upgrade your system in the future. With this one your limited to one set of rcas which means... ull have to use a splitter if worst comes to worst and you wanna add another set of rcas... dont do that! Go with the lci 2 unless your ballin on a budget and have no other choice but this one... But for the price its the best lci 1 on the market... performance is great, looks nice and clean, and is very easily adjusted. 4.7 outta 10

I give this item a A+ Quality Functionality UserFriendly Reasonable price Exactly what my sound system needed , not only did it boost my sound it cleared distortion with its effect as intended

Works great for the application. Currently installed in a Tesla Model 3 running a taramps 3k on 2 12s. That in itself makes it worth the purchase. Senses input and will automatically turn off and on the amp which makes ease of access even better. Highly recommend for stock applications when adding subwoofers.

Very good product good connection and very good controls

Simple to install. Keeps the original radio in my truck so I didn't lose any of the infotainment features. The option to use this as a remote turn on is amazing as I didn't need to run the extra wire in an already congested space.

Great device small and compact. Sound is nice and clear

Was everything i needed and worked awesome. Sounds great

Audio control is too notch. Don’t settle for an Amazon knockoff or some cheap company if you want clear accurate sound in your car audio system

Wow makes my sound system sound incredible. Im amazed by the sound and great quality.

This work good with my taramps 2.6 pro DPS. I love the soft turned off and the soft turned on. sound quality perfect

Another high quality AC product. Really helped me optimize my system in my 2014 Mercedes E350. Highly recommend if you are keeping the factory head-unit/navigation system.

Good would buy again if I had too pushed hard sounds good

Honestly great, I use it to take my stock sub input and convert for my aftermarket sub, and it does wonderfully! I would absolutely recommend this

Perfect. Didn't even know that these existed... Thanks best buy for the perfect link / addition to the GLK 350 that will save my factory radio / head unit.

Installed this to replace an lc2i i already had installed which was damaged at the rca ports. Seems legit

Love this for my non after market radio works just fine
