AudioControl LC2i PRO 2-Channel Active Line Output Converter with AccuBASS for Adding Subwoofers, Amplifiers to Factory Car Audio Receiver Head Unit, Includes ACR-1 Dash Remote Bass Knob Controller

I used this on a BMW M5 with the stock sound system and was very impressed. Installation was straightforward and easy to complete. It made a noticeable difference in correcting the frequency curve and really improved the overall sound quality. Highly recommend for anyone looking to upgrade their factory system without a complicated install.

50,000 mile review. It's perfect. Does exactly what it's supposed to do. Works well with 16v input even though it's not advertised to. Compatible with any vehicle including my 2023 Tesla model 3 performance. Very durable. Sound quality is not an issue. Expensive for the money but you know you are getting a great product.

works great for factory radios had a speaker rack installed and ordered this for my factory radio

Made connecting to factory radio a breeze. Installed in my 2017 Tesla Model S and absolutely love the output. Definitely recommend to anyone looking for n easy install.

If you're like me and have a newer vehicle with lots of factory options that run through the head unit, going aftermarket can be a huge pain in the rear. This active LOC has crystal clear sound output without all the engine noise and muddy sound processing from a budget aftermarket setup. Works even better if your car has a factory amplifier with a low frequency output. It's also fairly easy to install whether you have very little experience, or many years of car audio under your belt. There are also some very easy to follow youtube guides that explain all of the features and how to easily set them.

4 stars just cause I didn’t get the pick

Worth every pennies.

This thing is a game changer output is very good. Easy to set up sound frequency is way better than the regular LCI converter. Go with this one you will be satisfied.

Best product

Llegó sin el control a distancia, si bien decía que el producto estaba ya abierto, comentaba que contenía el mando a distancia el cuál no llego

Although these are primarily used for car audio to enable addition of amplifiers and subwoofer to a factory radio , I used this as a home receiver tool to add pre-outs to run my Center channel from a secondary amplifier. This allowed me to run 2 Center speakers together bi-wired using a channel A+B amplifier as secondary mode. To power it, I repurposed a USB Sata adapter power supply ( for external drives) and was able to run a trigger wire from the main receiver to power it on at the same time as the main receiver. I was very happy with the result. It widened the presence of the Center speakers (2) considerably and sounded awesome.

Very good product, have excellent instructions on how to connect it. I love the front knob to control bass.

Easy way to derive clean bass signal from a system with no subwoofer output. In hindsight I would have ordered the audio control mini amplifier which has this built in. It would have saved space and time during install...
