AudioControl LC2i

The AudioControl LC2i is a 2-channel integration processor that requires two channels of compressed audio and transforms them into a signal wired to an amplifier. It can receive signals from amplifiers with a power output of up to 400W. It equates to a 40V signal sufficient for applications such as the infamous BMW subwoofer amplifiers. The product’s output voltage can be set up to 9.5V, and its output impedance is 150 ohms. When the volume is turned up, specific factory radios decrease bass production. To mitigate this, the AudioControl LC2i model is built with a program called AccuBASS. AccuBASS can raise bass frequencies above a predetermined threshold, giving your aftermarket speakers and subwoofers more warmth and effects.

The frequency response ranges from 10 Hz to 100 kHz, with a 1 dB threshold. The signal-to-noise input is higher than 110 dB, and the amplitude is 0.01 percent. The product requires a power and ground link and less than a current that is lower than 1A to function. The AudioControl LC2i comes in a compact design, with a size of 6.5 x 3.25 x 1.5 inches. Therefore, it will not take much space in your car.


  • It can fit many types of factory audio systems
  • Has AccuBASS function to boost the bass sound
  • Compact design


  • None

AudioControl LC2i PRO

If you are willing to spend more for an upgrade, consider the AudioControl LC2i Pro version. With this product, your factory audio system will give the absolute best signal to the amplifiers. The LC2i PRO’s load selection switches make OEM integration a breeze, and it’ll even fit with the most delicate car sounds. It can be adaptable to GTO™ Signal Sense, audio sense, and 12V inputs with activation modes. The state-of-the-art AccuBASS feature also appears in this version to boost the bass sound in your vehicle. Now you can enjoy a much more fantastic listening experience on the road. The sub can also be monitored with the supplied ACR-1 level remote control. The maximal speaker level is 40V/400 W at 20 ohms. The signal-to-noise proportion is greater than 110dB. You can choose among 20 ohms, 60 ohms, 20 ohms for input impedance, and the output impedance is fixed at 150 ohms. This product’s size is 6.9 x 3 x 1 inch, a neat design to fit your car perfectly.

AudioControl LC6i

Another option you can take into consideration is the LC6i model from AudioControl. This product is an upgrade compared to the LC2i and LC2i pro versions. The LC6i enables aftermarket amplifiers to be installed while still using the factory volume and steering wheel controls. It is the best OEM interface for a performance audio device, thanks to internal signal summing and novel GTO™ signal-sense turn-on. As the name suggests, this product has six-channel stage inputs that are compatible with signals of 400W. We also found feedback from a user who said that he/she connected this to a 1500W system, and the product provided excellent voltage and crossover versatility. The sound you will hear from your car’s audio system is going to be enhanced significantly with boosted bass and extreme clarity. The difference is noticeable, and it will satisfy you. The product’s size is 11.5 x 8.19 x 2.2 inches, which is slightly bigger than the LC2i and LC2i pro models.


  • Six channel level inputs
  • Provides clean and excellent sound with boosted bass


  • None

AudioControl LC7i

If all three options could not satisfy you, AudioControl still has another upgrade for you, the AudioControl LC7i. This product is also the final one that we are going to introduce today. This product is a six-channel active line converter. It is the perfect solution for people who love music and desire a better listening experience on the road, which will retain their factory-mounted source unit and significantly boost their device efficiency at the same time. The LC7i offers incredible sound quality and compensates for one of today’s factory systems’ most significant flaws: the low bass level. It is built for optimum sound quality and improved audio efficiency. This product also has AccuBASS. As we already mentioned, this proprietary method can automatically modify the bass roll-off that is typical to many factory sound systems, and the special and exclusive AccuBASS circuitry will preserve and retain the bass when volumed up to enhance the audio output.

The LC7i enables versatility in powering downstream audio signals to single or multiple factory amps, optimizing sound quality and providing high performance. Moreover, it is made to fit into a lightweight frame that makes quick and modular factory modifications in today’s space-saving vehicles. You can purchase an additional remote ACR-1 dash to monitor the low-frequency output level.


  • Boosts bass quality significantly that can satisfy any ears
  • Compact design


  • None

That concludes today’s article. If you are into music and want the best listen-on-the-go experience, the AudioControl LC2i will be your best solution, along with a couple of other choices. Thank you for reading!
