AudioControl LC7i Black 6-Channel Line Output Converter with Bass Restoration

It made my factory head unit sound crystal clear.

Yup. Best stock radio upgrade ever. Have this on an audi A4 B5 and it makes the sound system come into its own. Sounds acceptable finally and honestly better than most radios I have heard. I have this paired with the MB Quart NA540.6 Nautic Amplifier, 6-Channel 540-Watt . And it drives all the speakers easily. You dont need more wattage than this on your car speakers. Most cant handle more without sounding bad. Great product. Install takes a while but worth it.

Hook this into a 2007 Honda Accord and it works great! Get the 9 in 1 wire to simplify your signal hookups

Occasionally the GTO wouldn’t turn the amps on when car is started. I chose to bypass it and wire up a standard remote turn on.

I was originally looking for a way to reduce alternator noise. After reading online info, seemed the best thing to do was find a way to take my high level speaker inputs that were run directly into the high level amp inputs from oe system and make them low level inputs for lower distortion. This unit not only turned my 4 channel speaker outputs into 6 channels. it combined it all into full range for the ft and rear and low for sub channel. It has adjustable bass levels and ... no alt whine. Id give it 5 stars but Im picky and it would be much nicer to have a separate max light for all 3 outputs, not just 1. Takes a little fiddling to get it right. but all and all very nice addition to the system. very happy.

awesome product. defiantly and upgrade to any sound system.

Wanted to keep the original look of the two deck system on my 99 Mustang with a Mach 420 system. Had to keep the original amp hooked up because the stereo outputs are only data, so it has to run through the amp before it is covered to sound. That was the only downside to the product. Other than that, it did exactly what I wanted to. I was able to put in new speakers, amps, and a sub.

Good choice for not replacement of head unit

Best I ever bought works well I recommended 100%

When I opened the package, the device was taken out of its packaging as you can see in the photo. The device clearly shows signs of use and has a deep scratch on one side. I don’t understand why the product was advertised as new when I was sold a used device. The device also came with a bass control knob which was delivered before this device why initially gave me a red flag. Very unhappy about this one. What bothers me the most is the deep scratch on the side. I wish I could post more pictures
