  • Love it.
I am a nerd, so I love this lc8i. It's pretty flawless. One critique, if they could put the sum switches on the outside of the unit instead of having to take the cover off then it would be perfect.

  • Exceeded expectations
This thing is a game changer for factory integration. I was worried about integrating into a fiber optic system but the LC8i allowed seamless functionality. It was also nice to be able to keep the factory 3 way setup plus sub to utilize all 8 channels. The GTO is also great so it powers on aftermarket amps. ... show more

  • Skip the middle man..
Brand new out the box, didnt work. Receives signal but doesn't output sound. Tested it multiple times to make sure even had audio shops try to hook it up. Nothing worked. Messaged the seller and never heard anything back. Save your time the headache and order directly from Audiocontrol. Listen to the bad comments...you could be next. ... show more

  • Very good if you want clean single with control
It's a very good choice if your going to. Want the most control over your sound system. Lots of options to make it work

  • Amazing product
Amazing. I will never install with out using an line output converter from audio control. Makes my system sound great and doesn't require my amp to be turned up much.

  • High end Line out converters.
LCi's are the only way one should go, if the factory unit cannot be replaced with an aftermarket unit.

  • Performed as expected and reliably
I built a system before a 3000 mile road trip. I pushed my system 15hrs a day and it never skipped a beat. My installer only recommended this product and as expected, the install was simple and easy to dial in.
