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

I used the LC7i to sum factory amplifier output channels to get a full range signal for my amplifiers (1 monoblock amplifier for subwoofer & 2 channel full range for front stage speaker upgrades). The cover was easy to remove to switch the jumpers to sum so that all inputs are combined to one full range output. The signal it puts out to my amps is high voltage and super clean (no noise even parked in my Lexus with windows up - super quiet vehicle so would be easy to hear any noise introduced into the audio). The accubass features works well to counter factory bass rolloff at higher volumes. Construction and fit/finish is very good - this product is well made and built like a tank, and its always nice to support products actually made (from start to finish) in the USA! :) The only downside, and the reason 1 star is missing: Audio Control will not warranty unless sold through an authorized dealer, and then only for 1 year UNLESS the authorized dealer installs it, then the warranty is 5 years. This is inconsiderate of the many of us in the DIY mobile audio who are competent and have years of installation experience, but are not ourselves authorized dealers for Audio Control. The authorized dealers also try to sell this at full retail price and the ones I spoke with locally were only will to discount on price IF I paid them to install (which costs extra) - not cool since installing this myself, with my knowledge and background, is a piece of cake. I believe Audio Control should re-evaluate their policy on this - most people with no car audio installation experience and no clue about car electrical systems would be way to afraid to try to install this, so its mostly a non-issue. Those of us confident it is something we can do in our sleep shouldnt be penalized on warranty. If damage to the unit was caused by improper installation, Audio Control would be able to see the evidence and could simply have a clause in the warranty that user error is not warranted...

the best thing you can buy to keep original your dashboard and still getting a good sound

Only one side was functional

It made my factory head unit sound crystal clear.

It works great...a little hard to install and the owners manual wasnt easy to read but overall it has performed great...the accubass seems to miss some frequencies and over due others but just turn that part off and its great!

This unit made a huge difference in my audio experience! Crystal clear with no white noise because you have to ground electronics properly - period. I was able to max out my gains on the amp and the unit with zero distortion or noise. Take the time to read up on how to properly tune these devices and you will be more than happy! I highly recommend the base knob as well if you are installing a sub, it is worth the extra $.

I am going to remove the product after several attempts to figure out why the speakers are so bright. I tried there tech support they were quick to anser questions but im ready to start over

I had fun working with the lc7i. I used to have cheap line out converters running to my amps (front door speakers, dash tweeters, and subwoofer). The difference is huge. There is a clearer, more vibrant sound stage than I had before. Since the lc7i is active (needs 12v power supply), you get a cleaner, more powerful signal than with a cheaper line out converter. I ended up having to turn the gain to minimum on my amps because of the great signal this puts out. No clipping or noise in my case. The bass boost actually works and subwoofer sounds bigger than it used to, without overloading. I trunk mounted mine with all my other audio stuff. Summed the signals for a cleaner output. There are better more expensive options with equalizer options. For the price this product is awesome.

I wanted to install my Kicker L7 sub and amplifier to my stock Lexus is250. This was exactly what I needed and it made the installation a breeze. I love the sub specific adjustments on the unit which allowed me to adjust the sound to my own preference.

Best I ever bought works well I recommended 100%
