AudioControl LC-4.800 800W RMS 4-Channel DSP Matrix Car Amplifier with AccuBASS – High-Power Full-Range & Subwoofer Performance, Low-Distortion Premium Audio Upgrade

Some have said this amplifier had problems or issues with design or build, but I'm here to dispute that claim. I now own 3 Audio Control amplifiers, and one DSP, the DM-810. Two LC 6-1200 and one LC 1-1500. I just upgraded my fronts and rears to Morel Elate Carbon Pro 63A, with two 12" Rockford Fosgate TW1's. Sony XAV-9000 ES head unit. All interconnects are Worlds Best Cable Mogami interconnects. I installed and tuned everything myself. This is a complicated amplifier, yes. It has Linkwitz-Riley crossovers for all channels, and channel summing for all channels as well. 1-2 for high, 3-4 for bandpass OR high or low pass, and 5-6 for low pass. If you do not know how to set an active crossover, do your homework. These amplifiers also have MILC detection, which tells you when each channel is maxed out, and beginning to clip. Important for anyone that wants to listen at high volume without distortion, and especially while tuning your input and output levels and gains. These amplifiers also have a 5 YEAR WARRANTY. Register your amplifier online, and they will repair or replace components inside, or replace the amplifier. They are "designed" in America, and fixed and repaired in America. Much like your Apple phone. Just better. These are priced according to the quality of the components internally, as well as the technical design. If you want to pay for Walmart quality components and design, get a Walmrt amplifier. When you're ready for a professional, high quality, high-end amplifier, get one of these. You will not be disappointed.

This amp produces very clean sound for my mid and highs. Very configurable for different applications and easy to install.

I’m only knocking this amp down one star because I do not like the screw in terminals they use. The style being able to unplug all your speakers at one time is kind of cool. But the small Phillips type screwdriver you need was a poor choice. It should at least have a hex head. I also don’t like the way they did the cover on top. That actually uses an Allen wrench they supply I don’t know why they couldn’t do that with the speaker terminals. The cover is just inconvenient to take on and off and if you’re like me installing this under a seat it a huge pain to have that cover. I actually just have left it off. The amp is also pretty much wide open on one side so if you’re concerned about dust and dirt this might not be for you. But the benefit is that it’s getting plenty of air to the circuit board. But as performance and quality it’s a good amp. The adjustments you can make work good. The clip lights work perfectly. Makes it easier to set up and use. I tested it with an oscilloscope and DMM and the lights are dead on correct. So if you want to just turn your stereo volume up to 75% and turn the gain till lights start to blink and back of a tinny bit you’ll be set. Went from 45x4 amp to this 125x4 and it’s been great so far. Running 100 watt 4 ohm speakers and it definitely improved the sound quality and overall performance. I would recommend if you’re getting it for a good deal, as in much less than retail. Again really wish they didn’t use a tiny screw head for the terminals. Also if you can put wire ferrules on your terminals do so. It definitely helps and makes it a cleaner install, easier to work with etc… See pictures, amp rack I started and size comparison to an old MTX I had been using.

Power and clean sound signal

Paired with audio control speakers, this thing is awesome! And it should be for the price!
