Great amplifier, good price!

Great selection of brands and products in all price ranges. Received my order quick. Audio Control LC800 can hardly wait to see how it sounds on my B2 12" sub.

Nice unit

This sounds real good, still tuning on it and i also have the AC 4 channel unit as well. Seems over priced but it does sound verry good!

The perfect companion for my D-6.1200. AudioControl does not disappoint. Both sound and build quality are top-notch. This amp stays cool to the touch while driving 10" Kicker L7T at 4 ohms.

I don't know what that other guy is talking about

This amplifier takes four gauges easily and it sounds great

Very solid amp but a couple of quirks...

The amp does a good job of driving a JLAudio 12W6 in my SUV. I have the amp stashed under the rear cargo deck next to the spare tire and it has never overheated/shut down.
The 2 negatives that I have with this amp is that the GTO circuit did not work for me and I had to run a separate 12v turn-on lead.
Also, the Accu-bass feature would kick in at weird random times and sounded horrible so I called Audiocontrol and they told me how to basically shut that feature off. It sounds much more natural now. Overall I am happy with the amp going on my 4th year with this install. I must admit that I am not a kid anymore so no continuous loud operation or unbearable rap is being played every time I'm in the car. But I still enjoy extremely dynamic bass that's clean and tight (sealed enclosures for me). Enjoy!

Great features!

Amp was easy to fit where I needed it to go. Hooked up to a stock Shaker 500 system via the rear speaker wires. Easily tuned and more than enough power for a JL Stealthbox

It's interesting that the manual recommends 4 gauge or larger power and ground wires when the terminal block will only accept 12 gauge- or if you really fight it, maybe 10 gauge. WTH?!

The remote turn on terminal is the same size!!!

I ran 1/0 to go to this amp (before it arrived) and now I'm stuck with no way to connect it. Ridiculous!!!

First and last time with Audiocontrol .
