AudioControl EPICFOUR EPIC Series 4-Channel Car Amplifier – 800W Max RMS

The AudioControl EPICFOUR is a high-efficiency, ultra-compact Class-D 4-channel amplifier engineered to completely transform your vehicle's full-range soundstage. Designed for audio enthusiasts who demand competition-level volume and pristine vocal clarity without sacrificing their vehicle's cabin space, this thermally efficient powerhouse delivers serious multi-channel output. Capable of pushing an incredibly clean 100 Watts RMS per channel at 4-Ohms, the EPICFOUR truly shines when dropped to a 2-Ohm load, delivering a massive 200 Watts RMS across all four channels. This makes it the ultimate building block for powering heavy-duty custom door panels packed with pro-audio midrange speakers and high-frequency tweeters.

If you require even more extreme power for massive mid-bass drivers or a pair of subwoofers, the EPICFOUR can be bridged into a 2-channel configuration to unleash a blistering 400 Watts RMS x 2 at 4-Ohms. To ensure absolute surgical control over your frequencies, it features fully variable 12dB/octave Linkwitz-Riley High-Pass Filters, allowing you to perfectly tune your speakers to eliminate distortion-causing low frequencies. Complete with direct-wire heavy-gauge hex terminals, an ultra-efficient idle draw, and a Smart Auto-Reset Protection Circuit, the EPICFOUR brings unmatched clarity, brute force, and reliability to your custom sound system—all from a footprint that is less than 9.5 inches long.

what a difference !
Note: there are no English instructions. I wanted this cleaning agent to disperse throughout the nooks and crannies of the engine, so about ten minutes before arriving at the mechanic's shop for my oil change appointment, I pulled the car over and poured this into the engine, then drove it the rest of the way there. The mechanic reported lots of sludge drained out with the oil. The engine seems to perform and sound better, as if it's not working as hard.

Buen producto
Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.

Great will use it over and over again
I will use this in every car I own from now. Cleaned it real well did exactly what it said so and my truck runs a lot better definitely can tell the difference.. it was work the extra oil and work. The bottle I bought came with instructions in English, which made it easy for me. The quality of it is light brake cleaner, but meant for engines and it ran great very easy to use this pour in.

Does its job.
Always a go to before oil changes. Helps remove some extra sludge/deposits. DO NOT DRIVE OR REV THE VEHICLE WHEN USNG THE PRODUCT, only idle for 10-15 min. Ive seen reviews where people drove with it potentially ruining the engine.
