Well explained 😊 keep it up!😊😊

The bass voltage output, actually sends out a stronger signal based on where you place those jumpers. As an example, If your head unit only puts 3 volts but you set up your Epicenter jumpers to 7.5 volts, its going to put that pre output voltage. Epicenter is not a line output driver but it does create synthetic bass of its own, in coordination to the harmonics is receiving from your music, so the jumpers are directly impacting your bass pre output voltage, not "limiting" like some people here are suggesting. You just have to make sure your amp supports the pre output you are sending it... you dont have to have a 20k watt systems like you suggested as I have a 600 watt kicker bass amp that supports up to 40v of signal input, so as long as you match your amp correctly, you will do no harm to your equipment by putting a higher voltage on the Epicenter. Just the opposite, you can benefit from having a stronger signal by setting gain knobs lower, lower signal noise and more pronounced & impactful bass!

The way i understand the bass output jumpers is. They limit the voltage going to your amp. Meaning.  If you have a 5 volt output head unit but your amp has a 2 volt imput. Putting the jumper to 2.5 will limit the signal voltage to 2.5. The epicenter is not a line driver. It doesn't increase signal voltage. It can just limit it. That's what i understand from what I've read. Kicker has a pretty good writeup on it.

I’ve had my epicenter since 2006 and it’s still currently pushing my system nice. I’ve switched out my PFM module from the original 33hz to 20hz module. Nice job on this video.

How do the unbalanced jumpers work for the left n right?

Not fully explained.  You missed the Balance jumpers

Omg I have to find my gray one 😳😢

Yo tengo mi cajon entonado a 38 hertz entonces tengo q comprar otro chip q tenga 38 también??o puede usar el q viene d fabrica d 33 hertz??

Nothing wrong with the Planet audio, Soundstream or Power Acoustik Bass restorators. The only quality difference I can see is Audio Control knob is better build, with a metal enclosure. If you wanna spend extra for that, go ahead.  but some of those mentioned brands have better features like variable subsonic filtering right their on the remote knob.  I own & love A.C. Epicenters. But it's a 1 trick pony that hasn't innovated much to stay ahead of the competition.  They only have brand loyalist like the guy in this video. I have an original P.G. Bass cube, and it's more suitable for todays 808 heavy trap beats. You try to run 808 heavy trap threw an epicenter, and it will make it sound worst in most cases.

I don't understand in the manual. Does the light blink on the unit to show that the output is maximized? Or is just for visuals?

Hard to hear the video..

🔴 I STILL GOT MINE FOR 17 YEARS STRONGER WITH A CERWIN VEGA SUBS AND KENWOOD DECK. PETE THE BUILDER

4:30  If there is no explanation as to how some things are not quality built, then it is merely conjecture.  
The testament of being alive 20 years later is not afforded to those who did not hold the patent, because they couldn't legally produce the same equipment back then.
My Blaupunkt EP1200x works perfectly fine and I can't find any explanation why to spend $100 more for the same function.
