Hello guys,

I have a S8 Premium and i cant get the subwoofer to work.

So my connections are:

From the Atoto subwoofer output to the amplifier and from the amplifier to the subwoofer. A complete normal connection between radio and subwoofer.

When i connect the subwoofer to the RR/RL or FR/FL it works like a normal speaker but when i connect it to the subwoofer output like it shud be it doenst work.

I made a video trying to find the subwoofer settings and i cant find it, i have seen alot of videos where you can turn on/off the subwoofer, but in my atoto i dont have that functionality.

Can anyone help? Thanks guys!

Did you ever get this figured out? I found the sub settings but the output is very low even turned all the way up in the eq app.

Nice, I just ordered this one to boost up my sub output:

But I really like that 3 way one idea too hmmmm.....

The Subwoofer rca output in the manual indicates it at .5 volt. Most mid model head units deliver 3-5 volt output as you may already know. The best solution is to purchase a D.S.P or a crossover, etc. Line drivers usually have alot more than 1% THD. Most name brand types of car audio have become real affordable. I use a Rockford Fosgate 3.sixty.3 that allows voltage adjustment from 2-8 volts of output. Also make sure you use a good quality rca cable that is insulated and is OFC. I use Stinger 8000 or 9000 rca cables and Sky High triple sheilded makes a good set . They make a drastic difference . I had to buy a Y rca splitter as the sub output only has one out.

I have the same issue. I have an S8 Standard in dash. I cannot get any "Subwoofer" output from the unit. IF I connect any 2 channels from the unit to the subs amp. It works only after I have adjusted the Bass settings in the eq. But I don't have control over the Sub sounds really. However, But if I connect the single RCA "Sub Out" from the back of the Atoto S8 unit. I get absolutely no output. So I got a T splicer and connected the single Sub Out to Both RCA inputs on the amp. Still nothing. I know its only .2v output from the head. The amps input sensitivity is .250v-6v. Its a Nakamichi NKMD60.4 4 Channel amp, Bridgeable. 1500watts max. Connected to a Polk Audio DB+ 8 Inch 750 Watt 4 Ohm DVC.
But I should hear something. The gain on the amp is maxxed out. And My amp requires two channel inputs. But the head only has 1 RCA "Sub Out". So what am I missing? Is the power from the HU not enough? Or do I need a Line Booster? Or am I missing another step I don't know about. I checked the HU Sub Settings and the frequencies are within range. But still no output from that Sub jack on the back. I have a PAC LD-10 Ground Loop Isolator Adjustable Line Driver Signal Booster+10X Preamp on order. Should be here Tuesday. Im hoping this will solve the problem. Any Ideas?
