I understand your logic David but unfortunately the ep4000 doesn't offer that s-converter is a guy thing to have too...
You're right, there's a lot of pro-amp (including ep4000) that will require the converter to work the way is supposed to work, I was just saying that if others want to avoid using more equipment/connections just to look for pro-amps or external amps with RCA connectors.

After reading your post I was wondering why I didn't use the S converter when I connected my SonoSub, then I realized that my amp (BKA 1000) has RCA's.....

Currently i think 2 separate?...I was think about making a new box maybe tuned lower towards 35 32ish with dual 6 in ports (flares) in about 4-5 cubic feet also i would like this box to easily be modified to fi the 18 if possible or a box that could keep all 3 and when i rid of the kickers just board it and seal...The box i have is good and durable but the binding plates are garbage and the box it small.

Any ideas?

Oh sorry no i dont have the q yet I have Kickers, but id like the box to be for music and HT.

And for the box to be easily modified to fit the Kickers and the Fi Q when I get it.

Sorry for the confusion guys
