What is 'substage' anyway ? You mean your subwoofer system. Soundstage is used in the wrong way sooo much nowadays. A 'soundstage' is the entire system sound. You want the soundstage to be front and center, with the lowbass seeming to come from dash center and under the headunit, and the mids above that, and the highs above the dash but below the rearviewmirror. Correct soundstage will have all the sound seeming to come from around the area of the headunit.
Please don't take me for rude, but I know a few things about audio. I am going to try something that I personally think will work - but we'll see how bad the staging is.
Sub stage is just that - low end, par se 60hz and under, roughly.
Single 18" subwoofer and a little bit of power. And trust me, I cannot afford a component set to take the power to keep up.
