(background info: I suck at car audio knowledge) I'm looking into upgrading my car stereo with some parts I have from a previous setup. Here's what I have that I want to use over: 2 10in Bostwick HD subs Sony XM 754HX Amp Now I have 2 questions. 1) Can I hook up those subs, plus the Focal 165K2 system up to the amp and obtain good sound quality out of it? 2) Eventually I will replace the head unit, just not now, and in order to keep the original I've been told I need an amp or eq that can tolerate balanced input signals. I have no clue if the one I have does and was wondering if anyone knew or could tell by some pics of it. Please go easy on me if I said something stupid, like I said above, I really don't know anything about car audio, and I want to research some stuff before I start shopping.
