Well, I obviously don't wanna go overboard, because the stereo is pretty basic, but I want something that has good clean sound. Can a quality 4 channel amp be had for around $3-400 dollars? I only have 1 10in sub, and surround speakers, because all I wanted was some nice full range sound, not huge bass or to overdo it stereo wise. I saw an Eclipse EA4000, is that amp any good? I see many different amps from the above manafacturers, are there things that I need to look out for when making my selection? Thanks again guys. I appreciate the input/suggestions.
