Guys im planning on upgrading (changing) the amp i use for my seps (Focal 165 K2P), im currently using an old model Kicker ZX460 (120 X 2 RMS). What would give me better SOUND QUALITY, and be a better match for the Focal K2 Power, a Rockford - Power T8002 or a STEG - QM 120.2x ? If i upgrade, will there be a noticeable, audible difference in my system (GAGANDA BA TUNOG) even if im just changing brands and not necessarily getting a higher watt amp? By the way, another concern of mine is compatibility with my HU which is a Pioneer 8650 (6.5 volts). If you have other suggestions or reccomendations pls do tell, Thanks!
