Hi guys,
I have the match up 7 with focal speakers for front doors and rear pillars, and eton for the central HP (keep OEM subwoofers). Do you think it is necessary to connect the amp to the battery ? Should I expect a quality improvement in the sound ?
Also, I'm a not specialist for audio tuning, is there a website that explains how to use the DSP tool ? Because it sounds strange for now, voices are too loud and central speaker too.
Thanks
