Denali replacement alternator...

I'm sure it's on here prior, but I want your input. A couple weeks ago my lights (at a stop) started pulsating as well as my head unit and interior lights. So I bought a new battery, replaced all my grounding and main power supply (big 3) to 0awg and still I'm having voltage drops and rough idling. My next thought is an upgraded alternator. What do you all recommend for a 6.2L replacement? I'm getting nervous I am going to mess up my head unit (alpine 009-gm). I need yalls help!

I'm looking at getting a Singer alternator. Been doing research and picked that brand over mechman, GP, DC, etc.
