I have an older alpine F450 amp bridged running a pair of Hertz components and it's overheating after about 45min-1hr of playing loud. I already had this issue with this amp running those same front with a 10" sub so I bought a dedicated sub amp.
The amp only runs the fronts now but again it will eventually get too hot and cut out for a few seconds if its running hard for too long just like before.
I want to move away from a 4-channel amp to a 2-channel amp so here are my questions:
1. What are some good recommendations for an amp like I described to run only front components? I would like to run the full RMS to the speakers like I'm currently doing.
2. Do mids-tweets sound better when running at 4ohms vs. 2ohms or does that have no effect on sound quality?
3. My sub amp is a digital D class amp and stays cools and doesn't beat on my electrical as hard as this older AB alpine amp, are AB amps still the way to get the most sound quality out of mids-tweets or are these new digital D class amps have just as much quality of sound as AB amps?
