Hello car audiophiles, this is my first ever forum thread anywhere. I'm just wandering if I need to upgrade my alternator to a "high output", and if so, what amperage would I need. My setup currently is a 02 Buick LeSabre, with a 800cca battery from advance Auto, with a PSI platform 3 12 inch sub, dvc 2 ohm that pushes 3000w. The amp I'm trying to use is a soundstream 8000w.1d. the amp pushes 4000w rms at 1 ohm. I tried using my current wiring setup(4 guage and all stock electrical wiring) and when I did the amp kept blinking into protect mode and making a very loud distinct whine through the speakers. When I felt the amp, it was as hot as a firecracker, and so was the 4 guage power wire. Please help someone
