Ok Im running the PG RSD 65cs in the front and the PG RSD6.5 coaxial in the back. All powered by a Alpine MRP F550.
RMS Power @ 4 ohms: 4 x 90W RMS (4ohms, 14.4V, 0.08% THD)
With the gain set at 0 front and rear. Frequency set at 45 for the front and 65 in the rear. When I crank my headunit all the way, it sounds like its distorting a little. I know some guys pushing way more power than this. Why do mine do this? Any settings i should mess with?
