Hello,
I have an old school Rockford Fosgate Punch 250a2 amp that I am trying to figure out how much wattage it will supply at a 4 ohm bridged load. The amp is under rated. I am having trouble using the birth sheet to figure out how many watts it will 'really' supply. It is rated at:
(Dynamic Power Rating) - IHF-202 Standard
320 Watts X 1 into a 4ohm load at 14.4v
160 Watts X 2 into a 2ohm load at 14.4v
100 Watts X 2 into a 4ohm load at 14.4v
(Continuous Power Rating) - Competition standard - RMS continuous
62.5 Watts X 2 into a 4ohm load at 13.8v
125 Watts X 2 into a 2ohm load at 13.8v
250 Watts X 1 into a 4ohm load at 13.8v
The birth sheet states:
"Actual Total Power(All channels driven into a full power at 2ohm) 362 Watts"
It looks like this test was performed at 14.32v.
I 'think' that this translates to 362 Watts X 1 into a 4 ohm load at 14.4v. Is this correct? I want to adjust my amp's gain using a DMM. The amp won't really be getting 14.4v. Will it? What wattage should I adjust for due to the lower voltage? My sub is a JL 12W3 D2 wired for a 4ohm load. I, like most people, want the most power possible without clipping the amp.
Thanks!
