[QUOTE="Jeffdachef, post: 8646991, member: 650438"] yeah its not a garbage 2k if thats what you are thinking. Solid korean built, tank does 2700 certified at 1 ohm resistive on the amp dyno. [URL="https://www.youtube.com/watch?v=_Qr8uhLD5tA."]https://www.youtube.com/watch?v=_Qr8uhLD5tA.[/URL] Your prime does about 1400 watts at 1 ohm resistive. [MEDIA=youtube]dSNUujbayF4[/MEDIA] Only certified numbers matter here. Your system IS small and no it does not pull 200 amps of current, not even close. This is from you not understanding how recording levels in music works and what impedance rise is. You wire to 1 ohm, you are not going to get 1 ohm at all, as the coil moves through the magnetic gap, the ohm load shifts.
