Has anyone seen the new Audiopipe GM4-CLD class d amps in use? I have seen the numbers, and some test results from the manufacturing plant, and the numbers are kick a**. Showing max power @1650 watts!!! Rated and passed by USACI 300 watts @4 ohms 12.6 volts. Let me know if you have seen any of these amps in use, or their subs also.
