[QUOTE="dB-r, post: 6166398, member: 574699"] This really irritates me when people go talking about something they know nothing about.... The design and parts that are in the AQ1200D are similar to the Sundown SAZ-1000D, NOT the SAE-1200D. Totally different design, much more power output. Sundown recently posted a test with the following results: @ 1 ohm - SAZ-1000D = 1040 watts (which would be like the AQ1200D) @ 1 ohm - SAE-1200D = 1770 watts (blew fuses at that point) The AQ amp likely uses IRF640 and IRF9640 outputs, which are great, but this is a design that uses N and P Channel mosfets. The SAE-1200D only uses N Channel outputs, Fairchild FDA59N25, we replace with IRFP360LC like in the SAZ-3000D or SAZ-3500D and 1000 other Korean made big class D amps out there use IMO the IRF parts are better. On the power supply side the AQ1200D uses like 8 IRF3205 or something similar to that, and the SAE-1200D uses 12 IRF3205. The SAZ-1000D uses 8 DFP70N06 which are similar to what's in the AQ1200D if not the exact same. [/QUOTE]
