Summary: I have the 400msx which is just a mono version of the 400sx. I have this wire up to 2 MA Audio subs wired for a 2 0hm load and crossed over @ 80hertz w/ 7-8 db of bass boost. This thing makes those subs pound harder then any amp I've had this these subs hooked up to.
Summary: Just wired up my 800sx with three MTX thunder 6000's. What a bang!!!!!! Great amp pushing 600 watts to my three tens wired in parallel for a 4 ohm impedance. With the gain at 1/4 my Impala became a high powered vibrator. Great look, great price, and even better preformance.
