I have a Kicker KX600.4 (car stereo amplifier) running 4 channels for my speakers. When installing, I was a moron and had the stereo on, and accidentally touched the positive to an RCA. Two of my channels were making static low volume sound, so I hooked my two other speakers to the two channels that work, but of course, my speakers aren't all playing the music they should be.
I opened up the amp last night and tested all the mosfets (multimeter on resistance touching the two outer legs) and found two that read less then 10 ohms. All the other mosfets read in the megaohms.
They read,
on the left: ON; U1620R; CQ239; KAK
On the right: ON; U1620; CQ243; AKA
I can't find replacements online. All I could find is the U1620 for $9. Link to part:

Anyone know where I can find them or if I can substitute for a more common part? Thanks.
