Guts look about like a 2k amp.. Pretty sketchy if it has a strapped RMS rating on the front of the amp

It doubles as a dishwasher???

lol, but in all seriousness... I realize that's a typo

 

[akadj 10+ year member]

I guess I'll fill in the blanks...

Its a Zenon board that's used in... iirc old sundown saz3000, atomic at3000, Rd 3250.. ect.

Still have yet to put it to a test but will try in the next few weeks.

Price was right though.

I wasn't sure about them either... But then I did some testing and I'm pretty impressed ... Here's a video I made
