us acoustics usx600d questions

[el_chupo_ 10+ year member]

I recently bought a usx600d to power an alpine type r. The website says this amp is rated at 250Wx1 @4ohm, 375W x1 @2ohm. The manual that came with the amp states that it is puttng out 200x1 and 300x1, respectively, all at 12.9v. Which of these numbers is correct?

My other question has arisen because of a post on the board that said they used such small fuses(20 amp) because this is what is required for the 4 ohm load. I will be running the type r at 2 ohms, so do i need to replace the fuse with a bigger one? thanks

Do not worry about the fuse.

My guess is the website might be rating the Watts off of 14.4volts.

i just double checked and their web site says its at 12.9 v.

75watts is pretty nominal when you are talking 300 to 375, dont worry about it, its a great amp.

I know it is not much, but i just wondered if anyone knew off the top of thier head. If no one does, no biggie, im still using it for the sub...and i know now not to worry about the fuses... thanks
