Yes monoblocks are 1 channel amps. Im not sure about the power ratings though. you might want to do a little more research into the company to see if they are honest about them.

yea u want to double check that

how do i do that?

2000w isnt what is RMS at because the power is rated in max power try to find the RMS rating's for that amp

ans if its got 8 gauge inputs definelty it doesnt put out that much

you must have forgot, I have a 4 gauge wire throughout the whole system. I guess I said it right. It is a 1 channel though, right? And if it is, what is the RMS, 900 watts? I am not good at the amp language.

yeah normally on a good amp its about half of it peak wattage :?
