Hi everyone. New here and looking for some direction. I am new to djing and am looking to buy a new amp as the one I have broke. I am looking for some direction.

I have 2 pv115s, 400 watt 8 ohms that I run in a series. I have 1 PV 18 inch sub, 400 watt 8 ohm. I am looking at a berhinger inuke 2 channel. I know a built in crossover is a must, but I am having issues trying to rack my brain around the ohms...

If I run an inuke 3000, 1 channel to the tops and one channel to the sub, will I risk blowing my sub if it is 1500 watts per channel? Also, what ohms should the series be running at?

I k ow these are basic questions that you guys probably here alot, so I appreciate any help. Thanks!
