Dealt with them before, or only heard good things?

And if the RMS from the HU and the RMS from the speakers don't match up, find an amp and add the RMS to that plus the HU's RMS and see if that together reaches around the speakers/sub depending on the situation?

It's just, the HU is 18 and the amp is about 14, but I think the speakers required 50, so aren't I really kind under powered? All assuming What I just said was right.

And thanks again!
