Here is some info I received from PA (Power Acoustik, who makes Kole) on the Kole HK980-2 and Kole amps in general:
The amp lines HK and Q are the same, just the name and heat sinks are different. Kole amps are very similiar to the Power Acoustik amps. The HK980-2 has two 35amp fuses in parallel and has a dampaning factor of 200. So the amp should be able to do it's stated RMS power if I understand how the fuses are working (35amp per channel).
I've also read (from others who sell them) that the Kole Digital amps are the same under the hood as the Planet Audio Digital Amps or at least the Kole 3000D is the same as the Planet Audio 2500D.
A friend of mine is a distributor to them. He says:
"They are too new to really have any long-term feedback but everyone else who has them is receiving good feedback on them. PA makes solid stuff, especially for the price. I have never been disappointed at PA's performance and Kole is the upline to both PA and SPL."
I hope that helps. I can't comment because I haven't heard one but it sounds like they should be fine.
