Awesome amp!!!

This amp is the most durable amp I've ever seen. Ive had the Hk1997 which is the older model of this amp for about 4 years now and it has not only put out some serious power its never even once overheated!! I don't ever think I've ever felt it get hot and I've blasted my system for hours at a time. I recently purchased an hk1998 and its just as durable and powerful as the 1997.
