To me (and Tom V of Power Sound Audio agrees) heat is not a good thing, and will shorten the life of the amp.
I have 2 Legends, and the amps get hot to the touch...very hot. But they have been fine for over 7 months.
I replaced them with Power Sound Subs, because I want to feel the bass below 20hz, and I'm an upgrade fool.
15hz at 115db is kinda nice.
Seems that the customer service issue has been straightened out somewhat....so buy dual Legends for
800 bucks, shipped. The amp warranty is 3 years. I've never seen a deal like that, two dual opposed
12" woofers for $400, or two subs for $800, and free shipping. Sale is time limited. I paid $1100 for my duals
