[QUOTE="gckless, post: 7460956, member: 635756"] I have to agree with this! ^This. Before I get to that I want to say good write-up. Not trying to be rude, but I did understand everything that you said. It is all valid. Ideally, you are right, external fans on a passive amp are the best way to go, and honestly I prefer that as well. Less things to go wrong. You don't have to worry about a fan dying, and then pray that the amp's thermal protection works correctly. But I am trying to go for the cleanest install with the least amount of extra wiring to do, and an external fan doesn't lend itself to that. It can be done for sure, probably easily at that, but it's more work than I want to do and/or above my skill level [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] So that brings me back to either a passive amp, no external fan, or active. I am excessively paranoid about heat demolishing components, I guess I can probably blame that on my job, so I am really leaning active.
