Car Forum / Driving, Maintenance, Tuning / Car Audio / July 2006My amplifiers got really hot today
My amplifiers got really hot today, it hit 93 degrees fahrenheit outside and even with the 5% tint, I couldn't keep my hands on them and they weren't even on all day, cheap crap LOL. > My amplifiers got really hot today, it hit 93 degrees fahrenheit outside and > even with the 5% tint, I couldn't keep my hands on them and they weren't even > on all day, cheap crap LOL. Think cooling fans in an enclosure.  SignatureI. Care Address fake until the SPAM goes away ;-} I changed my setup the amps are right on top of the box. The amps got hot from the sun, I didn't even run them today. Not sure if these amps were made to run super cool or if I'm being just a wimp a.s bitch with them but even after 2 hours of hammering my subs they just don't get hot. I can feel more heat in the center of the sub cones then on the amps which is just a barely noticeable temperature change from the coils. >Think cooling fans in an enclosure. >I changed my setup the amps are right on top of the box.

That's all that's going on here -- it is pretty impressive though, when you think about it, that the Sun can heat something to that temp from over 90,000,000 miles away just by shining its light on it. Dat's a pretty hot fire ya got there, don't ya think? PD they're doing their job then. just hope they're doing it as well as they need to SignatureKU40 > My amplifiers got really hot today, it hit 93 degrees fahrenheit outside and > even with the 5% tint, I couldn't keep my hands on them and they weren't even > on all day, cheap crap LOL. Electronics can often run at 180F to 200F for moderate periods of time. It speeds aging of the electrolytic capacitors and solder joints but doesn't do any immediate damage. Many modern semiconductors can be operated at over 300F as long as power de-rating is taken into account in the amplifier's design. >>My amplifiers got really hot today, it hit 93 degrees fahrenheit outside and >>even with the 5% tint, I couldn't keep my hands on them and they weren't even [quoted text clipped - 5 lines] > operated at over 300F as long as power de-rating is taken into account > in the amplifier's design. Thought I'd add a topic-related link.... http://www.bryemsys.com/prod01.htm I know my RF P8002 Gets hot as hell around here [Northern Virginia, i gets near 100F some day] but ive never heard a decrease in performance and the amp has yet to go into thermal protect, although it did when get rid of my audiobahn and ran it for 30 minutes @ full tilt on a 10H note, it didnt like that @ all, i couldnt even touch the thing -- Luda > I know my RF P8002 Gets hot as hell around here [Northern Virginia, it > gets near 100F some day] but ive never heard a decrease in performance, > and the amp has yet to go into thermal protect, although it did when i > get rid of my audiobahn and ran it for 30 minutes @ full tilt on a 10HZ > note, it didnt like that @ all, i couldnt even touch the thing. I dont think I ever had an amp that DIDN'T run hot when I'm pounding em.. I've ran RF's in the past and I have Kickers now, they've ALL shut down via thermal protection if I don't have fans on em. I run them in pretty tight spaces though, but still, how can amps NOT run hot?? 12v fans on ebay are really cheap, I use ones made for PC cases, standard 80mm.. My amps wouldn't last 1/2 hour without shutting down if I didn't have em. LED fans look cool too, not that you can see em in my setup anyway.. oh just so you know. i'd never use rf/kicker amps! lol you a tool of advertising n price/proformance ratio..... theres no connection in higher price better proformance.lol My home monoblocks get extremely hot all the time...that's what a 20% operating efficiency does :D SignatureJimJ[VT] that's what a 20% > operating efficiency does :D And that's a good thing? Oh well, I guess if it sounds good. MOSFET you know i've never had a amp run hot. or even very warm.in 15 yrs. of coarse i never run amps over 85% of max power. only an idiot would. and then short periods of time. i think you should call usa dept of consumer affairs.tell them you ran amps high volume for hours in very hot weather n they got hot? ''wtf! must be a defect in design.lol you kids tear me up. lol |
