i find that when i run my sub full out for longer periods of time(1-2 hours) the sub amp gets really hot and will ocassionaly turn off, mostly when its really hot and the car is jsut sitting there(not moving) or when the a/c isnt on, i found this cooling fan on a website http://www.audioblowouts.com/Car_Audio___Electronics/Accessories/Amplifier_Kits/ Pyramid-PBFC-6713 the only problem is that i think it may be allitle to deep, b/c my amps are attached to my box which are directly behind my rear seats...does anyone know of any other type of fans i could use, different company who makes them and where i could get one...thanx in advance...killer44
Yes any 12 volt will work I had the same prob with my rock foz 501x 4 ch. I used 3, 5 volt fans that are from a computor parts store,They are less then a inch square and put them inside the case! also i used real small heat sink's from same parts store,glued them in with thermal adhesive and have not had a heat issue at all sence!

Also you might want to look at your cap's on the board! Look to see if they are buldging on there top's? If so i would replace them! I found this site looking for my caps, anyone know where to find 4 capacitors for a rock foz.501x 4 ch. There a inch tall and are 3300 uf and 50 wv?
