[QUOTE="I Like Waffle, post: 6090529, member: 600248"] This weekend we took a trip to VA in my gfs car, and were just riding down 95 with the windows down so no ac or anything, i figure it was probably 100 degrees or so that day, hot as ****. Anyway, we were playing some luda i think and the amp starts cutting out, like itll stop, play one note, then stop some more, kinda like it was sputtering. So i go through the hu and turn the sub off till we stop at a gas station for me to check it out. So i get my meter out and a screwdriver, first thing i do is take the cover off the amp and im getting voltage to everything, so i pull the speaker wires out and check those individually, and the coils read good, sub feels fine. Amp was hot as **** though, so i figured hmm mustve been thermal protect and we just leave it off for a little while. Turned the sub back on when we got to VA and it played like normal for a day or 2, but a couple times it would slip up and kinda stop putting out like it would usually. Like all of a sudden the sub would play at half volume or so. I went to the HU and just for the hell of it put the bass on plus 6, that made it sound normal. I turned it back down and turned the sub off when that happened though, didnt wanna **** anything up. Same thing happened on the way home last night, and i know the amps not putting out full power for a fact when it does this. Normally id have to keep it down at night to keep the voltage up at a decent level, but if i turn it up to normal listening volume at night it would drop to 13-13.5. I turned it up playing a test tone that will drop it to 12.8 with the lights off and it didnt drop past 14 [IMG]//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif[/IMG] What could this be? the problem seems to only happen after long periods of playing music, so im gonna assume its a heat issue or a protect feature in the amp? Clifs - was driving, amp started stuttering so i checked everything out, amp was hot as ****. - amp will sometimes all of a sudden play at half volume or so, also decently hot - want to know why amp does this Incase you were wondering the setup is an m500 and a single PB 12, seeing 500rms or so [/QUOTE]
