tboorn Posted February 17, 2015 Report Posted February 17, 2015 well if you set your amp with a -5db tone then any time you play any music that is recored with anything above -5db, the signal will instantly be clipped since the amp still is tuned to play at a -5db range, even though the amp is "properly set" it is still up to the user to control the music that goes through it and either adjust the volume (lower it) on the radio or retune the amp. amp gain is only half the fight theres still user error. your better off setting the gain with a clean 0db test tone so that anytime you play music with other -db tones the amp won't overcook the power. and theres potentially less room for user error unless you play ridiculous bass boosted crap Fidelity Built to Last Team Sound Asleep 24Runner Build Log: http://www.stevemeadedesigns.com/board/topic/196657-24runner-sleeper-system-lots-of-fi-neo-dd-focal-new-video-w-juicebox-lithium/ 2 x 12" Fi BTL N2 / 2 x 12" Fi BTL N3 2 DD M3b Maxwell 2.7V 3000F Supercapacitors Pioneer DEH-80prs Focal P165 V30 components Rockford Fosgate T-400.4
ben1994 Posted February 17, 2015 Author Report Posted February 17, 2015 When in doubt about clipped music, play it on windows media player with the scope and see if it is in indeed clipped. Never play boosted songs by people you DO NOT trust 1000%, cause you'll smoke a sub in nothing flat if the song is clipped to death. Windows media player with the scope is a very useful tool to use./ I don't mean to sound ignorant but is there an oscilloscope built into windows media player? or would you recommend downloading one and running in tandem?
RooTxBeeR Posted February 17, 2015 Report Posted February 17, 2015 Play music in Windows Media Player and run the scope visualization and put the speed to the slowest or can. And watch for the waves to go flat. If at any time they flatten, it's clipped.

firebirdude Posted February 17, 2015 Report Posted February 17, 2015 So you set your gains using -5db, but are playing music that you assume was recorded at 0db? Um?
MrSkippyJ Posted February 17, 2015 Report Posted February 17, 2015 -5 is a really safe level. F150: Stock 2019 Harley Road Glide: Amp: TM400Xad - 4 channel 400 watt Processor: DSR1 Fairing (Front) 6.5s -MMats PA601cx Lid (Rear) 6x9s - TMS69
firebirdude Posted February 17, 2015 Report Posted February 17, 2015 -5db input signal would mean you'd have to turn the gains up higher than with 0db to achieve the same power out. After the gains are set for -5db, you then go and supply a 0db input. -5db being generally acceptable or not. He's posting a topic asking why his subwoofer is burning up and we're just suppose to look past this?
MrSkippyJ Posted February 17, 2015 Report Posted February 17, 2015 What I am saying is he is very likely not supplying a 0db input, at the very least, not on average.

Smoove Posted February 17, 2015 Report Posted February 17, 2015 Have you tried playing the same tracks on a cd vs your phone/ipod/mp3 player. When I play the same tracks on my gen3 ipod that I play on my gen4 Itouch. Subs get stinky when music is played on the gen3 ipod. Played from the Itouch subs dont stink Also, I know a guy who had lvl5's that always stunk and he knows how to set his systems up (would demo for hours and never had an issue ). Might just be a stnky DC sub. 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/
ben1994 Posted February 18, 2015 Author Report Posted February 18, 2015 So you set your gains using -5db, but are playing music that you assume was recorded at 0db? Um? Where did it state I play music that is recorded at 0db? I asked if that was implied. I don't know what db the music is recorded at.

He's posting a topic asking why his subwoofer is burning up and we're just suppose to look past this? I completely understand what you're saying. From my understanding though, almost all standard music (non boosted) is recorded at or below -5db
