Citrigz Posted February 9, 2018 Report Share Posted February 9, 2018 Can i please have expert opinion on why this may be happoning. Whenever i listen to music in my car my 2 10” kickers make a loud rattle noise not a Bass sound no boom no thump just a rattle sound. These 2 10s are not even a year old and i had them tuned at by a friend at Best Buy in the audio department. I dont know what to do about this Link to comment Share on other sites More sharing options...
8ten8 Posted February 9, 2018 Report Share Posted February 9, 2018 Your hearing mechanical noise via clipping imo...not a good thing. I don't know what best buy installers use to tune car audio systems but if i were you, I would invest in a multimeter at least. Using a multimeter only, will get you pretty close. Using a SMD DD-1 or an oscilloscope will get you damm near spot on. Research online: "setting gains" w/multimeter, DD-1, oscilloscope. The DD-1, CC-1 and multimeter are a must to start with IMHO Link to comment Share on other sites More sharing options...
alex912005 Posted February 9, 2018 Report Share Posted February 9, 2018 Might be coil rub. If you push on them with your hand do they make a scratchy sound? If so, they are partially blown. My Build Log Link to comment Share on other sites More sharing options...

ckeeler11 Posted February 16, 2018 Report Share Posted February 16, 2018 As others have said you are most likely reaching the limits of the subs and clipping. turn off bass boost if you have it on and retune the amp. Link to comment Share on other sites More sharing options...
