[QUOTE="ccajun4real, post: 2502299, member: 569654"] I got my system up and running yesterday. I took one of the grilles off of the front 6.5 coax speaker and noticed that the speaker cone is pulsing back and forth (like a heart beat but slower). It pulses about every second. It does this no matter what the volume is set at and only stops when I turn the volume all the way down to 0. I am running two Focal 6.5 and two Infinity 6.5 from a single 2 channnel JBL amp so the ohm load is 2 ohm x 2 ( I am pretty sure). What are the possible causes of this pulsating? Should I not run these speakers at this load? Need some help, dont want to hurt anything. I have cranked it up and it seems to sound very good but I know this is not normal and can probably cause some damage so am leaving the system off until I find out the cause. One other thing to note is that the pulsing did not start right away. It either started after about 10mins of operation or after I cranked the volume up to 80% without distortion. Thanks for any help in advance. Cajun [/QUOTE]
