ok i have 2 10" rockfords with a vdrive 2800 crunch amp. visonic corssover pyrimid 4 chan amp and 2 power caps. it was all working perfect sounded great but today something happened to it and i dont know what i need to do to fix it my mids and highs are fine but as soon as i give the crunch amp power it makes all the speakers in the car go crazy and the subs just move in slow mostion in and out. why would it all the sudden do this? does any one know what i can do that may fix the problem i tryed switching rcas but that didnt fix it. and i noticed after bout 10 seconds when the amp is giving power and the speakers go crazy that it goes into protect and then the mids and highs just go back to normal the amps gain is all the way down. and all the power to the two amps are seperate from each other. i also noticed that it started to do it once i had sirius radio installed. could the incoming singnal from the sat be messing it all up? if you can help me out please leave a message or e-mail me justin.hofmann@Gte.net thanks.
