I have A pioneer deh-p9600mp and when i turn it off and on all my speakers and my subs make a pop noise and it makes the noise yoiu hear when the cd player reads the disc and makes poping noise it did the same thing i figured out it was'nt my amps but it was my cd player so i put my new deh-p9600mp work fine for 2 days and when connecting my speakers to the correct channel on the amp and it started again, I put my brothers amp in did the same thing, checked the ground with jumper cables to the battery, checked the ground and power on the cd player with same method, I also installed another capacitor shortly after this problem started but i took it out and it still does the same. and when i connect my speakers to the cd player amp it does not do this but only when connected to the preamp out puts?

 

What kind of amp/amps? sounds like bad RCAs, or RCA routing, try this, run a set of RCAs from HU to amp/amps down center of car on top of everything, just a test,also check for groundloop run 18 to 16 gage wire from HU case to amp/amps case, try this ,let me know.

hope this helps. 94
