Well...soundstream tech told me there is abolutely no internal changes between the old and new amps, other than the outside wire connections.......
However he also stated in 20years of car audio he has never heard of an amplifier causing radio interference and their amps put out no where close to a frequency that would even come close to fm interference. However a quick google of class D amps and reception seem to show otherwise. So there is a glitch on some instances of this combination. Hopefully we can get to the bottom of it eventually.

I'm hoping the statement above about using a thin sheet of lead inside the cases is true to fact with the new models.
Has anyone out there installed a new style PN4.520D with the speaker block on the side running a stock head unit and stock whip antennas verify that you have no FM interference issues?

"wink"). I also edited my post (see edit note) to show that it was totally without merit and that I was just trying to achieve my 300th post milestone.So in keeping Politically Correct, I ask the forgiveness of anyone who may have been harmed by my words. I promise to keep On Topic in the future and not to spread viscous lies & rumors.

If you'll do the swap, if I do decide to swap, I'll just give it to you. I don't know how to troubleshoot an amp (no spark/fuel hah!), but I think something's wrong with it.

MY BAD! My post was meant as a joke (hench the "wink"). I also edited my post (see edit note) to show that it was totally without merit and that I was just trying to achieve my 300th post milestone.

yeah he doesn't have a clue what he's talking about. Switching outputs by nature whether it be an A/C generator, a 12v converter, or an amplifier emit EMI. The trick is isolating that EMI and apparently the FCC doesn't do a real good job of policing that so the manufacturers get away with more than what's "allowed".
