White/static noise help

[Dbraves8]

You could have to turn your amp gains up so much that you're getting noise. I always recommend a 4v+ pre-out radio. 2v are almost useless.

I think thsts the problem. They are rated at 3volts but I only see 2 volts at max volume. Im worried I have clipping from headunit with max volume. Im using 35/40 and seeing 1.2 volts or so. I tested the theory of 10k hz tone and at 25rms per channel from headunit I get 10 volts. So I'm guessing 35 is max before distortion. I ordered 2 pac ground loop isolators to see if thst fixes the issue. I think its floor noise because at 35/40 and gains backed down vs 30/40 with gains up more the noise was louder and more obvious. If those don't do the trick then a equalizer with built in line driver will be next. Its just weird how when using the 3.5mm to rcas and bypassing the radio the noise diminished greatly.
