Quick question about "grounds" and hum/whine

[k3n12ock]

So I have this hum/whine still from my mids/highs. This started back in November/December when my sub funked up. I have since changed everything (new recone on sub, new sub amp, new mids & highs amp, new mids & highs, new HU, new power & ground wire, new speaker wires, all new RCA's). The one thing I have not changed is the EQ. Even with the rca's directly to the HU the whine/hum is still there. I've troubleshooted like a mofo and it's frustrating. Anyway, could having too many things grounded together be the cause? I have the grounds from the HU, EQ, Ipod cord, and Volt meter all together. Could that be the cause of it? I have also changed the mid/high amp ground to my rear battery as well; still hum/whine. Just thought I'd throw this out there if all the grounds behind my dash could be the cause. Will test it tomorrow.

A few notes:

-rcas are run on one side and power wires on the other

-rcas & speakers wires are not near any power/ground wires

-new mid/high rca's reduced the hum/whine a bit but still noticable

Have you ran a ground from your HU ground to your amp ground?

Are your RCAs ran on the opposite side of your power wire?

Do you have a pioneer radio? if so and you have done everything mentioned above, ground your RCAs.

A good way to trouble shoot to see whether its your signal or a bad ground, get an ipod with a 3mm to RCA cable and hook it up to your amp. if it still whines, bad ground. if the whine its gone, its the signal.
