I think the old p10 is having electrical problems. I could hear my rpm's through the radio at minimum volume. as the rpm's get higher the noise gets louder also...what is the cure for this?

its an electrical problem, mine did it w/ the stock HU...so i bought a new (AEM) one, problem solved.
does it sound like an electrical whine? i have the same problem, but it's intermittent. and i've got an aftermarket HU...
Bad ground? I get it when I switch to AM on frequencies w/ lots of static

It's because theres a ground difference between your amp and your head unit. Should be fun to fix

i get the same thing. the amp gets power right from the battery, and the h/u gets it from the normal wiring (i believe).
what about those ground filters you can get from Radio Shack? Would that work?
my friends sentra does this on a few am stations w/ the throttle. we turn it up loud, and it sounds like a v dub. lol
That could help, but not neccesary. It is usually a ground issue that needs to be solved. It is best to try and reground hu and amp.

Sounds like a grounding issue to me too. Reground everything and you should be ok. And if you need a grounding kit, check my sig, im doing a GB on them.
Aww crap seems to me that I see a lot of potential problems that were mentioned..
1. My ground terminal is loose ie. after you nut and you start to deflate and condom starts slipping off. ----so i put zip ties to hold down the ground wire connecting to the battery.
2. I disconnected my amp and woofer so my wires are just dangaling in the trunk.
If this wont work out im going to get Mautai916 ground kit
that is one possability, but most likly it's a weak battery. see the battery "fliters" out most of the elcetrical junk, but as the batt gets older the stuff(not sure what its called) comes off the plates in the batt and some of the junk comes through.
what you are hearing is the alternator.
make sure your amp wire isn't real close to your plug wires, or distributor...if its not, then you got a bad ground...somewhere!

Had 96 DL0 5mt (modded and gone)
Now 02 KR4 5port
I actually have been having the same issues...whenever my radio is on and I have my cell phone holder plugged into the charger, I hear a slight "whine"...it's only at the lower rpms though and it goes away after that.....my holder has a speaker too and it makes awful noise when connected to the cig ligher slot.....my battery is fairly new........I wonder if I should just reground it.....
my problem is fixed I disconnected my wire to the amp from the positive terminal..
grounding issue eh? i guess when i get mautai's grounding kit i'll reground everything, see if that works
I redid the ground on my head unit. I have a Sony unit and it was spliced into the factory wiring. I snipped that ground, then grounded it right to the metal beside the radio, where the 4 screws hold the radio in. Still have the same problem.
Doesn't matter what I play, AM, FM or the CD Changer i still get the whine.
Like I said before, the amp (in the trunk) gets the power right from the battery. The radio power from the stock wiring. The amp has a big black ground cable, but where its ground I don't know. It goes to the drivers side up over the rear suspension tower someplace. Is there a good ground in the trunk someplace that I can add another ground?
As far as I can tell, the RCA cables from the h/U goes down the passenger side to the trunk, to the amp.
i've still got the same problem too, but my alternator is going bad on me. i'll update as soon as i install a new one.
its the ground
Oh i noticed there is a big ground in the trunk, underneath the carpet! Can I connect the ground to this? Then the ground from the amp will be less than 2'.
