amplifier static

So I make a hard left, to then experience a LOT of static in my speakers. Driving a Scion tC 2006, Rockford R150-2 Prime running two Rockford speakers in the front. Back speakers are still stock running off the head unit. Some Kicker amp running 2x 12" Comp Kickers (Older style) The amp giving me trouble is the R150-2 Prime. I've verified ground resistance is good. Power, sufficient. The RCA cables are perfectly fine. However I've come to a specific area on the amp I can assume the problem may lie. In High-Pass and All-Pass modes on the amp, I get the static. Speaker STILL plays the sound output from my head-unit but still far too much static to make it bearable. However, in Low-Pass mode - no static is heard. The speakers are capable of playing low notes at low volume to which I can hear them operate just fine playing the low notes however in both high and all pass modes, the static is present. It doesn't matter if the engine/car is running or not, static either way. Any suggestions? All wiring seems proper. I'm wondering if something came loose in the amp in which case I'll open that sucker up but I'd rather see if anyone else has experienced this before?

My recent crap noise was due to poor connections in dangling wiring, however that cap apply to any connection anywhere including dry solder joints and track cracks. How did you verify that ground resistance is good - DMM Ohms, or a reasonable load (and maybe DMM volts)?

I'm an automotive tech, fairly good with electrical, so I can definitely say the connections are all good. Ground resistance is less than .1 Ohm and voltage is more than sufficient.

the fact that the static goes away when the amp is set to low pass would mean that the static is probably coming from somewhere other than the amp. as oldspark said, dangling wires with loose connections, probably your rca wires. could be that the rca jacks on the back of the radio or at the amp could have a bad connection when g forces are applied. dose the static come from both speakers or just one? if its just one, it could be a sign that one of your speakers is about to die, or maybe the speaker itself isnt mounted securely or its maybe too close to some metal in your door and the terminals are momentarily making contact when you turn.

And keep in mind that 0.1 Ohm GND resistance is VERY high - even at a mere 10A that's a 1.0V drop!

The .1 ohm is more than likely in the leads of the meter. But just to make sure it is not, check voltage across power and ground terminals of the amp with the system playing at near maximum.
