I been running my amp om Low Pass for ever and I now got a better amp for my subs and I've started to hook it up to my 6by9's and I'm getting that winning bad ground noise no matter where i ground it. Where is a good ground

try a noise filter. costs under $20 at any audio place. Get some for ur speakers and ur sub. Easiest way to do it is get them to install em unless u know what ur doing. THye jus go on the stock wires, and ur amp wires. Color coded so u cant screw em up!

You might need a ground loop isolator if you can't find a really good ground. You might need to upgrade your battery ground as well.

did you re-arrange the configuration of the wiring? Did you cross the power wire with the RCA signal cables? or get them close together? They should run down opposite sides of the car and be as far away from each other as possible.

Noise is not very audible with a low pass setting, as noise is mostly in the upper frequencies.
