Hey.
So my system is as follows. Stock head unit in a Pre FL 04 2.5i. High-lo adaptors from head unit to RCAs to power Option audio OAK75 with aftermarket wiring to fusion splits front, sony rear fill speakers. Second set of RCAs to a Option audio OAK300 apm to a boot mounted JVC drivn sub.
Amps are powered by stinger 4guage wiring to a 1 in 2 out splitter for the two amps. Stinger RCSs. 12g speaker wiring. 4g earthing wires which are to separate earthing points. I have recently put in 2 noise isolators inline on the rcas for the speakers. I have pulled the wiring system apart several times now and i have run all wiring as far apart as possible. I STILL have noise in the system. I am after any ideas at all. I am willing to try anything at this point. I still have to run the two earths to the same point because its been suggested that it might help. Other then that i am at a loss.
All suggestions welcome.
