That's just a general rule of thumb... power lines can cause interfereance, and your speakers could pick up engine whine or other undesireable noises. The bes t thing to do is keep them as far away as possible, and get shielded rca wires instead of the cheap ones. other than that the wiring connections depend on your system and your car.1200mk said:how would i go about wiring a 94 integ..... ive heard that you have to run the rcas and power separate? is that true? anyone have online tutorial? thx.
