Default wiring question-keep the amp power, speaker wires away from input wire? or???

Hi...i need some help. i read in a post that u should keep the input cables as far away from the amp power and speaker cables. Is this right?

would it be bad if the amp power and speaker cables are side by side? im asking this because after drawing many diagrams for the best wiring routing, setup for my system(components, back coxials, 4 chan amp) , i think the power cable for the amp is going to end up running side by side with speaker cable going to my front left speaker...from the amp and to and under the front left door sill.
would this be a problem? thanks.

also would it be best if to try to keep the amp power cable, speaker cables, input cables away from each other as far as possible? any 2 wires i should especially keep away from each other? thanks alot.

-gary

Run the power cable down the left side of your vehicle. Your RCA cables and speaker cables should run on the right side. You can get your left speaker wire to the left side by going under the dash and avoiding the power cable all together.

Your power cable will cause noise in your system if your RCA's or speaker cable run next to it.

This is 100% correct... Also if you have to cross the power cable anywhere in the system cross it at a 90 degree angle if possible.

thanks for the help!! so i should keep the input, speaker wires away from the power rite? hmmmmmm.....

chris: i have one question though if i run the power cable on the left side and run it thru the rubber grommet by the clutch pedal to the battery. when i run the left side speaker wires in the dash around to the left side wouldnt the power cable and speaker wires be close to each other? especially if i have to run the power cable on the left side going toward the front of the car....while the left side speaker cables are running from the right of the car(amp under passenger seat)...to the front.....along the dash to the left side of the car...and then from the front left..to the back left of the car? did that make sense? do u understand what im trying to show u? thanks

Run the rear left speaker wires down the middle, then over to the left rear door under the driver's seat.
To minimize noise from a ground loop, run an 8 gauge ground cable from the amp to a common ground point with the head unit.

I had my cables run next to each other for years. never had any noticable noise or distortion. I was running two 500 watt subs so there was a decent amount of power going through there. I'm not an electrician er anything, but you'd think as long as you didn't have any tears and a good thick coating around your wires (the importance of good wires) it'd be fine.
