The best way to do that is to run a new speaker wire from each amplifier output to each speaker. A ruler or paint stir stick makes a good wire-pushing tool. 4) The very worst thing to do is to bundle up power, speaker, and line and mic-level cables together. always want to keep your RCA's and speaker wire away from power wire, its easy to just run the power on drivers side then rca's and speaker wire on the passenger Dec 23, 2009 at 11:48 PM #5 Tahoewhat Ballin' on a Budget Supporting Member According to NEC 300.3(C)(1), you can only run the speaker cable in the same enclosure as a higher-voltage circuit as the insulation of speaker cable is rated for the voltage of the higher-voltage circuit. 3) If you must run things parallel, move things as apart from each other as possible. Also to know is, can you run speaker wire and electrical wire in the same conduit? When running new speaker wires from your amplifier's output to the speakers, any size wire from 18- to 14-gauge will work fine. my quesiton is can I run my speaker wire alongside my power 16ga power wire for about 10 feet? I have a path through which I'm running some speaker cables behind some crown molding. RCA cables come in stereo pairs, in various lengths. So you'd want to go with an RG-8 or similar versus RG-58 or RG-59. It won't be a huge degradation, but avoid if possible because it will introduce some interference to a degree. Likewise, can you use low voltage wire for speakers? The power wire will only powering some leds by the speakers… Speaker-level signals are not very prone to picking up interference, so it's okay to run your speaker wires near power cables. RCA cables and speaker wire Amp wiring kits often don't include signal wiring. If a speaker wire was run for a long enough distance right next to a power wire, then you might hear a bit of hum out of the speaker. Subsequently, question is, can you run speaker wire next to RCA? As a general rule of thumb, whether in a vehicle, home audio, etc., never run POWER cords next to AUDIO signals (RCA's, Speaker wire, etc.) If there’s a doorway between the power source and the speaker, run the wire all the way around the other side of the room to avoid it. Select Proper Wire or Cable: Make sure you use UL rated in-wall wiring that meets local building and fire codes—including CM, CMR, or CMP for computer networking, and CL2 or CL3 for speakers. If your subwoofer is actively amplified, the coax for it is shielded, but it will carry a lower voltage pre-amp level signal that may also pickup interference from running parallel to the power … If the cable for the rear speakers is unsheilded 2 conductor wire, it very well may pick up a 60 Hz hum from the power line. I've heard that your not supposed to run your main power wire next to RCA's? But if you keep the speaker wires about a foot from electrical wires and run these in a "normal" size house, there should not be any noise. I would like to use the same path for two 12 gauge speaker cables for about 25 ft. Will it cause interference to have these cables running next to each other? Click to see full answer. The point here: Don't simply assume that you can or should use old style category 3 cabling for voice. Use 14- or 16-gauge wire for speakers, 12- or 14-gauge for subwoofers. If you're going to run a separate cable for a phone, match the data cable type. If you want an effective shielded cable, you could use coax, but for a long speaker run (over 30 feet w/8 Ohm speaker, 15 w/4 Ohm, 7.5 w/2 Ohm) the narrower varieties of coax might add a bit too much resistance. If true or not, that isn't my question. You ever see one of those "clamp ammeters" that read current from clamping the probe over a coated power wire without ever actually touching the bare wire? Don’t use anything sharp that might cut into the wire’s insulation.
