there is different gauge wire sizes in the power/ground and speaker wire? which is better? what is the difference? buy ground power and speaker wire the same gauge?
Use the 4 gauge wire (thicker) for your power and then the 8 gauge wire for speakers and ground. If you are wiring a stereo with an amp, its best to ground both at the same spot to reduce what is called ground loop. Otherwise, you may hear engine noise through your speakers and possibly clicks when using your turn signals.
properly, there are variations in conductivity in wires of the comparable gauge, based upon the textile of which the cord is made and no count if or no longer that's multi-strand or good middle. That sounds like an rather huge hollow even although. To account for that plenty variance i might somewhat much would desire to think of the decrease one is aluminum or some very low-cost copper alloy. 8 gauge is somewhat thick cord, in spite of each and every thing.
the 4 gauge is twice as thick as the 8 gauge.and the speaker wire should be speaker wire not 4 or 8 gauge wire.and 4 gauge is the way to go for power and ground off your amplifier.you can buy heavier speaker wire for your sub woofers from any car audio dealer by the foot.whatever thickness wire you use to power your amplifier is the thickness you use to ground it.and ground your amplifier as close to the amplifier as possible to a clean steel area with a self tapping screw and a o ring clip on the ground wire.both power and ground should be the same thickness.the speaker wire is up to you.
