Bronze Member Username: PvdukPost Number: 23 Registered: Feb-06 | Hi, I'm going to run a MTX Thunder 502 (2 x 90w RMS @ 4ohms - 12.5 VDC) and a Kicker KX600.1 (around 1 x 500w RMS @ 2ohms- 12.5 VDC). I was thinking of running 1/0 AWG wire from the battery to a distribution block (right near the amps), then 4 AWG to both amps. Then 1/0 AWG ground (from chassis at rear of car) to a ground distribution block (again right next to amps), then 4 AWG wire to both amps. Does this sound right, or should I just run 4 AWG wire straight from battery and chassis ground to the dist. blocks, then again 4 AWG to amps? I have a feeling it will be better to go with the 1/0 AWG straight away, just incase I wanna upgrade in future, etc. But will the main line 4 AWG work anyway with these 2 amps??? Thanks in advance guys. |

Silver Member Username: SolacedagonyNew Jersey US Post Number: 862 Registered: Oct-04 | Yea, like Ty said, if you're planning on DEFINATELY upgrading into 4 digit total Watts, I would run the 0 gauge, otherwise, it's way too much trouble. Just refer to Glass's link. |

Bronze Member Username: PvdukPost Number: 24 Registered: Feb-06 | Thanks guys, I'll go with the 4AWG main line. Also, I've been trying to find info on what gauge speaker wire to use for 150w RMS speakers and a 600w RMS subwoofer????? |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 11455 Registered: Dec-03 | 16AWG is fine for subs. 18AWG for components. |

Bronze Member Username: PvdukPost Number: 25 Registered: Feb-06 | Thanks Glasswolf. I have some 12 gauge lying around and the amp kit i'm getting provides some also, so I'll just be using 12 gauge for both components and subwoofer. Also, is there any difference at all in 'power' and 'ground' cables?? Could I use a power cable for a ground connection, and visa versa??? Thanks. |

Bronze Member Username: PvdukPost Number: 26 Registered: Feb-06 | Also Glasswolf, I was wondering why the gauge sizes for speakers are so big (smaller wire), especially for the sub??? One would automatically think that you would need huge wires for the sub (4 - 8awg) and medium for the speakers (10 - 12 awg)?? Is there a guide for speaker wire gauges? Or would you care to explain please???? Thankyou. |

Gold Member Username: B101Queen City, NC USA Post Number: 2155 Registered: Sep-05 | dude did u even read the link? http://www.the12volt.com/info/recwirsz.asp sub wires are not passing that much current to begin with! so 12-14ga is ideal for the subs, 12ga can pass upwards of 40amps, thats alot from a amplifier!! |

It comes down to current - Speaker wires are higher voltage than power wires so they don't require high current - which is the basis for wire size. |

Bronze Member Username: PvdukPost Number: 30 Registered: Feb-06 | Thank you very much guys!! One last question.. Is there any difference in 'power' and 'ground' cables?? Could I use a power cable for a ground connection, and visa versa??? |

Bronze Member Username: PvdukPost Number: 31 Registered: Feb-06 | Bump, someone please answer this quick question ^ |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 762 Registered: Mar-04 | yeah, that's fine. Just keep the color straight, and use the same gauge. I used red for both pwr and gnd in my wife's truck but I put a strip of black elec. tape on the gnd every foot or so just to keep them straight. |
