Message	8 Ga. is pretty standard for a single amp. 4 Ga. is better for a multi-amp system because it will flow more current. Smaller power/ground wiring creates more of a choking effect due to resistance. That's why bigger is better in the land of power/ground wire. Bigger wire = less resistance to current flow. Always use the same gauge ground cable as you use power cable. Keep ground cables short. Think of cheap jumper cables. The cheapies use small gauge wire and as a result don't work as well (or not at all) as the beafy more expensive cables that use a larger gauge. Distance also becomes a factor. The longer the distance you need to run your wiring the larger the gauge you'll need to flow the same current without appreciable loss in the form of heat due to resistance in the wire. Speaker wire on the other hand flows AC not DC so wire gauge isn't a factor. I'm running 0 gauge power and ground cable, but I was able to get it for free. The Phoenix Gold terminals for that shit weren't free, but at least I know my power wire will never be to blame no matter how much amplification I use. Good luck. Steve

Impedance/Overheating, or shorting of some kind (n/m) - Z_PREPared 01:49:09 05/14/03 yup.... Its not speaker wire (n/m) - down5hift 09:53:21 05/14/03 agreed, I'm betting on incorrect speaker wiring (n/m) - onlinediamond 10:15:40 05/14/03 10 gauge power wire? - Spee 00:53:25 05/14/03 2nd. 10 Ga. power/ground is a bit small. Use 8 or 4 - Z_PREPared 02:04:23 05/14/03 10 gauge is plenty. - John P. 10:46:15 05/14/03 I disagree. I would use no less than 8 gauge. (n/m) - Spee 11:44:34 05/14/03 Why?>> - John P. 11:55:47 05/14/03 running a 400w amp for a long time gets things hot. - Spee 14:24:41 05/14/03 Use 4 gauge reguardless. Maybe you'd want to add more later (n/m) - JustinChien 01:35:10 05/14/03 sure, 10 awg is a little small for power wire, but - Altersys 02:24:14 05/14/03 Im 99.996% confident that your amps ground is insufficent - Bobby12many 08:38:21 05/14/03 I have had 10 gauge on my single bridged amp and single sub> - Unluky(MO) 08:57:35 05/14/03 i used 8 gauge on bridged 400wtt rms amp to 1 12", no probs - komplexZ 11:37:37 05/14/03 make sure you have a good ground too (n/m) - komplexZ 11:39:36 05/14/03
