35' subwoofer speaker cable run, 1000 watts, what gauge?
I am going to order a ~1000 watt pro amp and ART 351 EQ to drive my JBL Pro dual 15" bass bin subwoofer. I fully expect there to be 1000 watt peaks under some circumstances. However, the cable run (NOT low-level subwoofer cable, but high-level speaker cable) is about 35' and I am wondering what the appropriate cable gauge to use would be?
Would just any normal 12 gauge work, or would I want to go with something closer to 8?
Thanks!

I had around a 25 foot run of 12awg when I had my subwoofer being powered by a QSC RMX 1450 (1400w) and it worked just fine.
I doubt you would hear any increase in performance if you stepped up to 8awg, but it sure would look cool  |

Or I could go to Home Depot and get some 1 AWG from the spindle |

Assuming a nominal 8ohm load and ~1V max drop (~0.1dB), then 10ga suffices.

Yeah, and it would also be nice to know that you had some sufficient wire in the house - in the event your jumper cables didn't work either.

Here you go rat boy... http://home.earthlink.net/~rogerr7/wire.htm#wiretable a table which was originally supplied with McIntosh amps and speakers posted by Roger Russell (retired McIntosh engineer). If the resistance is 8ohms... you are more than covered with 12guage.
Later...

Good read Rob, Paul W. Klipsch swore by zip cord, and a McIntosh guy doing the same really says something.
Thats why I bought a 100' roll of 12 AWG from Parts Express for 3, 25' runs.

Kenneth,
Why can't you put the amp closer to the sub and shorten the cable. You'll end up with a longer signal cable to the amp, but that should be negligable.

Seth:
Well, what would cause less signal loss? A 35' RCA sub cable, or a 35' speaker cable run?
Also, I would like to have all my gear on one rack, and one one good surge protector.

I'll go with a 35' signal cable for $100 Alex.
I'd use RG-59 with male F connectors on the ends and then RCA to female F connectors. Will have plenty of BW, low loss, and best of all it's cheap.
