Larger cables and signal?

    Do longer speaker cables weaken the signal? I need to get a new cable, and on the ampeg site it says use 18 guage or bigger. I called my local music store, and they said they have 18 guage in 6ft, and 16 in 12ft. What would be best to connect a head and a cab?

    This subject always seems to create a fire storm. For short runs at power levels of about 300 - 400 watts or less, you cold get by with either gauge. The cross-sectional area of copper doubles as gauge drops three numbers. In other words, a 16 Ga. cable has almost twice the copper per foot than a 18 Ga. cable does (if 15 Ga was readily available, it would have twice as much copper as 18 Ga.).

    Based on this and the info that you've given, the 6 ft. cable would have slightly less resistance than the 12 ft. cable. However, I'd go with a 12 ft. speaker cable because it gives you more options on where you can place the amp and cabinet relative to one another.

    Thanks, and could you steer me in the direction of another thread that already covered this or the search term?

    There are lots of ugly threads out there where folks start arguing about whether premium brand speaker cable sounds better than plain old jacketed cable.

    If Ampeg gave some guidelines about power level/length/gauge...I'd follow them and be done with it.
     
  5. Look under the recent thread titled "shielded/unshielded cables". In particular, read the article that PsychoBassGuy linked to.
