    The following is currently being installed:

    Proceed AMP5 (125 watts/ch) to drive

    - a pair of B&W SCM1's (rear surrounds)

    - a pair of Revel S30s (side surounds)

    - one B&W HTM1 (center)

    Proceed HPA2 (250 watts/ch) to drive

    - a pair of B&W 802's (main fronts)

    I noticed my installer used 14 gauge wiring all around.

    (I think the brand/model is Transparent Inwall 14-2).

    Now the question: isn't 14 gauge too small a cable for the HPA-2 and B&W 802 match-up?

    I don't know too much about HT (still learning) but even for my car (running 2 amps with total wattage of around 350), my car audio installer ran a 10 gauge cable from the batterry to the trunk. I would have thought 14 gauge for the HPA-2 is way too small....

    Any advice? Should I insist that the installer change the cables? (Additional info: room size is 22 by 17, distance from amp to speaker is about 20 feet).

    I think you will be okay with a true 14 gauge for runs up to 20ft. and up to 500 watts.

    If possible I would still have the installer change it to 12 gauge, just for piece of mind, but if it's a real big hassle a good quality 14 gauge should be ok.

    Use at least 12 gauge, high quality copper wire.

    Germain, I should have stated I personally wouldn't settle for less than high quality 12 gauge cable.

    I do not have as much power as you, but I still use Home Depot 12 gauge (which is good quality).

    Thanks for the replies, guys, as always, HTF members always comes through when I need help.

    Just to clarify, do you think it's necessary to change to 12 gauge for ALL the speakers or just for the 2 main front speakers (802's)?

    Also, does anyone know where I can find a chart/guideline that tells me what gauge wires to use for how much wattage?

    Thanks again.

    Hello Germain,
    I think you will be fine with the 14 gauge wire for your speakers. While I prefer 12 gauge for my front speakers, I use 14 gauge from my rears without a problem. I usually buy the best interconnect that I can reasonably afford and within my own personal definition of reason [​IMG]
    When you had your car system installed the 10 gauge cable that ran from your battery to your amps was actually your power cable and most likely not related to your speaker cable. This cable is analogous to the power cable that runs from your home's outlet into your electronics. I image your car speakers were installed with either 12 or 14 gauge speaker wire.
    Thanks,
    Jeff

    I forgot to give you this link that describes speaker wire in great detail and has a chart for appropriate gauge vs. distance. It was provided by another forum member (Nick G) in a previous post. It seems to be a good reference.

    Thanks again,

    PS - I would have edited my last post, but then I wouldn't be increasing my own post count [​IMG]

    Most of us prefer 12awg for the peace of mind that your

    covered.. It doesn't get better than 12awg. But when you

    look at the length of the run and the corresponding gauges

    recomended you are safe with what you have.

    I run 16awg RadioShack Navaho White CL2 to my rear surround

    and the run is roughly 32' and the speakers sound great to

    me.. (not just movie wise either, I play in All Channel

    Stereo most of the time)

    But I do run 12awg to the mains and the center channel which

    have substantialy shorter runs of wire but I wanted to use

    12awg and the price was right.

    While I use 12 gauge cable for my mai HT, I did use 14 gauge flat speaker wire for the music-only system in my basement (I wanted to feed the cable through the rails in a drop ceiling to avoid drilling holes in the paneling). These runs are about 25-30 feet each, driving four JBL N24 speakers with a 100 watt Kenwood integrated amplifier. For this application, the thinner wires worked fine.
