    So basically you can only bridge 4 ohm speakers, not 2 ohm speakers.
    as long as the 2 channels are 2 ohm stable to begin with.
    yes.

    never say never. i've met plenty of people that think clipping and distortion are just what loud music sounds like. let them set by ear and they would just max everything and think all was well.

    it is useful to use the DMM as a check to see what RMS voltage you are getting out of the amp and if that makes sense with expectations. but you always fall back on what you hear as being your guide.

    usually, speakers need much less power so gains are lower anyway.

    thing is, they won't learn if you don't take the time to teach them. we cannot just say "listen for distortion" since that requires some hands-on training.

    using a DMM is safer and usually quite conservative. I have no issues recommending it to a Novice as it also introduces them to Ohm's law and gets them using a DMM. the effort teaches several concepts.

    This is true. But this is just one thing I don't about forums... I'd rather be teaching people hands on in person. I'm not the best at explaining things online.

    So why not set your hu atty 3/4, then just up the gain until you hear either clipping or distortion, given you aren't overpowering your mids.
    Clipping is obvious at 1khz.....
    @Buck ; @keep_hope_alive ;

    What about that that I mentioned earlier. Using a tone to set by ear.



    "When I listen to a stereo loudspeaker playback in my room and an auditory scene has formed in my mind, how would I know that what I hear is an accurate replica of an auditory scene that could be had at the recording venue? Or more generally, that this is an auditory scene that could have existed at all?"

    Re: Bridging Fronts

    It's definitely worth it to develope the ear to tune anything without needed other equipment. Idk, I have an ear for EQ'ing and setting gains. If you do it enough, it's very easy to tell when something is off.

    You don't need a tone. Set it on the music you play, heavy music with a lot of sounds, a lot of range in the spectrum.

    Re: Bridging Fronts

    tones would be easier than music, because music is dynamic and constantly changing.

    Autosound 2000 Disc 102 includes tones that intentionally clip for 3-4 seconds so you can hear what it sounds like. it allows you to easily set gains by ear.

    likewise. my efforts in person are somewhat different than my recommendations in forums. over the years i've honed my recommendations and general rules, knowing that many more people will read my posts than will ever comment on it (many non-members). so i consider my audience to be more than the OP but the general public and people all over the world.

    @bradl79 ;
    There's your answer.
    Of course you don't need the disk. Get a tone and listen carefully, you'll tell when it clips.

    And I feel like being technical right now lol, but the only thing I see going wrong with this is if your amp puts out way more than you're speakers can handle and you end up putting too much power to them before the amp clips.

    Of course this probably isn't the case in most situations.

    Re: Bridging Fronts

    setting with tones is pretty conservative anyway. even after you set gains, you use good judgement for volume setting. or PM me for links to those tracks.

    That's a very good way to think about. I'll have to keep this in mind.
