    Tech question about 2 chan. amp running 1 ch. at 2 ohms

    Ok,,, I am lookin around all sorts of sites that sell amps and for the specs i never see ex. 200watts x 1 rms (2ohms) for any amp that is 2 or more channels. But... it often says ex. 100wattsx1rms(4ohms). so can a 2 channel amp be bridged to one channel and run at 2 ohms?

    Another side quetion for yah,,,,, if i get one of those 50x4 pioneer decks can i bridge any of those channels?

    Thanks

    You can run an amp 2 ohms mono. Chances are though, that it will over heat within a couple minutes.

    What happens when you bridge an amp is that each channel sees 1/2 the load. So if you bridge and run at 4 ohms, the two bridged channels see 2 ohms each. If you bridge to 2 ohms each channel is only seeing one ohm. Not many amps are built for that kind of current.

    And I do believe there are a few recievers that have bridgeable channels, but they're only going to give you probably 30-40 watts rms so it's really not much of a gain, especially if you're wanting to power a sub.

    That kicker amp seems pretty sweet,,,,,, I am just wondering cause i think that the 75 x 2 would be used for mids and highs but i havent seen any ex. 2way speakers... that are 2 ohm. So how would you wire them into 2 ohm so that you are still in stereo?

    I hope u get what i am sayin
    thanks

    I wouldn't try to bridge an HU amp. I doubt that most HU amps are 2 ohm stable. Besides that they are not built to dissipate the heat that the internal amp would create resulting in poor performance anyhow.

    2channel amp

    crazydude 133--- you can wire a 6'' mid bass
    a 4'' midrange and tweeter on one channel
    for a 2ohm load in stereo
    or a pair of coaxles on one channel
    for a 2ohm load in stereo
    on the kx 550
    then use the 3rd channel (class d
    for your subs
    you''ll be better off using a amp(more power)
    then you would be trying to bridge
    your headunit
