    Default audio tech

    Im looking for an radio/amp tech to help with an speaker and amp combo that i have and thinking of installing in my boat.
    They will be out of the weather and water so car stuff should be fine.
    I know the amp is a 2 channel so 2 speakers to each channel.

    I know very little about amps and radio.


    I have 4 Kenwood KFC6982ie 6x9 speakers and a Sony XM-GTR2202 amp

    will this combo work ok

    It will work but you would be alot better off getting a different 4 channel amp.

    I for got to tell you this is going in a friends 25ft cuddy cabin. all 4 speakers will me mounted on one board/box so we will not need front to back or left and right. But with the two channel amp we will have L and R any way. Thats why I was thinking it would work ok.


    What Amp would you use in this setup???

    the speakers i think are rated at 125w rms 500w max @ 4ohms

    the amp is 220w x 2 @ 4ohms rms I think it was

    SORRY if i sound like dumb ass!!! Im just not a radio guy, just useing my redneck thinking. And trying to learn somthing at the same time

    Thanks for your time


    Im sorry just found the audio forum will be moving there

    Right! Use one speaker per channel. Unless the amp is setup to be bridged, I wouldn't do it

    You can not do that (parallel) unless the amp is 2 Ohm stable. (stereo)
    You will cook the amp OR experience continuous shut down.

    If you wire 2 speakers per channel in series, then the amp sees an 8 0hm load per channel and produces half the rated power, but will not fry.

    You COULD run 4 speakers per channel, (2 pairs in series, at 8 OHM per pair, then parallel'd back to a 4 Ohm load) but the power to each driver at that point will be very low.

    Lets see if I got this right
    If i put 2 speakers on 1 channel it cuts watts in 1/2 so it started out as 1 speaker 220w for that channel now with 2 it will be 110w for ea speakers or dose it cut total in 1/2 and give 55w per speaker

    Frequency Response : 10 - 50 kHz (+0/-3 dB)
    Harmonic Distortion : 0.05% (at 1kHz)
    Impedance : 2-8 Ohms Stereo or 4-8 Ohms Mono
    Input Level : 0.3 - 6.0V (RCA input) or 1.2 - 12.0V (High Level Input)
    Low Boost : 0-10dB Variable (at 40Hz)
    Operation : 2/1 channel configuration
    Signal-to-Noise Ratio (dB) : 93 dBA
    Tone Control(s) : Low Pass Filter: 50-300Hz, 12dB/Oct Subsonic filter: 6-70Hz, 12dB/Oct

    You can run those speakers, with that amp, without any problem (2 speakers parallel per channel). This wouild yield 135w per speaker, which more than enough to power those 6x9s. Only thing that might be an issue is the amp thermalling, from heating up do to the 2 ohm load when you are running it hard.

    Hook it up how you described in your 1st post, it will be fine.

    Nearly impossible to find an amp that isn't 2 ohms stable in stereo now a days.

    Thanks for the reply I just got an email saying the same thing and that makes me fell good about it

    We plan on mounting the amp with plenty of room around it and put a fan blowing across it, plus it has its own fan in it.
