    Subwoofer Wiring

    I have a 5 channel pyle amplifier (4 X 250, 400 X 1). The amp is not 2 ohm stable but I wish to hook up two subwoofers to the 400 X 1 Channel. I believe my only alternative is to hook up two (8 ohm) subs wired so the amp see's a 4 ohm load. In this mode I am assuming my subs would see a max RMS of 200 watts per speaker. Are there any other alternatives?

    Thanks,



    Rod

    Well, if you are using the other channels for other speakers that is your only option. Although, you could get 2 dual 4-ohm subs, wire each one in series, then bridge them to the amp.

    Is there any difference in power to the amps if I wire them in series and bridge them to the amp vs getting to 8 ohm woofers?

    Thanks,

    No, if you wire a dual 4-ohm sub in series it becomes an 8-ohm subwoofer. So if you hook up two dual 4-ohm subs each wired in series then bridge it to the amp it'll be a 4-ohm load.

    Correct with 4 ohm load. 1/(1/4+1/4) + 1/(1/4+1/4) = 2/(1/2) = 4 ohms

    Remember, series = resistance adds, parallel = resistance adds inversely.

    Are the Type-S's DVC 2 or 4 ohm? Is the amp bridgeable?

    Nevermind, looked for it myself.

    Get the DVC 4 ohm Type-S's, wire them in parallel/series for a 4 ohm load, and bridge the amp into one channel.

    Wire the subs like so for a 4 ohm load-

    thanks for the help, but just one more question.
    im gonna get a new amp for the subs(200watt rms).
    and i just needed tod know if i got a 400 watt rms amp, would it push 400 watt rms into each sub, or 200 watt rms into 2 subs.
    assuming i wire them up bridged and parallel at 4 ohms, which is what the subs are.
    thanks
