wiring a 2 ch amp to 4 ohm dvc

Hello- I see that this topic has been covered before, but I just want to make sure I grasp the idea before ruining something. I have a 2-Channel Amp: 4 Ohm: 100Wx2 2 Ohm: 200WX2 4 Ohm Bridged: 400Wx1 and a Sub: 450W RMS 4 Ohm DVC Since I cannot use the mono output of the amp (only able to achieve a 2 or 8 Ohm load due to the DVC config, right?), would it be possible to run both channels to the Sub in parallel without a problem? That is, connecting both amp channel's positive leads to voice coil #1 positive and both negative leads to voice coil #2 negative. Does this effectively throw 400W at the speaker? If this is not advisable, am I stuck with 8-Ohm with my current setup? Thanks for the help! -Tim

No, that will damage your amp.  Either use 8-ohms bridged or connect each VC to its own output channel (which is the same net effect, operating at the stereo 4-ohm rating.)Support the12volt.com

Thanks man. I appreciate the feedback. So, by damaging my amp, do you mean that my suggested wiring would have effectively made the amp see a 2-Ohm load, similar to wiring the mono output in parallel? Or am I off the mark. By wiring it as you suggested, does that mean that I bridge the channels, which would mean 400W at 4-Ohms, but then wire it in series to reach 8-Ohms and 200W to the speaker? -Tim

No, wiring it as you suggested would short out the amplifier channels and blow the fuses (at best) or fry the amp (at worst.)

Correct.
