    Wiring 6 channel amp to DVC sub

    I've been trying to research this but finding exactly my same setup and comparing the different options for wiring has left me still confused.

    I have a Precision Power 6600. Has 6 channels, front 4 are to main speakers and until now have bridged the rear two to power my single voice coil 10" sub. I am replacing that sub with a dual coil 12". My question is, do I run each channel to each coil? Bridge the amp and bridge the sub?

    Here are the specs for everything, I know that's what matters.

    Amp:
    50 RMS x 6 @ 4 Ohms per channel
    100 RMS x 6 @ 2 Ohms per channel
    200 RMS x 3 @ 4 Ohms bridged

    Subwoofer (Pioneer Champion):
    4 Ohm x 2

    And the manual for the sub shows some cryptic drawings I can't quite make sense of. Here's the PDF link from Pioneer.

    Thanks in advance for the help.

    Something you need to realize...

    If you run 2 4ohm subs in parallel they are a 2ohm load to the amplifier. Should be same for a DVC subwoofer when running the DVC in parallel.

    If you bridge an amplifier from 2 channels to 1 then a normal 4 ohm load is seen as a 2 ohm load on the amplifier.

    So if you bridge your amplifier and run your DVC in parallel the amplifier will see a 1 ohm load.

    If you check your amplifier specifications, most lose clarity when you drop the ohm rating from 4 to 2 and will likely not be rated for 1 ohm...

    Also especially with a DVC subwoofer the lower hz you can run on the top end the less cancellation you will get from running stereo leads to it. I used to run 60-85 hz as my top cut off on mine but I also had 6.5" sub woofers mounted in the front that I ran from 75hz to 150hz. You can try different things if you have an adjustable crossover. You will find the bass should be clearer and louder the lower the hz the top cut off is in most cases but then your woofers up front have to handle the range you are not running with the sub. So it can be a trade off...

    Ok, so I think I have a better understanding. And I also think I get the Pioneer drawings. Is the best option to bridge the amplifier to 4ohm and then run the sub as shown in the first picture? Looking at the bottom corner of the first setup, it's shows a matching 4ohm.

    I did a little more research and it looks like I jumped on the wrong subwoofer. A dual coil sub at 4 ohm per coil can be ran at 8 ohm or 2 ohm.

    I could run the dual coils in a series for a 2 ohm load and only use one channel of the available two. This works, however I'm sending only half the power (100w) to the sub. I either need to find a different sub or buy a mono amplifier that will get the full potential out of the subwoofer.

    I'll run it at low level to see how it sounds and if I'm not happy I will pursue one of the above options.

    Just run the DVC in stereo with one channel going to each voice coil and you will be fine. It will still be a boost in your output. No need to mess with bridging or combining the speakers.. Just run them like they were another set of speakers going in your doors...
