Diagram to connect amp and sub to vm9311

Yes. This model has a dedicated zubwoofer output. Virtually any sub woofer amp that connects via RCA will work.

how you wire it depends on your amp, I assume that the sub is a 4ohm DVC from what you have provided.
Parallel:
If you have an amp that can handle a 2ohm stable load you can connect one voice coil + and - to the amp and then run wires across the sub to the other side + to + and - to -

Series:
If your amp won't support 2 ohm you have to run it at 8ohm, to do this you connect from the amp to one + and to the - on the other voice coil on the sub, you then run a single wire between the + and - terminals .

Below are some images to help

Parallel (2ohms)



Series:

You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.

Use good quality wires-- the cost is the factor for high connectivity with low resistance- You can bridge the two sub's in parallel to the 2 ohms output of the amp. Please be careful to see the likeness of polarity of the subs to the amp. or lese you will get a phase difference resulting in poor low frequncy.

No diagram but you can printthis out. Choose 1 set of inputs for the subs on the amp (I usually use the low or rear which ever has more settings) You need to put the settings to low hertz and no high settings. Now in the output side you're going to use the positive side of the right side speaker and the negative side of the left side speaker (you can switch left or right as long as they are opposite sides!). Lets start with the negative wire connect it to the negative input on one of the subs, connect the positive wire to the positive input on the OTHER sub, then get an extra wire to connect the inputs not used on both subs. Adjust settings in amp and radio and if it doesn't sound good use negative and positive outputs from one single output (only left or only right) Hope this helps

Hello solo7908,

With a single 4ohm DVC sub there are only two possible wiring solutions, parallel the voice coils for a final 2ohm load or series the voice coils for an 8ohm load. In your case, you want to wire them in parallel, both positives and both negatives connected to the amp terminals.

Here are the diagrams: (-) to (-) and then to the amp - (+) to (+) and then to the amp. Impedance = 2ohms.

Hope this helps.

wire the subs at 2 ohm each. red to red and black to black and then to the amp. if thay are a dual 4 ohm sub. dual 2 ohms will need to be wired red to black on one coil and the other conected to the amp.

dont need a diagram,, most amps have a speaker level input...dont mix this up with line level....connect your wires from back of factory speakers to speaker level input on amp...then if your amp has a low pass switch select lowpass setting now you have punch

The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.

you are mising to power on the factory amp.
