I have 2 dual voice coil subs and there are four connectors on one side of the sub 1 2 -1-2 how to determine wich ones go together

sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

run them straight and dont use the cross over. One speak on right channel and the other on other channel. Then turn up amp settings 7/8 the way up and control the rest from your dvd/cd player. I recommend some monster cable which is very thick. Ground the amp directly to trunk bolts but make sure to scrape the paint off or the connection will be bad. You can also use a cap which will send battery pulses to amp much quicker.

Hello gaz69,

Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.

This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.

Hope this helps.

Well, this means you have dual voice coil subs. These subs are for running one sub in stereo mode( meaning you can hook up a right and a left channel to one speaker). In your case you are using 2 subs, which all you have to do is run a jumper wire from one side of the sub to the other. Take your (+) and hook it up on the (+)on one side of the sub and take your (-) and hook it up on the (-) on the other side and run a wire from the remaining post to the other. And do the same thing on the other sub.

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

If the subs are dual 2 ohm voice coils.....

1. For a each sub, connect one of the "+" terminals on the sub to one of the "-" terminals. This makes each sub 4 ohms.
   
2. Connect the unused "+" terminals of each sub together. Do the same with the unused "-" sub terminals. This makes the sub combination 2 ohms.
   
3. Then connect the "+" and "-" sub terminals from the above step to the amp.

If the subs are dual 4 ohm voice coils, you can't connect both subs in any fashion to get a 2 ohm impedance. The best you can do is make a single sub 2 ohms by connecting both "+" terminals together and both "-" terminals together or the pair of subs 4 ohms by doing the same, then connecting one sub's "+" terminals to the other sub's "-" terminals, then connecting the other "+" and "-" terminals to the amp.

Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.

What subs do you have? Is this amp 1 ohm ono stable?

First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.

It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.

The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.

Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

Mamola,

Get an amp with at least 200 Watts RMS. The RMS value is what is important about driving Subs. This could be proclaimed to be a 1000 Watt amp. REad the RMS value.

Wiring. It is better to series your Speakers to give them and your amp more reliability,

Get a Mono or Bridgeable amp. If it si bridgeable, BRidge the output as described in the manual you get. Some Amps have a diagram right on the output..

AMP+ to Sub1 +
Sub1 - to Sub2 +
Sub2 - to Amp -

Get a 4 Guage wring kit. Run your power wiring down the Drivers side, and Audio signal wiring down the Passenger side, keep the two separate.
