Help how do i connect 3 sub to my orian hcca 225 .ihave 1orian 10inch &2 cvr10 all dual voice coils

Is the amp a single channel? If so, the only way to connect the subs (without overloading the 2 ohm stable amp) is to wire each sub's voice coils in parallel (2 ohm) and then connecting the subs in series (4 ohms). If the amp is two channel, the subs can have their voice coils connected in parallel (as before) and then each sub connected to its own channel.

Here are 2 ways. A dual 4 ohm works the same but the ohms is double for mono output

You would need to know what power your amplifier supplies at 4 ohms. In reality, you would be better off bridging the amplifer and wiring your sub in parallel to a 2 ohm load. This would allow you to pull the most power out of the amplifier. It would be safe to do a voice coil to each channel on a 2 channel amp. However, if you happen to have a 4 voice coil sub and attempted to put two 2 channel amps to it, you would have to make sure your amps are leveled. No easy feat. The variance you could have with that could damage the voice coils. But luckily, that's not your case.

so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

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.

Hello brianmitchel,

From what I am able to determine, the Orion HCCA250 is a bridgeable 2-channel amp that is stable to 1ohm when bridged and outputs 800 watts RMS into that load.

The JL W6's in both 10" and 12" versions are dual voice coil with 4ohm coils so they can be wired to present either an 8ohm load (series) or a 2ohm load (parallel). They can handle 600 watts RMS.

With this combination, the best configuration would be to wire the sub voice coils in parallel for a 2ohm load and then parallel both subs to the amp bridged terminals for a final impedance of 1ohm. The subs will each be getting 400 watts.

In any event, I would not recommend running subs in series. There is some evidence for distortion being caused by something termed "back EMF".

Hope this helps.

Your speaker is a dual 2ohm sub. If you have both voice coils wired Parallel that will drop the ohm load to 1, which the amp can not handle. You need to wire the voice coils in series. Treat each voice coil as a speaker.

If you have one sub dual voice coil, just paralel the sub and conect to brigde amp. Simple...

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.
