Just after people's opinions on what the best way to wire a DVC sub. First off would it be better to run the coils on a channel each on a two channel amp?? Or run the two coils of one bridged channel?? And what would be the best way to wire the subs if run on a single channel - with the coils in parallel or in series??

The best way to drive a sub is with a monoblock amp (hell...it's what they are designed for). Then you need to know the impedance of each of the voice coils on the sub, and the minimum impedance the amp can operate at.
For this example I will be supposing that you're working with two subs with two 4ohm voice coils a piece.
There are lots of ways you could wire it up, and you can wire it in between an impedance range from 1ohm all the way through to 16ohms.
If your amp is 1ohm stable, then wire the coils in parallel, and wire the subs in parallel. This will create a 1ohm load across the amp.
If it's 2ohm stable wire the coils in parallel and the subs to separate channels.
If it's 4ohm stable wire the coils in parallel and the subs in serial
If you don't know to which impedance the amp is stable wire it to 4ohms and you SHOULD be safe. |

What i have are 2x Pioneer GM-X952 amps which are a two channel amp and 2x Pioneer 12" 'Bullet' DVC subs and a stinger capacitor. I have the paper work for the amps but nothing with the subs. Load impedence is 4 ohms unbridged 2 - 8 ohms allowable with a bridged connection is 4 - 8 ohms allowable.
I have just now found out that they are dual 4 ohm voice coils. SO what do you reckon mouce?? |

First up, why bother with the capacitor? If you've got power supply issues a cap isn't going to 'fix' it, you either need a bigger battery, a second battery, better cables, or a bigger altenator. Caps are just a band-aid solution.
If you're just using it because you think it looks cool then by all means enjoy it.
As for the wiring. (without knowing the partnumber of the subs I'm just having a guess here), but each of the amps can run at 300W (bridged) into 4 ohms right. By the same token, it can run 150WRMSx2 into 2ohms.
The way I'd go about this personally (with the gear you've got) would be to wire the voice coils in parallel (on each sub) and have each sub wired to a separate channel on the same amp. Each sub would present a 2ohm load to the amp, you'd be getting 150WRMS through each sub, which is more than enough to hurt your ear drums. I'd sell the other amp and get a 4ch to drive the main speakers.
That said, there's a few options for how to wire them up.
Option 1: The one I just mentioned, using one amp to drive both subs, it'll do it comfortably.
Option 2: Wire the Voice coils in parallel, then wire each sub to a SINGLE channel on each amp. This will leave a channel on each amp un-used and is fairly pointless, but at least you'd be able to use both amps.
Option 3: Wire the coils in series and wire each sub to a bridged connection on each amp (one sub to an amp). You'd be running an 8ohm load, it'd sound clear as anything, but wouldn't be crazy loud.
Option 4: Wire each voice coil to its own channel on the amp. Again, one sub to an amp. I wouldn't recommend doing this though, because unless you can get the two channels playing EXACTLY the same thing (and I mean EXACTLY) you'll burn out your subs quicker than normal.
Unless you've got a very specific reason for wanting to run one sub per amp, I'd drive both subs off the one amp. As I mentioned first up.
Keep in mind that it's important to find out the power handling limits of your subs, no good wiring them up and throwing 300WRMS at them, only to find out they can only take 200WRMS. It'll smell really bad 
Don't be fooled by the advertising that claims it's a 600W 12" sub or any crud like that. Get the part number, and hit google and find out what the RMS power limit is.
Find me the WRMS power rating (it might even be on the sub itself) and then I can let you know the best way to wire it up out of the options above. |

On the sub itself it states 1000W Max and 500W Nominal. This site is about all I can find out about the sub http://www.pioneer.it/it/products/archive/TS-W1201DVC/index.html. I bought a complete custom install out of a VT-VX commy as it was cheap and came with the subs, amps and the cap as well as all stinger wiring and neons and such. The plan was to put it all into my other halfs car but she wouldn't be in on that. So i stripped the good bit and am in the process of selling the custom box and false floor. Very nice install i must say am in the process of something similar in the VN.

Okay then, 500W nom. is what I was looking for.
As far as I can tell Option 1 would be the easiest way to do it.
How were they wired in the other car? That could be a good spot to start.
Also, if you want the subs to sound a little more ballsy, then spin them around so that they fire into the boot. (have the cones facing the back of the car). Facing them forward is okay for show, facing them backwards tends to make it sound better. |

| No worries thank for the advice mouce. Will keep everyone posted on the install. Although there may not be much for a while as am about to move into a very big debt(rather small house in other words). |

| Then wire them up to the single amp and sell the other one off...any money is good money when you're paying off a house. |
