Series/Parallel wiring

[Moriartii]

Ok I have a dumb question here:

How do you wire a sub in series/parallel? I have found the diagrams and for some reason it isnt clicking for me. Throw me a bone here. This is on a DVC woofer (dual voice coil).

Depends on what ohms you need to match up to. I take it you mean the sub has four terminals?

[Moriartii]

Yes the sub has four terminals to match each voice coil that it has. I need to present a 4 ohm load to the amp so in my case it would be series (2 x 2ohm DVC).

I assume the - of one coil is wired to the + of the other and then the remaining - and + are wired to the amp?

Series would not be right to drop the ohms on a DVC sub. What is the ohm value for each coil?

edit: I read your post again, and It looks like you have 2ohm voice coils. Series will give you 4 not 1.

No, series is wrong. Series will double the Ohm load, you need to halve it. Wire the + terminal of the amp to the + of the first coil, then wire that to the + of the second coil. Do the same for the - side and you will be running at 1 Ohm.

[Darth Martel]

series + \/\/\/\/ - + \/\/\/\/ - (the middle - and + is wired together) series adds resistances


parallel
+ \/\/\/\/ -
+ \/\/\/\/ - (the end +'s are wired together and then the end -'s are wired together) parallel divides the resistances

[Moriartii]

See my original post, I had the load wrong. Needs to be a 4 ohm load, not the original 1ohm like I had stated.

So it sounds like I should wire it like Darth Martel suggests?

Yeah, just out of curiosity what amp and subs are you using?

[Moriartii]

Using a SSA ICON 12" sub with a SA 125.2 amp in a ******** trunk enclosure.

I would like to ask an add-on question for you guys.

When wiring up a sub, does the wattage the sub receives differ at all when put in series versus parallel?

I totally understand resistance, but I must have skipped the class in Physics about wattage.

I only ask because I was considering purchasing a new amp for a pair of subs in another vehicle, and I was trying to figure out what wattage of amp I needed to buy. I have two 4-Ohm dual-voice coil 12" Alpine Type-R subs. Which means, if I wire the voice coils in series but the subs in parallel, I get an equivalent load of 4-Ohms, or if I wire all four voice coils in parallel I would get an equivalent load of 1-Ohm. However, I am not sure what wattage I need to be able to push at the amp when the the subs say 500watts max per voice coil.

Does that make sense?

[Moriartii]

I think from what I have been reading you are ok to wire the subs voice coils in series but it is bad to wire the amps in series.

With the subs you have, a monoblock amp, rated 1000wrms at 1 ohm would be perfect. The Memphis MC-1000d is a good example.

[third1]

What type of sub is it( dual 2 ohm voice coil)or (dual 4 ohm voice coil) ? You will need a dual 2 ohm to get reach a 4ohm load.

This is a nice visual example of the different wiring configurations that someone put together http://slumz.boxden.com/f22/subwoofe...agrams-833961/
