Wiring Question

[duketter]

I have 2 DVC subs that are each 4 ohms. I have them connected with voice coils in series/parallel. My question is this....I have 2 wires running to the positive in my amp and 2 wires running to the negative in my amp, instead of splicing into the wires and just running one positive and one negative to the amp.

Does this make a difference on how my ohms the amp sees? I sure hope I explained it good enough?

Maybe to clarify some things this is how they are wired now. On one DVC sub I have the negative hooked up the the positive. Then I have the other positive hooked up to the amp's postive and the other negative hooked up to the amp's negative. The other sub is just the same. So instead should I connect those "other" positive and negatives to each of the other subs and then splice one wire to the amp to connect them both to the amp?

I am trying to get a 4 ohm load to the amp and my current setup might be showing it 8???

Do you have them wired in series or parallel??? They're not the same...

Sorry, here is how I have them wired up.

http://www.jlaudio.com/tutorials/wiring/index.html#2dvcsp

Go to 2 DVC drivers with Voice Coils in Series / Parallel in the links on that page. So it is both???

But instead of having just one wire to the amp like in the picture to the neg. and pos. I have a total of 4 wires going to the amp.

I can send an email of a picture of how I have it wired to someone and they can maybe post it? I cannot post attachments?

i think what hes saying is that he has the actual dual coils of each sub wired in series. but he is running each speaker independantly from the amp.

is this a two channel amp where you are connecting the two speakers as a seperate channel?

if each coil within the DVC subs are 4 ohms, then each channel is seeing 8 ohms since they are in series.

I have it bridged to a 2 channel amp. I have 2 wires running to one pos. on the amp and 2 wires running to one neg. on the amp so it is bridged.

I can send a pic to someone if that helps?

do you have a 2 channel amp or a mono amp? are the two positives going to the amp connected to one terminal or do you have them on seperate channels? what is your question again?

yea send me a pic:

james.fitzgerald@villanova.edu

i can post it for you

so it is a 4channel bridged to a 2channel or a 2channel originally bridged to a mono?

"do you have a 2 channel amp or a mono amp? are the two positives going to the amp connected to one terminal or do you have them on seperate channels? what is your question again?"

It is a 2 channel amp, a MTX 2150x amp. The 2 pos. going to the amp are connected to one terminal, same with the 2 neg., they are connected to one terminal.

this is the same as the website. your just using longer wires.

It makes no difference. Basically think of it as you are splicinf the wires together at the channel connections and the single wire is in the amp going to the power source.

Each voice coil is recieving 4 ohms. The dual voice coils in each sub are in series, so the ohms stay the same for each one. The two subs are in parallel, so they share the ohms(4 ohms to each sub/adds up to 8 ohms. I hope this info helps.
