parallel and series question

[myjaja 10+ year member]

Why is it that you can wire two dual voice coil subs in series and parallel them at the amp but cant parallel the coils and then series both subs at the amp? I know the correct way is to actually series or parallel the coils at the sub but I was just wondering why you cant series them at the amp?

huh? bro... your wording... just, cant understand it

lol sorry.. ill try rewording it. Say I have two 12" subs that are dual 1 ohm each. Say I paralleled them each so theyre .5 ohm. Why cant I series the subs at the amp(after each sub is paralleled at the coil) so its at 1 ohm instead of .25 ohm. I was just wondering why it wouldnt work.

you mean running them parallel/series at the same time?

I believe it's just generally easier to wire coils on the same sub in series than it is to wire two subs in series, but coils are coils and I don't see any reason you couldn't do it either way.

yeah, pretty much

series/parallel on 2 1ohm dvc subs will put you at 1 ohm

Really? So itll work either way? Then I wonder why everyone was telling me it wont work that way. I even had my two 12" subs wired parallel at the coils and had them wired series at the amp with a final load at 1 ohm. My amp even went into protect until I rewired it. Now its final load is at .25 ohm with them being parallel at the coils and parallel at the amp. I dont really feel like taking my subs out to rewire them. Its was extremely hard to mount 61 pound subs by hand in the first place. lol

Maybe they know something I don't? From an electrical standpoint, I don't see how it would be different.

I think you need to show just how you are wiring these. and you should measure at the amp to make sure the load is where you want.

oh okay, and i wasnt being sarcastic btw.. I really dont know why it wouldnt work. So ill take your word for it. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

you could. but you'd end up wiring the subs in series either way. the amp only has outputs, not wires to switch up.

It's also technically easier to wire the subs in series then parallel at the amp since most mono amps will have 2 sets of inputs to make wiring 2 subs a lot easier.

No, I know, I seriously meant that they could know something that I don't //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The way that diagram is showing, I am pretty sure you have at least 1 of the coils out of phase with the other.... Somebody correct me if I'm wrong. (+ going to - on the right sub).

Either way, what does your ohm meter read at your amp? It should be around 0.8ohm or so for a 1 ohm final load and pretty close to 0.25 if you are really driving it that low in parallel/parallel wiring.
