Why does my new 6.5" sub have two sets of connectors instead of one?

As the title really, my new Dual 4ohm Elemental Designs 6.5" subs have just arrived and they've got 2 sets of connectors going to them. Does this mean both sides have to be connected for the speaker to work? Or is it simply to keep the wires tidy allowing you to connect them to either side?

If that is the case, what does that mean with regard to amplifying them, will they just be connected as usual but with four wires from each channel instead of two?

It has those on both sides (12 oclock and 6 oclock)

That shows it better.
 
Ah fantastic, thanks for that mate.

So does anybody have any amp recommendations?
Is there any advantage over a mono, two or four channel amp to run these two subs?
 
I'll certainly let you know how they are once I figure out what amp I need to power them!

Here's where my head is at now:

I have 2x Dual 4Ohm, 250watt (each) subs.

That means the amplifier I get must be able to provide two channels of 250watt @ 4Ohms?

Looking online, I don't seem to be able to find any that can deliver that wattage for anything other than silly money.

Even the £200 Harmon Kardon will do: RMS Power @ 4Ohms : 2 x 110W

Am I barking totally up the wrong tree here, or do these tiny subs require a LOT of power?
 
Unfortunately a bigger sub isn't an option as they are going in an MR2.
They will be mounted in 7l sealed boxes and because the cabin of the car is so small I think these two will be quite sufficient.

Does anybody have any reccomendations of amps that would power these well in the £100-150 price bracket?

Ah just seen you have two subs?
So you would really need two of those amps... Or you could find an amp that was 1 ohm stable and wire all the voice coils from both subs into it. Ideally you give a sub as much power as it can take, but in reality, for most installs that amount of power is going to be overkill. If you get an amp that is 500W RMS into 1 Ohm I'm sure you'll be very happy with the results. :)

This will do the trick

That's too much over budget really, as i'll be getting front components plus another amp to power them - I don't really want to be spending £500 on an install.
 
Any other suggestions on amps that fit in to my budget and will drive these two subs? I'm seriously struggling to find one and this cash is burning a hole in my pocket!

Here are a couple of 2 channel amps, I know the 2nd is a little out of your budget but it can supply decent power. You'll probably be best running one set of cables to one voice coil on each sub and then having a short cable run from the 1st voice coil to the 2nd.

That'll show the amp a 2 ohm load on each channel.

Surely they still wont supply enough power given that my subs need a total of 500 watts (2x 250watts).

The Diamond one is:
# RMS @ 4 Ohm: 75 Watts x 2 = 150 Watts total
# RMS @ 2 Ohm: 125 Watts x 2 = 250 Watts total

and the SPL one is:
# RMS Power 4 Ohm: 2 x 100W = 200 Watts total
# RMS Power 2 Ohm: 2 x 160W = 320 Watts total
 
Yeah I asked them but didn't get much response at all.
It's a pain in the arse to be honest, I've got these two subs and boxes sat ready to go in to the car and nothing to power them!
 
Second hand isn't an issue really, I bought the amp for my last sub second hand and it's still going strong.
 
Out of the fusion and the pioneer, which would you go for?
Even though it's cheaper, I'm drawn towards pioneer over fusion purely because of the stigma attached to both companies.

Don't underspec an amp, you'll pay for it in the long run.

edit... £80 for two? They're £55 each aren't they? How'd you get them for that price?

Off ebay, can't remember the name but they were going for £40 each brand new boxed. It's a company too, not a private seller.

As a guide for myself really, how would you rate the JBL GTO amps, more specifically the 4 channel one (not to power my subs, but just so that I can gauge 'quality' vs my needs).

Are they regarded as good amps?

Well, there is that ;)

Funny you should mention a nice new pair of subs being driven hard... Adam, take it easy for the first few hours. You don't want to fudge the voice coils by driving them hard when they're tight. New speakers usually need a lot of playing time to loosen them up.

The thing is, I don't want these for bone shattering bass - they're just there to fill in where my components can't reach. I'm not looking for uberbass i'm looking for decent quality music to listen to at normal volume.
 
Fair enough, that's what I used to have to power my old components and 6x9's and was always happy with it. I was hoping you'd say it was **** so that I could convince myself that the pioneer one was a good choice!
 
Right, might have found a possible winner...

Looks like a good mix between money and performance and I've had this range of amps before and was always impressed.

Any nay-sayers before I hit buy?
