Wiring 2ohm dual voice coil 15’s

I recently wired 2 2ohm dual voice coil Kicker Comp VR15's to my 2400watt RF 801s(2-channel) amp. I know they need to be wired in series and I thought they were, but it still sounds wrong at high volumes like when I had them wired in paralell(which one at time is exactly what the 15's are capable of and what I expected them both to sound like now). So this is how I have them wired.

Left Sub: one negative post to a positive, the other positive to the left channel positive on the amp, the other negative to a positve on the right sub

Right Sub: one negative to a positve, the other negative to the right channel negative on the amp, the other positive to a negative on the left sub

Anybody tell me what I'm doing wrong? Any help is appreciated, Thanks

You have a 8 ohm load bridged onto the amp.  You can't make 4 ohm total with this model so that is what you have to deal with.  (The amp wouldn't handle a 2 ohm bridged load.)  You just might have the amp at clipping level to get the output you're trying for...and it is showing in the sound.

So you should wire them like this:

but the RF 801S amplifier does not support a 2ohm load bridged.  I had one last year and it kept turning off (protect mode b/c of overheating). So you can run just one speaker with this amplifier to see how it sounds like this:

This will give you a 800watt RMS x 1 bridged.  You can buy another 801S later on if you don't feel like it's enough db. These are 2 x 2ohm not 2 x 4ohm subs right.  What's the total RMS of each speaker?

You can't make 4 ohm total with this model

...as I posted above.  You might want to look at it again, or for the first time.  And when specs show a bridged rating at 4 ohms, and don't show a bridged rating at 2 ohms.....that means there is no rating at 2 ohms bridged......which you take as meaning you can't put a bridged 2 ohm load on the amp.

So you should just use one speaker and buy another amp later for the other one.

There is no efficient way you can produce a 4ohm load with all 4 voice coils connected.

Does anyone know if you can just connect one voice coil on each speaker?  If you can then you can bridge one voice coil on each speaker in series with the other for a 4 ohm load.  You would be using 2 speakers but I'm not sure how fast your voice coils would burn out or if there's enough excursion of the speakers.

Can you list the specs of your speakers next time you post.

So if you bridge them only using one voice coil your speakers RMS would be 100-500w and the amp's RMS would be 800w, so there's a greater chance you might overheat them.

If you get 200w from your amp at 4 ohm and the speakers is 100-500w then it should sound ok but the excursion will not be that great.  I'm just learning here so I might have given alot of bs ideas.

well, you can always buy two more subs and use them isobarically.......but that's not too pratical.....

There really is no good solution for you, other than to wire up the subs for two ohms, and then wire each sub to one channel.

or am I misinterpreting the diagrams?

Yes, that's what it is.  These diagrams are shown like that to make everything neat and tidy, and all the lines will be straight.  In real life it would look more like the following, one that I drew:

The wiring is series/parallel, in that the coils of each sub are in series and the subs themselves are in parallel (as in option 2 in the above linked diagram).  Connection to the amp is normally shown without detail, because in some cases:

• both subs will be connected to one channel, or
• the load is bridged to a two-channel amp, or
• the load is connected to a mono amp, and the amp might have dual terminals.

You would use the terminals on your amp that is proper for your situation.  In your case you would use the bridged wiring diagram shown on your amp, or in your amp's manual, which should be left channel positive and right channel negative terminals.

Please show me where I said that.  Keep in mind you're now talking about using DVC 4ohm subs instead of the subs you first asked about.

800 W X 1 @ 4 Ohms Bridged RMS

This is the bridged spec that you posted.  Isn't that the same as 400 watts per channel?

And you're welcome.

With the speakers you have there is no way you can wire them so they give you 400watts per channel.  You have to have them wired as 4ohms to each channel which will give you 200watts to each channel.  Your set-up could be compared to mine; I have two speakers which are at 4ohms.  When I had that amp I was only able to wire each sub to each channel which gave me 200watts RMS.  This was enough to feel some good bass from my system.  I upgraded to the 2004 model and a new box so now I feel like it's too much bass at times.

Just connect each speaker to each channel like this:

Try it to see how it sounds.  I think it will sound good depending on you box.

You mean to buy the 4ohm version instead of the 2ohm version? 

With the 2004 model (P8002)  that's what I'm planning on doing.  Getting a pair of P3 DVC 4ohm subs which RMS 500 each.  I'll only be supplying 800w but I think it will sound good.
