What load is my amp seeing?

same drawing as that but a 1500d directed amp in 2 different boxes

are they getting a 4 ohm load or 1 ohm anybody?

Boxes doesn't matter. Actual routing of the wire doesn't matter. What matters:

1)The positive of one coil is connected to the negative of the other coil on each sub.

2)The other positive terminal and negative terminal are connected to their respective terminal on the amp.

It doesn't matter if the wires from one sub are run to the other and then to the amp. It doesn't matter that both are connected to the amps two terminals that are connected in parallel internally. The result of what I described above is a 4 ohm load assuming that both subs are dual coil 4 ohm subs.

so thats like saying you have to get 1222 and wire them at 1 ohm instead of 1242 on a 4 ohm? i thought i had a 1 ohm load?

Do you have any idea what you are talking about? I sure have no idea what you are going on about. If you don't understand the difference between series and parallel wiring and the effect that each has on the final load then you probably need to learn.

As for your last post, it is physically impossible to wire 2 DVC 2ohm subs to a 1 ohm load. It would seem that you are trying to wire 2 4 ohm DVC subs to a 1 ohm load. If you have them wired lik the drawing posted earlier in this post or like the drawing second on the left in the JL tutorial, then you have them wired for a 4 ohm load. If you want 1 ohm, connect all the positive terminals (both coils of both subs) to a positive amp terminal and do the same on the negative side. That will give you a 1 ohm load.

This is the best site I've seen for wiring questions. http://www.rockfordfosgate.com/rftech/wiringwizard.asp?WoofQty=2+woofers&WoofImp=Dual+Voice+Coil+-+4+ohms+x+2 If you have a mono amp like the tantrum 1200.1 the reason it has 2 sets of terminals on the amp is strictly for ease of wiring. they are parallel. your amp will see the same thing if you wire it like the picture or if you wire each woofer individually and bring them back to seperate terminals on the amp.
