Re: 2 or 4 ohm Sub

i myself would buy the dual 2 ohm. break it down to one ohm, get all 500w to your sub...

Re: 2 or 4 ohm Sub

The amp runs it's peak 500W @ 2 ohms final load, so that's what you want. Get the 4 ohm DVC and wire it in parallel to get a 2 ohm final load, and therefore get the peak performance out of it and not destroy your amp in the process. That amp isn't stable at 1 ohm load.

As such:

DUAL 4 OHM! The first link you posted. SWR-1042D. TheGr8 is correct. The two voice coils will be wired as pictured, in parallel, for a final load of 2 ohms.

Re: 2 or 4 ohm Sub

ok just got that sub, 4ohm, now how do i physically hook this bad boy up?

Re: 2 or 4 ohm Sub

As such:

Follow this. The left positive and negative signs are to the amp, and the circle is the sub. Since it's a DVC, there are two +'s and two -'s on the sub, so follow the diagram.

Re: 2 or 4 ohm Sub

ok and then just use the jumpers to connect + and - to each other? And the + and - cable from the amp can just hook to either of those terminals?

Re: 2 or 4 ohm Sub

Don't really understand what your saying. The diagram should be more than enough to show you exactly what you need to do. The + and - on the top and bottom each represent a voice coil on the sub. They are grouped just like that on the speaker itself. The lines on the diagram are wires. Just take a look at the sub and the amp, it really is quite self explanatory.

Re: 2 or 4 ohm Sub

Pretty clear in that picture.

Connect all the positives together.... including the positive on the amp. Then connect all the negatives together.... including the negative on the amp.

Re: 2 or 4 ohm Sub

first off u need to find out if ur amp is 2 ohm stable if so that is the better speaker but check your amp first

The link that states the amp does 500WRMSx1@2ohms is what tipped me off...

Re: 2 or 4 ohm Sub
