need help with amp

You can wire it at 2 ohms if you only wire up to one voice coil. It is not possible to wire them both into 2 ohms. The diagram you posted shows them both wired so the result is a 4 ohm load. This is not what you said you wanted originally hence DevL's confusion.

 

The reason is because of ohm's law. You can wire in parallel or you can wire in series. With a dual voice coil subwoofer that are both at 2 ohms you can wire positive negative or positive to positive. This will result in a resistance of 1 ohm or 4 ohms. It's just math please learn ohm's law. Is the most basic electrical knowledge you need.

 

ok this helps a bit i think i had just had a typo somewhere and every one got confused

im sorry for the confusion i know what to do now. I just had a typo in my first post and it was all down hill from there.

 

DevL is absolutely correct on dvc subs you cant use just one set of connectors it will work but you will destory your sub quick. to get the most potential out of your sub you need an amp that is 1 ohm stable at 600 watts rms (continous) best to save and get the right stuff the first time because you'll end up in the same boat (no bass)

 

I don't know why you are not getting a class D mono block. If all you're are powering is the sub then get a mono block, buying a stereo amp for your sub is like buying a computer with a floppy disk drive. It's old technology for bass.

For a good amp on a budget look at something along these lines:

Hifonics HFi1000 Hfi Series D-Class Mono Amplifier 1 x 475 @ 4 OHMS, 1 x 750 @ 2 OHMS, 1 x 1000 @ 1 OHM

Then wire up your sub in series so you don't blow your speaker.

You will not destroy your sub by only using one voice coil.

 

thanks for all the info guys...im still searchin around but im shur ill come across somethin usefull

 

On an earlier post I suggested, "Then run the first amp with each channel of the amp driving one of the two voice coils on the sub. If you're using a sub out RCA from the headunit, you will need an RCA splitter into the amp, then just wire each side up to a voice coil as if it was two speakers in one."

Both of the amps listed (since they claim 2-Ohm stereo stable) will work. If you're using a single out line from the headunit (a subwoofer output) to the amp all you need is a RCA "Y" cable (splitter) to feed both left and right channels. If you're using a stereo signal from the headunit (like rear channel) to drive the amp, then you're good as is.

Now just hook one voice coil up to the left channel of the amp, and the other voice coil to the right side of the amp. It's not rocket science here (and I feel confident in that since I support Rocket launches from Cape Canaveral).

 

I have accually found a amp that better fits the bill i believe.......

1-Ohm stable does fit the bill.

 

That amp works, but make sure to wire it up with 8-gauge power and ground so that you blow your inline fuse long before you blow your speaker. If you wire it in parallel and run it at 1200 watts all the time, I would be surprised if your sub lasts a month.

Personally, for the same amount of money I would get this:

Orion ZT2000.1D ZTREET Series 1-Channel 2000W Max Class D Monoblock 1-OHM Stable Car Audio Amplifier with Remote Bass Knob/Free ALPHASONIK Earbuds

http://www.amazon.com/Kenwood-Kac-9...5?s=electronics&ie=UTF8&qid=1304994118&sr=1-5, and wire up your sub in series (that will give you 4ohms of resistance). That should be plenty of power for that sub.
