Hello fla2ga1008,

To wire the D2 voice coils for 4ohms, you simply jumper the positive side of one coil to the negative side of the other coil (series). Connect the remaining terminals to the amp for a 4ohm load.

If you wire both positives and both negatives together and then to the amp terminals (parallel), the impedance seen by the amp is 1ohm.

Hope this helps.

How do I hook up my adiobahn immortal awis12p quad coil in parallel and in series


Parallel would be + to + and - to -. The end result is that the ohms of each voice coil add together. So 4ohm+4ohm+4ohm+4ohm would be 16 ohm final load. Series is +to -. And the ohms drops. With 4 voice coils you have alot of choices as to how to wire it..all of which is determined by the amplifier you are using.

How do I wire up my 4subs in bridged to my peace 2600


Hi,

Please state the subs impedance, but assuming 4 subs with 8Ohm Voice Coil you CAN'T run them in parallel in Bridge Mono because this amp's minimum impedance is 4Ohm in bridge and 2Ohm stereo, maybe a series/parallel connection work, but what's the advantage to run them in Bridge mode? This amp delivers 900W per channel at 4Ohm, you can run a pair paralleled for each channel in a safe way and without the high-risk of your amp being destroyed, besides, amp power at 4Ohm Bridged is NOT recommended for continuous use, let me know your results...

Hi, I want to know what is the best way to wire these subs. (Pair). I have heard of several ways. I have a 4 channel amp the soundstream picasso 4.760. Bridged it produces the most power. I was told...


Hello , I will be glad to help you.As far as your speakers..It depends on what impedance your subs are rated and if your Picasso amp can be bridged at 4ohm or 8ohm. If your subs are 8ohm each you can wire your subs in parallel and wire them to picasso amp in bridged mode. If your subs are 4ohm each.Then wire the subs in series then wire them to amp in bridged mode..caution do not wire subs in parallel if they are 4ohm .This would bring impedance to about 2 ohms and would be harsh for amp to handle...Goodluck

How do i bridge 2-4ohm dvc's to a mono block


If you have a DVC 4ohm speaker, and you are using both voice coils, the amp is seeing a 2ohm load.
If you bridge the amp, you CAN run both subs as long as the amp is Two Ohms Stable.
Wire each subs voice coils in parallel.(Positive to positve, neg to neg.) (2ohms) each.
Then wire the two subs in series.(Neg from amp to neg of sub one, pos of sub one to neg of sub two. then pos of sub two to pos of amp.

If it sounds too hard, leave it as you are already running the amp at two ohms.

DONT KNOW HOW TO RUN 2 OHMS


Hello storres18,

If you have the Kicker model number 06CVX122, with dual 2ohm voice coils, they can be connected to a mono amp at 2ohms. First jumper the voice coils in series, the dotted positive (+) to the undotted negative (-) (or vice versa). Each sub is now 4ohms. Then wire both of the remaining positives and negatives together on the amp terminals (in parallel). The amp sees a 2ohm load. Here's the diagram:

If you have the Kicker model number 06CVX124 with dual 4ohm voice coils, they cannot be wired to present a 2ohm load. They can only be wired as a 1ohm load (too low for the amp) or as a 4ohm load (at reduced power). Here is the diagram of the 4ohm wiring:

CORRECT CONNECTION TO AMP BEING A FOUR TERMINAL SPEAKER


Hello i_starling,

The Kicker L7's come in either 2ohm or 4ohm dual voice coil (DVC) versions.

Whatever amp they are connected to, you need to know both the impedance of your L7's and the impedance of your amp. The L7's dual voice coils can be wired to provide a total of four different loads:

2ohm coils in parallel = 1ohm load
2ohm coils in series = 4ohm load
4ohm coils in parallel = 2ohm load
4ohm coils in series = 8ohm load

Your best connection would be the one that results in a final impedance load that is supported by the amp.

Hope this helps.

I want to know how to wire a speaker


Weather of not you can use this speaker as an extension cab depends on a number of things. First, what amp are you planning you use for it? What is the minimum resistance for this amp (2ohm or 4 ohm probably). Second, what is the primary cab you are using ans what is the resistance on that? (2ohm, 4ohm or 8ohm).

Is there just one speaker in you proposed extension cab? The goal is to have all the speakers wired in parallel without lowering the resistance to a point that will damage the head. So if your amps minimum resistance is 4ohm then your cabs will have to both be 8ohm, running in parallel the overall resistance will be 4ohm.

Help on 1 amp and 1 alpine srw-124d


You have dual 4-ohm coils. 2 coils per speaker.using one speaker, if you take and run the postive from one coil and connect it to the negative of the other coil, then take a wire from your bridge channel on your amp and connect the positive to the the remaining positive on the one coil and connect the negative to the remaining negative on the other coil you will create a 8ohm load on the amp in bridged mode.

now this is the important part. The bigger the load on the amp the greater the wattage output to the speakers. This sucks the wattage out of the amp. Careful not to overload you amp. The setup above is safe for any amp. The following is for 2ohm stable amps only. The lower the ohm value 2, 4, 8 and so on, the greater the load on the amp.

connect the positive of one coil to the positive of the other. connect the negative of one coil to the other negative of the other coil. then take a wire from your bridge channel on your amp and connect the positive to the the positive on one coil and connect the negative to the negative on the same coil and you will create a 2ohm load on the amp in bridged mode.

Series = add the two ohm value
parallel= halve the ohm value

you can play with series and parallel together using more than one speaker setup.

Wiring


The T10001 can drive a load lower than 4 ohms. Wire the coils of the individual speakers in series to make each speaker 8 ohms. Then wire all 3 speakers in parallel and connect them to the amp. This will give you a 2.6 ohm load.
