You need a Cross-Over network for each speaker.

2 ohm amp to 2 10 inch dual coil 4 ohm subs how does it need to be wired


Is the amp a single channel? If so, the only way to connect the subs (without overloading the 2 ohm stable amp) is to wire each sub's voice coils in parallel (2 ohm) and then connecting the subs in series (4 ohms). If the amp is two channel, the subs can have their voice coils connected in parallel (as before) and then each sub connected to its own channel.

My type r sub has no sound on one coil but if i hook it up to the other coil it has sound and if i hook it up how its supposed to be hooked up it has no sound. What could it be???


hi,
You have to buy a new one because its coil has been burned. If you use tha woofer with the working coil then it can damage the amp. So try to buy a new one.
OK

I have an alpine cda9831 unit with 10" subs. I have an alpine v power m500 independently running them. The subs will randomly cut off and on and the wires to the head unit have been checked for loose...


so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

I have 2 15 compvr how do u hook the 2-&da2+ in da back of the speakers.


it depends on the amp your using and the impedence of the coils.(ohms) for general purposes lets say that you amp is designed to run 500 watts bridged mono into a 4 ohm load. Lets also say that your subs have dual 4 ohm coils on them. To achieve the 4 ohm load you would want to run the coils in series on each sub,meaning that one of the positives is going to connect to the negative on the sub the remaining + and - terminals are what you will connect your speaker wire to. you just turned your dual 4 ohm coil sub into a 8 ohm single coil speaker. Do the same thing to the other sub and now you have a pair of 8 ohm subs with a set of wires coming from each. Now parallel those sets of wires together( + and +) and (- and -) and run that to your amp. This will give you a 4 0hm load at the amp

How to connect HIFONICS BXI 2607 D watt at 1 ohm....


That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

Speaker or amp?


your running too low impedence, and yes its cuz of your sub wiring. How to wire it depends if its 2ohm dual voice coil, or 4ohm dual voice coil, so i'll explain both. O.K. first of all i hope its 4 ohm so you can get max power from your sub. If it is 4 ohm dual voice coil connect + to +, and - to - on your speaker, then to connect it to your amp, splice a wire into the wire running from + to + and connect it to your amp's + terminal. Do the same with your - wire. If its a 2 ohm dual voice coil, connect the + from one set of terminals on the speaker, to the - on the other terminal. Then to connect it to the amp, plug a wire from the open + terminal on the speaker and connect it to the + plug on the amp, and do, connect the empty - to the - on the amp. Good luck and if you have any questions don't hesitate to ask...

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.

Alpine mrd m500 amp is not pushing my 12 in infinity sub


If you have a dual voice coil sub, make sure that you have the positive and negative terminals connected properly. If you have ONE of the coils wired backwards, it will cause the speaker to produce little or no sound.

Have you set the gains properly?

Are you sure the amplifier is receiving a strong signal from the head unit?

Have you tried it with a different speaker?

*amp to sub wiring help...


The 2500D has 2 "+" and 2 "-" power connections to help split the current between two smaller wires vs. one giant, hard to route wire. According the manual, for optimal performance, both "+" and "-" power connections should be utilized. They also recommend using 4AWG wire for these connections.

The 2 "+" and "-" speakers connections are only there to simplify the wiring of multiple speakers into the amp. Both "+" get tied together inside the amp, as do both "-" connections. In this case, with the dual 2 ohm voice coils on your 12" sub, you would wire one voice coil to one +/- set on the amp and the other voice coil to the other +/- set.
