The higher the impedance, the better sound quality the amp has. It's the lower ohm you have to worry about. Zero ohms is a dead short. 1 ohm isn't too far from it. 4 ohm is farther yet. The lower the ohm, the harder the amp has to work. parallel,all speakers positive terminals to the positive terminal of the amplifier and connecting all of the speaker negative terminals to the negative terminal of the amplifier. in this case Parallel wiring is connecting components to a source so that they share the same voltage

Ok I have 2 12" cerwin Vega dual voice coil woofers if they are 4 ohm dual coil each,,,each one is wired to 2 ohms,,,should I connect each woofer together to make them 1 ohm and put them on a mono amp or...


First you cannot run 2 dvc 4 ohms at 2 ohms its either 1 ohm or 4 ohm. and yes you should bridge them better performance and power. i have looked it up for you and this is your 2 options at running your subs.

Can i power 2 12 subs a rockford punch z and a xplode with this amp i found all this **** in my garage and i need to know if it will power all this


First of all. Using two different kinds of sub woofers, is not an option, as these two sub woofers have different specifications and you should never mix sub woofers. Now the better choice from the 2, would probably be the Rockford. (cant be sure without knowing the models, power handling is also a factor in how well either of the sub woofers will play, but Rockford as a rule makes better sub woofers than Sony does) In my opinion, both the sub woofers deserve a better amplifier than what Boss has to offer. However to connect either of these sub woofers, you would need to determine how many voice coils it has and how many OHM the voice coil/s are. If it is a DVC (dual voice coil) and each voice coil is 4 OHM or 2 OHM, then you can connect one voice coil to one channel of the amplifier and the other voice coil to the other channel of the amplifier. If it is a DVC 2OHM you can also connect it wired in Series/Series to give a 4OHM load and should be connected to the BRIDGE dedicated speaker outputs of your amplifier. If it is a SVC (single voice coil) and it is 4 OHM, then you can connect the sub woofer to the designated speaker outputs of your amplifier that states BRIDGE. DO NOT run the amplifier in BRIDGE mode at 2 OHM as this will probably damage the amplifier. dreamsystems

How do i install 2 ckicker cvr to my amp


Here are a couple of diagrams 2+4 ohm dual voice coil wiring.

Option 1 (parallel/parallel) = 1 ohm load
Voice coils wired in parallel, speakers wired in parallel
Recommended Amplifier: Stable at 1 ohm mono 2_4ohm_dvc_1ohm.gif
Option 2 (series/parallel) = 4 ohm load
Voice coils wired in series, speakers wired in parallel
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono 2_4ohm_dvc_4ohm.gif

Option 1 (parallel/parallel) = 0.5 ohm load

I cant sem to wire it to 4 ohms because the terminals are right next to each other and i have no clue which 1 is which voice coil?


test with a digital multimeter set to ohms. if you don't have one of those laying around grab a 9 volt battery and run wires from the 2 terminals on the battery to 2 of the terminals on the woofer. if the woofer pops out you are said to be "in phase" (even though it has more to do with polarity that phasing but regardless) which means the positive from the battery is on the positive of the woofer and the negative is to the negative. those 2 terminals on the woofer are a single coil and obviously the other 2 terminals are the 2nd coil. now depending on what impedance each coil is will determine how you have to wire it to be 4 ohms unless they are 4 ohm coils which means you just use one coil and it will be 4 ohms on that woofer.

I have 2 positives and 2 negatives on back of my alphasonik sub, do i connect amp to one side or both sides?


Hello gaz69,

Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.

This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.

Hope this helps.

One of the negative wires came of the coil? the woofer has 4spring loaded terminals? is it still good?


Your woofer has 4 terminals because it is a dual voice coil woofer. It has two electrically seperate coils wound together. This can be used two ways. If you have one woofer only and a two channel amp, each channel can be fed to its own voice coil on the woofer. The other way would be to wire them in parallel to get a 2 ohm impedance or in series to get an 8 ohm impedance or just use one coil to get a 4 ohm impedance. If the negative broke off of one the other should still be good. This would usually be 4 ohm for each coil. The other broken coil can be repaired but it would require removal of the surround and spider from the frame and if you have never done this before it isn't recommended you try it. If you are running a dual channel amp you may want to bridge it to one channel if you are to use one woofer with one coil only. If you have a pair of woofers, use one coil on the other as well since the loads(Ohms) should be equal to each other.

Subwoofer Dual voicecoil wiring


1 ohm will draw too much current.those are designed for a 2 channel 2 ohm drive for each sub.running 4 ohms will be easier on the amplifier and since impedance is not constant it may run 3 ohms at some frequencies anyway. another solution if your power amp is bridgeable....put the coils in series on each woofer making 4 ohms.then parallel the two 4 ohms to make 2 ohms and run the amp in bridge mode at 2 ohms.since bass is omnidirectional,you can do it

Hooking up a cvr10 woofer 2 ohm


run one red wire to red on one voice coil then black on opposing voice coil should leave you with one red and one black on opposing voice coils run a wire between the two that will give you 2 ohms impedance then from red on other voice coil to positive on box and from black to negative on box and from input on box run to amp same way + for + and - for -.

Hi yeahonda,

 

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

 

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

 

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".

 

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.
