I have 2 subs that are 4 ohm svc and a amp that is 4 ohm 2 ohm and 1 ohm stable can I run my speakers down to 2 ohms or will it be bad for the speakers


remember dropping ohm load decreases resistance.The 12volt.com is a GREAT source for wiring issues,GOOD LUCK

Can i run a 4ohm.dvc & a 3ohm.svc off of a mtx te 801d


if you wire the 4 ohm sub voice coils in parallel you will have a 2 ohm load for the Image Dynamics sub, the JL sub only being single voice coil will of course be 3 ohm.
You cannot connect them both to the amp you specified as when connected the total load will be less than 2ohms and the amp will either trip it's protection circuit or could damage the amp, My suggestion is to try each sub separately and decide on the one you like the most or obtain a matching pair for the 4ohm DVC.

What way should I hook 2 12" jl audio to a jl audio 1000/1


Is this sub an svc or a dvc? From what I looked up they are svc, so each sub's voicecoil is 3 OHMS, connecting them in parallel would lower them to 1.5, and your amp is capable of going down to 1.5 ohms. So I would suggest running them in parallel.

Speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono 2_4ohm_svc_2ohm.gif
(Although from the information I gathered these subs have 3 OHM voicecoils, so in the diagram where is says 4 OHM it should say 3 OHM, and the 2 OHM should say 1.5 OHMS.

This is a good site to help calculate OHMS: http://www.bcae1.com/spkrmlti.htm


Hope this helps.

I have a amp with switch that says high power & high current


The ohms rating measures the electrical resistance of the subs(impedance). On the subs there is usually a label that tells you what the impedance is for that particular sub,example= 4 ohms . The only way you can get to a 1 ohm load or less with a pair of tens is if each sub has dual voice coils that are 4 ohms each wired in parallel. Generally Sony xplod's are a single coil 4 ohm woofer-yours might be the exception in this case .To figure out your resistance say with 2 subs that are 4 ohms you have to know how you intend to wire them for instance if your amp puts out a fair amount of power @2 ohms and thats the number you want to hit than you will want to wire the subs in parallel( + to + and - to -) wiring in parallel lowers the resistance.(ohms) If you want to hit 1 ohm and you have dual 4 ohm coils then wire all 4 coils in parallel and that will then be a 1 ohm load. Its simply a matter of dividing the ohms by the number of speakers that you intend to connect. if you had 3 10s that were 4 ohms each and you wired them in parallel the ohms would be 1.33 (as 4 divided by 3 is 1.33)(4 divided by 2 is 2) (4 divided by 4 is 1) On the flip side wiring in series will raise your impedance-a pair of 4 ohm subs wired in series gives you an 8 ohm load 3 subs gives you 12 ohms and so on. I wouldnt worry about the high current switch unless youre planning on taking it down below 1 ohm which it sounds like you arent currently set up for.

if u have the amp bridged un bridge it. chack an see wat the ohms are on the subs an make sure the amp is stable to carry the ohm load..if u have 4ohm subs one sub per channel then u shud be fine that wud make the amp see 4ohms but if u have dual voice coil subs it cud be the configuration of the subs..here's a link on how to wire subs hope this help..http://mobile.jlaudio.com/support_pages.php?page_id=145

I have a Kicker 2500.1 monoblock amp. I am going to run 4 15 inch Kicker L5 subs to this one amp. What ohm subs do I need to purchase? Dual 2 ohm, or dual 4 ohm? Also, how would I wire these subs to pull a...


make sure that you get dual 2 ohm subs. to get a 1 ohm load, wire each sub in a series. that means the positive from one coil, connected to the negative of the opposite coil. then the other two leads will be your active speaker wires. that will give you a 4 ohm load for each sub. once all 4 are wired like this, you simply take all of the positive wires that you have left, and combine them at the amp. do the same with all of the negative wires. that will give you 1 ohm. just be extra careful to make sure every sub is wired exactly the same, otherwise your sound quality will be greatly reduced.
also, 2500 watts isnt as much power as these subs will take if wired together. it will still sound awesome, but I reccommend turning the level on your amp up just until you hear a bit of distortion, then back it off a hair. being slightly underpowered will cause you to have some distortion in your bass. playing distorted notes builds up alot of heat in the voice coils, and these subs are VERY sensitive to overheating.

I need to know how to bridge a a 4 ohm 15 inch sub down to1or2ohm


Hello solo7908,

With a single 4ohm DVC sub there are only two possible wiring solutions, parallel the voice coils for a final 2ohm load or series the voice coils for an 8ohm load. In your case, you want to wire them in parallel, both positives and both negatives connected to the amp terminals.

Here are the diagrams: (-) to (-) and then to the amp - (+) to (+) and then to the amp. Impedance = 2ohms.

Hope this helps.

How do i wire two fifteen inch subs to 2 ohms


Hello familia_gome,

If you have 2 subs that are 2 ohms, the final impedance will be either 1 ohm if they are wired in parallel or 4 ohms if they are wired in series. You cannot get a final load of 2 ohms. Unless your amp is stable down to 1 ohm (many amps are not), your best solution would be to wire the subs in series, positive of one sub to the negative of the other sub, and the remaining positive and negative to the amp. Yes, this will result in a 4 ohm load and the amp power will be reduced. But it is better than destroying your amp with too low of a load, and the subs will work fine, just not as loud.

I HAVE A JL AUDIO MONOBLOCK AMP 250


there could b allot of factors involving this problem first could and most important is to make sure theres no loose connections in your wiring and find out how ur subs are wired in. are they SVC or DVC (single and duel voice coils) also what are theyre impedences if SVC could be 2, 4, or 8 also the same as DVC but jus 2 sets of terminals. find out first then the reason i ask is cause allot of half way manufactures are installing a device u could say that will cause amps to automatically cut off when the load on the amp reaches its lowest impedence load so when ur subs are moving in and out that load varies with how far the sub is extending out jus cause a sub say its a 4 ohm SVC doesnt mean that when its pounding away the load may actually be 3 ohm when fully extended. find out these variables first and then reply and ill let u know what to do properly.

Ohm load???


You can't wire a pair of single voice coil 2ohm subs to achieve a 2 ohm mono load. Too bad you don't have 2 four ohm SVC's. Sorry
