Question about Jl Audio 1000/1 Car Audio Amplifier

2 Answers

Input sensitivity im trying to hook up my jl 1000.1 to 3 12's, theyre each dvc 4 ohms and im running them in a series so it comes out to 2.7 ohms, ive been trying to use a multimeter to check the input sensitivity so i dont blow another set of subs but everytime i bring the multimeter in the car it freaks out, i have a test disc and i have everything hooked up fine its just the stupid multimeter thats being wierd....help?

Depending on what subs you have, if they are jl 12w6's, you should really have another 500 watts. the 1000/1 isnt really enough to make them pound.

Make sure your multimeter is set for AC voltage.

Do you bridge a 850.4 four channel amp when it is 2 ohm stable and ur subs are wired up as series/ parallel and there 2 ohm dual voice coil speakers


If you wire 2 ohm dvc speaker parallel that would give you a 1 ohm load. If your amp is only 2 ohm stable that would not work. You would have to wire the speaker in series giving you a 4 ohm load. Then you can bridge the 4 channels into 2 with each speaker running at 4 ohms.
If you want to run a 2 ohm load use all 4 channels on amp and speakers. No need to bridge.
For 2 ohm DVC:
Parallel = connect both + and - together. = 1 ohm
Series = connect + from 1 channel to - from the other channel. = 4 ohm.

How do you wire two dvc 4 ohm ma1500xl speakers to a jl audio 1000/1 amp


series/parallel - the JL amp is regulated, so you get 1000watts rms at 4ohm, 2ohm, and 1.5 ohm.

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.

Need help.. I have two 12 inch dual voice coil kicker comp vrs.. they are 4 ohm subs..how do i wire them to get a final ohm load between 1.5 to 4ohms in a dual enclosed box...Im hooking them up to a jl 500...


To do this they MUST be wired in parallel, IE: Plus to Plus, Negative to Negative. 2 4 OHMS in parallel is about 2 OHMS in series it would be 8 OHMS... series is positive to negative. Are you using a crossover network?

How do i wire two audio pipe dvc woofers to this amp. do i use all four terminals on da amp. jl audio 500.1


Hello smoovek2008,

The JL Audio 500/1 outputs 500 watts RMS into a load from 1.5 to 4 ohms. Whether your subs have 2 ohm or 4 ohm voice coils, they should be wired in series and the subs paralleled to the amp. The final load to the amp will be either 2 ohms or 4 ohms, both of which the amp can handle. If you parallel the voice coils and then parallel the subs, the final impedance will be either 0.5 ohm or 1 ohm, both too low for the amp.

You can wire each sub to a separate set of terminals or both to the same set. The terminals are connected internally. It doesn't matter which of the +'s or -'s you use.

Hope this helps.

Ohm calculations; 4 and 8 ohm sub woofer?


+ output from amp to + input of 4 ohm to + input of 8 ohm AND - output from amp to - input of 4 ohm to - input of 8 ohm is a parallel circuit = 2.66 ohm impedance load for amp
+ output from amp to + on 4 ohm - on 4 ohm to + on 8 ohm - on 8 ohm to - of power amp is a series circuit = 12 ohm impedance load for amp. Clear as mud??

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.

REWIRE


Series wiring of a 4 ohm DVC subwoofer will result in an 8 ohm load.
See the following diagram.
The diagram listed has a dual 2 ohm voicecoil, netting 4 ohm, however in your case, the dual 4 ohm sub will net an 8 ohm load.

This is a single channel amp that puts out about the same power at 4 Ohms or 2 Ohms. If you have two 4 Ohm single voice coil subs, then wire them parallel (both pos and both neg) to achieve 2 ohms. If you have two dual 4 Ohm voive coils, you want to do a series - parallel config to get to 4 Ohms (voice coils in series, then parallel the subs). Same with DVC 2 Ohm subs, series parallel = 2 Ohms. Do NOT go below two Ohms. You will blow the amp (actually, it'll do 1.5 Ohms). If you happen to have 2 Ohm single voice coil subs (not as likely) run them in series. Most amps will put out about twice as much power at 2 Ohms vs. 4, but this amp is designed to put out about the same. Hope this helps!
