A speaker with dual 4 ohm can be wired in parallel (+ to + and - to -) to react like a 2 ohm impedance. Connect both speakers together in parallel (+ to + and - to -) for the 1 ohm impedance. I personally would not prefer nor recommand using a 1 ohm load on any amplifies.

I have two 12 inch 1200 watt kenwood excelons and i want to bridge them to the amp but i can barely turn it up with out blowing fuses


Please check the impedance of those subs. Are they 4 or 8 ohm speakers? Do they have dual voice coils? this app may not be capable of handling dual voice coil four ohms and you're trying to bring it down to a 2 ohm mono.

I have a mono amplifier hooked up to a 12 inch sub. I have everything hooked up. The ground is good. However, when I turn the gain/level up to around 55% the sub starts thumping loudly. Just a rhythmic...


There are a few things you can look at. Check to make sure you power is at a constant 12 volts. Usually a dip in voltage will set off a protection mode, but it protection is malfunctioning, this may be occuring. You also may need a larger guage wire for power and ground, depending on how many amps your amplifier is drawing. You subwoofer may be the problem too. Is it a dual 4 ohm, or dual 2 ohm? If it's dual 2 ohm and your amp isnt' one ohm stable, this could be causing the amp to overload. From your description it sounds like the amp is "clipping", so my gut tells me it's more of a power problem. Recheck all your wiring. If you have a multimeter to check your power, use it. Good luck.

I have a alpine type r 15 inch it has two hook ups i cant figure it out i have positive two pos and neg two neg and it keeps cuting out one bridge two amp plz help plz plz


Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

How do I drop olhs


To drop the ohms you wire in parallel. If your sub has dual 4 ohm coils you would connect both positives from the coils together as well as join the negatives together- this will give you 1 set of positive and negative wires-this + and - is now a 2 ohm load do the same to your other sub and you have a pair of 2 ohm subs. Wire the positives together from both subs as well as the negatives again and you now have a 1 ohm load. If you have dual 2 ohm coils you can get as low as 1/2 ohm of resistance.As far as i know the jl 500 puts the same amount of power into 1.5 through 4 ohms as long as you stay in that range your amp will be fine

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 do you hook up 2 15 inch cvr to 1 ohm


Hello juanelreypla,

If your CVR's have dual 2 ohm voice coils, they can only be wired for 0.5 ohm, 2 ohm, or 8 ohm final loads.

http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woofer_imp=3

If they have dual 4 ohm voice coils, they can be wired to a final load of 1 ohm. Wire the voice coils in parallel and then parallel both subs. Like the diagram in Wiring Option #1 shown here.

I have 2 15''s dual voice coil and i need to know how to wire them to my power acoustik bamf 4000 in a 1 ohm


most car-audio subs are rated at 4 ohms, as opposed to home audio's 6-8 ohms. If you have a pair of 4 ohm subs, wire all 4 positive terminals to the positive terminal on the amp and the sam with the negative sides. The key is to use the same length of wire on all connections.

15 cvr 4ohm trying to drop to 1 ohm


Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?

If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1

This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.


If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.

This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

Need to know how to wire 2 15 inch cvr to a zx1000.1 amp at 2 ohms


If they are 4 ohm single voice coil subs, just connect all the negatives together and then all the positives together. If they are DUAL vc's then need more info.
