I have two pioneer champions.

4 ohms each.

Only one will be powered at a time using the 1st positive and negative on the amp.

The other positive works with the first negative. But not the 2nd negative its supposed to be using.

Basically the 2nd negative will not work.

So I have them both hooked up to the same negative.

And this causes the amp to do into protection mode.

Whats wrong?

Should I wire the subs at 2 ohms each?

I have 2 subs and 2 amps both wired properly but one bose not seem to run how can i fix the problem please really stuck?

Fixed. That negative is not functional, but its not necessary to use it.

The subs were at 2 ohms each and that was causing the protective mode.

Rewired them at 4 ohms.

Works fine.

Separate positives, same negatives.

Thanks for the help.

The amp should produce no output when using the left negative and the right positive.

If the amp works bridged (left positive and right negative) with one speaker AND works when you connect one speaker from the left positive to the right positive, it would appear as though the right channel isn't getting any signal.

Try inserting only the left signal cable (nothing plugged into the right RCA jack) to see if the right channel will work when a speaker is connected to the right channel speaker terminals.

Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,

This will create a 4 ohm load on your amp.

Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.

That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

Ok, your post has two different models listed. Let's start with something you need to know about your amplifier. Is it one ohm or two ohm stable. This will make a difference. Also, whether your subs are single voicecoil (HFI12s4) or dual voice coil (HDI12d4).

Let's start with the easy scenario. Let's say your amp is two ohm stable and you have two single voice coil subs. It's simple. You go from the positive of the amp to the positive of both subs and the negative of the amp to the negative of both subs. This will provide a 2 ohm load to the amplifier, thus pulling all the power out of it.

Unfortunatley, if you have two dual voice coil subs, you won't be as efficient. You will only have the options of a 4 ohm load or a 1 ohm load.

This is where having a one ohm stable amp would come in handy. If the amp is one ohm stable, hook the positive of the amp to all 4 of the positives on the subs, and hook the negative of the amp to all 4 negatives of the subs. This produces a 1 ohm load.

WARNING!! If you have a 2 ohm stable amp DO NOT use the last wiring scenario. It will fry your amp.

Now, the last is a little trickier. This is for two dual 4 ohm subs. Follow closely. Hook the positive of the amp to one of the positives of each sub. (do the next step to both subs) Go from the negative of the voice coil that you hooked positive from the amp is hooked to, and hook that to the positive of the unused voice coil. Then go from the negative of that voice coil and hook to the negative of the amp. Make sure this is done on both subs. This will give you a 4 ohm load.

Hope this helps

conect one of the positive terminal from the sub directli to one chanel of the amp, and do the same with the negative,and do the same with the others terminals from the sub conect to the other chanel

You are doing right on what you described. I really like to work with a clearly described what involved in an issue.

Now we have to use a Voltmeter to check if there is power to the amplifier. If there is power to the amplifier terminal, then the problem is at the amplifier, not the connection. Let check it out:

1- Turn on your Kenwood radio, make sure to hear sound from your regular speakers.

2- Turn remote control knob to the mid level between min and max.

3- Measure the blue wire where you spliced to ground to see if you have 12V, if it is not then the problem is right there.

4- Measure the Red wire power from the Amplifier to ground ( the bolt that you connect the negative power to see if there is 12V, if not trace back to the Fuse that you inserted between the positive terminal of the battery and the wire going through the firewall to correct it.

5- If you have 12V at step 3 and 4, then you have a defect unit, return it to the manufacturer for a replacement.

Hello ronnieyannon,

A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.

Positive on sub to Positive on amp.

Negative on sub to Negative on amp.

This is your only possibility.

Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.

I'm not sure what pinoeer amp you have. If I remember correctly some are 1 ohm stable. In this case you would be able to wire everything in parallel. Meaning, with the voice coil, wire the positive to positive, and the negative to negative. Then wire the subs together positive to positive, and negative to negative. This will give you the total impedence of 1 ohm. If it isn't 1 ohm stable the best you could do is 4 ohms. To do this you would need to wire the voice coils in series and the subs in parallel. Meaning, wire the negative to positive and the positive to negative. Then take the subs and connect the positive to positive and the negative to negative. I hope this isn't too confusing. If you need further assistance let me know. Good luck

you haave either connected it incorrectly.make sure the ohm of the speaker matches that of the amp ..connect the positive coil to the positive coil at the back of the sub and the same for negative .then run your cables to the amp .you should only have one positive cable and one negative cable .this connection will create a 2 ohm connection make sure the amp can handle that load .prefarably using a 2 channel bridgable amp or 1 channel monoblock

First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.
