It can be many things it possible the amp cannot handle the 4 ohm load and simply goes into power protection mode. Also make sure your using the correct gage wire to run power from your battery to the amp to thin and it wont have enough power to perform.

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.

Wiring a crossfire vr602 at 4ohm


OK what you are saying now is that your speakers are dual voice coil; models? 4 Ohms per Coil? I have always used single 4 Ohm Voice ciol speakers since amps are mostly based on 4 Ohm outputs. but you can get 8 Ohm dual voice coil subs also. With 8 Ohms per coil you can get 4 Ohms if you parallel the wires. What is best for you and will get you the most stable power and still will be in the specs of that amp is to run the amp in BRIDGED MODE running each subs voice coils in series with each other then run those 2 subs in parallel to the amplifier giving it a 4 Ohm load. So, your will have two sets of wires from your amp 1 for each speaker. Then you will take a short piece of wire that will connect the + to the - of each voice coil then hook up the wires from your amp to each sub What it will be is 4 Ohms + 4 Ohms = 8 Ohms per speaker the 8 Ohms in parallel each speaker to the Bridged amp output using just the + from one channel and the - from the other will give you a total of 4 ohms and power out put of 600 Watts so that ends up being 150 watts per voice coil or 300 watts each speaker

I have an old soundstream reference class a 5.0 and a set of mb quart pwe 254 10 duel voice coil subs. i would like to know how to wire this set up for the most power. parrallel the voice coils then run...


The Soundstream Class A 5.0 will deliver its full power at 1 ohms mono.
I think your subs are two dual 4 ohm voice coils.
If you wire the voice coils for each sub in PARALLEL, that's 2 ohm for each sub. To get 1 ohm mono, you need to hook up the subs in PARALLEL to the amplifier, in bridge mode. That's the way to get to 1 ohm mono. Please add a fan to your setup as the amplifier will get very hot. You will need to use a relay to hook up the amplifiers and fan(s) to or you will damage the remote ouput of your HU (if you hook up the fan straight to the remote of the HU) as the remote output of the HU is not designed for the amount of current a fan draws.
Good luck. If you need help with the relay issue, have a look here: http://www.caraudiohelp.com/newsletter/multiple_amplifiers.htm

Why does the kenwood kac-9103d has two sets of terminals if its a one channel amp so how do i hook up a dual 12 phoniex gold 1200 watt sub to it


Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

Want to bridge my subs I have a kenwood kac-719


from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

Wiring options for amp


Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.

What subs do you have? Is this amp 1 ohm ono stable?

Connecting a subwoofer to a mono amp that has 2 sets of terminals


ok this gets confusing sometimes. Ok first look to see what ohm your subs are. If you have a dual 4 ohm sub When you run that on sub + to + and - to - then that will make that sub 2 ohm. its different on ohm if the sub is say a 8 ohm then putting the wires that way will bring that sub to 4 ohm. Now lets say you have 2 subs that are dual 4 ohm and wire both of them + to + and - to - and go bridge the amp which would be both wires from sub both + together and both - wired bridge on the amp will make it a 1 ohm to the amp. Please post what ohm your subs are and i can tell you alittle more about it

I have 2 kicker 07CVR124 12" dual voice coil with a 800 watt mono pioneer amp. How do I wire it correctly


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

Pioneer prsx720 wiring question


If the subs are dual 4 ohm voice coils, you could hook the DVC's of each sub in parallel ("+"'s together, "-"'s together) making each sub essentially 2 ohms. Then connect one sub to each channel of the amps. This will put about 200W on each sub.

Unsureness of wiring configurations.


Mamola,

Get an amp with at least 200 Watts RMS. The RMS value is what is important about driving Subs. This could be proclaimed to be a 1000 Watt amp. REad the RMS value.

Wiring. It is better to series your Speakers to give them and your amp more reliability,

Get a Mono or Bridgeable amp. If it si bridgeable, BRidge the output as described in the manual you get. Some Amps have a diagram right on the output..

AMP+ to Sub1 +
Sub1 - to Sub2 +
Sub2 - to Amp -

Get a 4 Guage wring kit. Run your power wiring down the Drivers side, and Audio signal wiring down the Passenger side, keep the two separate.
