Kole amp in protect mode?

I have a kole amp nitric XP2-2000 hooked up to two Memphis subs the subs are dual voice coil 4ohms and can handle 500 watts RMS when i tried to bridge the subs to the amp the protect light comes on but the amp works fine when subs are not bridged is the amp able to handle two 4ohm subs bridged? Thanks

Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

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

What would the best way hooking up a 15" memphis dual voice coil sub ran with a 1000 watt memphis d amplifier??


If the amp is a 2 channel I would hook up each voice coil to a different channel. Also, make sure you hook your amp up as close to the sub as possible. With a sub that size you need to eliminate any delay in signal transfer because the sub is so larg.

Trying to wire to 2 dual-voice coil Memphis sub-wooffers in box


If both subs are dual voice coil, you can wire one voice coil to other voice coil on each sub. Do this by running the ground of each coil to the ground of the other coil. Do the same for the positive. After doing this on both subs, you should have one ground and one positive per sub. Hook one up to the left channel of amp and one up to the right....This should work for you. If your amp plays for a while then goes into protection mode, then it cannot handle the ohm load.

What is the best way to wire two alpine SWR 1222D subs to a alpine PDX 1000 1


First off excellent choice on audio equipment, i guarantee you won't be disappointed. So your subs are dual coil 2 ohms. So wire each individual sub in series. If you don't know what this means i'll explain. On each sub there are 2 sets of wire terminals. Connect a wire from the one set's - to the other set's +. Do this on both subs and you will have the coils wired in series making each sub 4ohms. Now to hook the subs together you'll need to wire them in parallel. Now since you have your coils in series, on each sub you have one + terminal and one - terminal left. So run a wire from the + terminal remaining on each sub, and run them to your amp. Splice the ends of the two wires together and plug them into the + speaker output of the amp. Connect the two negatives in the same way and plug them into the - port on the amp. You will now have your amp running at its desired 2ohms. When wiring this disconnect the fuse on your amp power wire to avoid short problems. And if you get confused at all, and aren't sure what to do, ask again don't guess, if its done wrong you could severely damage your equipment. Hope this helped, enjoy the bass...

Ppi dcx 1500.1 is it 2 powerful 4 da 12in. L7?


Hello montyski20,

The amp outputs 500 watts RMS into 4ohms, 750 watts RMS into 2ohms and 1000 RMS into 1ohm.

The L7 can handle 750 watts RMS (375 watts per each coil). If your L7 is the 2ohm version, you should wire the voice coils in series, the positive marked coil to the negative unmarked coil. Then connect the remaining positive and negative to the amp terminals. This gives you a 4ohm load (500 watts). If your L7 is the 4ohm version, wire the voice coils in parallel, both marked and unmarked positives together, likewise both negatives and then to the amp terminals. This gives a 2ohm load (750 watts).

Paralleling the 2ohm sub will result in a 1ohm load (1000 watts) and that is too much for the L7.

Hope this helps.

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

How should I wire my 3 subs to the 500/1 amp???????


First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

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.

How should I wire up this amp and sub


The amp's not actually a very good match for the sub, since the sub can be wired for 2 ohms or 8 ohms, and the amplifier is most efficient at 4 ohms in bridged mode. My advice would be to wire the amp in bridged mode, and wire the sub for an 8 ohm load. To do this, the amp's (+) wire should go to the (+) terminal on one of the sub's voice coils. Then run a wire from the (-) terminal on the OTHER voice coil to the (-) terminal on the amp. The remaining (+) and (-) terminals (on opposite voice coils) should be connected to each other with a wire. Your original wiring setup had the amplifier connected to only one voice coil, while the other voice coil was shorted.
