How should I wire up this amp and sub

OK here is what I have, and I cannot find my amp manual. Kole Q2-480 amp Amplifier Type Dual Channel Bridgable Bridgable RMS Power at 4 Ohms 100 W x 2 RMS Power at 2 Ohms 125 W x 2 Performance Frequency Response 10 Hz - 30000 Hz Signal to Noise Ratio 98 dB THD at Rated RMS Power 0.02 % Crossover / Equalizer Bass Boost With Bass Boost Low - Pass Frequency 30 Hz - 500 Hz High - Pass Frequency 50 Hz - 500 Hz Other Features MOSFET Circuitry Yes 3 Way Ready Yes ------------------------------ Audiobahn AW831T 8" sub # 8" Natural Sound Subwoofer # 30 oz. Strontium Magnet # Power Handling: 200 watts R.M.S. # Frequency Response: 30Hz - 1kHz # Efficiency: 90.3 dB # PHAT Foam Surround # Non- Pressed, Non-Transfer Paper Cone # KM3? Coated for Virtually No Cone Distortion # 1.5? 4-Layer ASV Voice Coil # Dual 4 Ohm # 2 Ohm or 8 Ohm Operation --------------------------------- Empty MTX thunderform -------------------------------- Whats the best way to go about wiring this? The way I did it to test it out, was to bridge the amp, have the amp + wire to go the + terminal on one coil, the - amp lead to the other coils - terminal, then run a wire from the remaining + and - terminals on the sub. This sound right? Was pumping far less bass than I expected (and I wasnt expecting much) so want to make sure I am not doing this wrong.

    The way you described to wire it is the way I had it. I have it like the pic at this link, to be sure is that what you were suggesting?

    Oh and thanks for the REALLY fast response! Do you think this is the way it should be wired?

    No way to get that sub to run at 4 ohms is there? I know the amp runs at 250rms @4ohms bridged. I may look for a new sub anyway, this thing doesnt fit all that well in my thunderform anyway!

  • Ray jjj Jun 14, 2007

    Thanks for the help and fast responses. I have up on that sub and am looking for something new. The shallow mounting depth of 3 7/8 is going to make finding a decent one a chore!

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.

    Yes, I misunderstood your first description. I think the first diagram is the safest way to wire it. Here's the deal: the first diagram results in an 8-ohm load for the amp. This reduces the amplifier's power output in bridged mode, but the amplifier can run it safely. The second diagram, with your subwoofer, would result in a 2-ohm load at the amplifier. This would result in much more power, but there is a risk that the amplifier could overheat and shut down, or (in extreme cases) might result in amplifier damage. Most 2-channel amps aren't stable with a 2-ohm load in bridged mode.

    There's no good way to run that sub at 4 ohms. What you need is a single voice coil, 4-ohm sub rated for 250 watts; or a dual 2-ohm voice coil sub. Good luck!

I have two 12" jl w3v3.4 subs and a rockford 1500.1

Based on your setup, I would recommend wiring your JL W3v3.4 subs in a dual 2-ohm configuration. This will result in a 1-ohm load to the Rockford 1500.1 amplifier, which is within its safe operating range.
To wire your subs in a dual 2-ohm configuration, you would connect the positive terminal of one sub to the positive terminal of the other sub, and then connect the negative terminal of one sub to the negative terminal of the other sub. Then, you would connect the positive and negative of the combined subwoofer terminals to the positive and negative terminals on the amplifier, respectively.
Here's a diagram to help illustrate the wiring process:
luaCopy code
+ Sub 1 + ' --- ' +-------+-------+ ' ' + + ' ' + Sub 2 + Positive from Sub 1 -----> Positive from Sub 2 Negative from Sub 1 -----> Negative from Sub 2 Positive from Subs -------> Positive from Amp Negative from Subs -------> Negative from Amp
Keep in mind that you should always double-check your wiring with a multimeter to ensure that you've wired everything correctly and to avoid damaging your equipment. It's also a good idea to consult the owner's manual for your amplifier for specific instructions and guidelines on how to wire your subs.

Zx-8100 amplifier is red lighting.

try wiring them differently. here is a link for u to go to http://www.crutchfield.com/learn/learningcenter/car/subwoofers_wiring.html . once there find your amp configuration (ie. mono, or 2 channel) then down to the type of subs an how many subs ( ie. 2 dvc (dual voice coil) 4 ohm subs) an that will show u how the subs should be wired and wired to the amp.

Kole amp in protect mode?

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.

How to wire 2 ohm 2 12ich alpine type r's to box terminals?

Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

Kole kx2-1440 wiring da amp up right

It is correct to connect the amp turn on wire to the amplifier remote. 5V is sufficient to turn most amplifiers on... It should be 12V optimally.
If the amplifier is not turning on with the ant. remote, the problem is with the amplifier.

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
