Wiring How do you wire up a DA 12" sub to an amp? I have 2 + and 2 - on each side. No matter how I hook up the wires, no sound comes out. What am I doing wrong?

1st make sure your amp is coming on. Use another speaker that you have heard play to test it.
Next test the woofer with a 9 to 15 volt battery. Touch the battery leads quickly across the + and - on one side at a time. The speaker should move and make a pop on both voice coils.
If the amp plays and speakers play, then you need to know the power rating and impedence stability of both amp and speakers. That will determine how they are wired up.

Hello,

It does sound like a problem either with the amp itself or the wiring. Since the wiring is the easiest thing to check and cheapest to fix start here.

1.Make SURE the ground wire is secured to the frame of the vehicle.
2.Make sure the remote wire is hooked up properly.
3.Check the component/rca cables
4. Check the settings on the amp itself

Post back and let me know if you find anything wrong with one of those troubleshooting ideas.

How do you hook up 2 12" L7's to a kicker 1200.1 amp?


You have a 2 ohm stable amp, and dual voice coil subs.. The L7's come in both Dual 4 ohm, and Dual 2 ohm, so you have to know what impedance your coils are prior to wiring. HERE is a nifty little guide that will show you how to wire your subs. DO NOT WIRE THE SUBS LOWER THAN 2 OHMS ON YOUR AMPLIFIER!

Subwoofers pop then immediately produce no sound


Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.
Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING
In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.
Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS
For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

I have a jbl W15GTi MKII 15 inch and on the speaker it has to a a an b side and two wires no each side how do you hook it up


Your speaker has dual voice coils. You can hook it up so that it is 2 ohm or 4 ohm depending on wat the amp can handle. You can try hooking it up by matching the colors or like any other speaker.

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.

Wiring diagram


The LEd wires need a wire run from the speaker to the Fuse block in your car. The small Red wire from the LED will be the one that hooks to Swtiched 12 Volts supply on the fuse block so that your Led Turns on when you turn the keyswitch on. The Black wire goes to ground, or to a metal part of your cars body, probably the same point where your Amp is Grounded.

The Octane R10 is a Single Voice Coil or SVC.
AMP+ to Sub+
Amp- to Sub -
Use 12 guage wire.

Wiring


You may be surprised to learn that even though there is a negative and positive on the sub it usually dont matter all that much because that amp allows you to switch the polarity of its outputs to allow your mids to sound better... anyways on to your question To wire a sub it depends on how many you have, if they are dual or single voice coils, what impediance your amp is stable at. Tell me what type of amp you are hooking this subwoofer up to and how many are being connected. And ill try and give you the best way to connect the sub(s) to your amp.
