I have 4 wires what do they do I no to of thim will go to my Kicier ame I Ddont no were the other to go


OK, I am assuming that you have 4 wires coming from the subwoofer itself. Your subwoofer has dual voice coils, this means there are two positives and two negatives. Look closely at the posts on the subwoofer and you can tell. These wires will go to your amp, all four of them. Here's the tricky part. You need to know if your amp is a monoblock (single channel) or two channel amp. Also, what ohms is it stable at (4, 2, or 1). If you have a monoblock stable at one ohm, take both positives from the sub and put to the positive of speaker output on the amp. Then put both negatives from the sub to the negative speaker output of the amp. If your sub is dual 4 ohm voice coils, this will give you a 2 ohm load. If you have a dual 2 ohm voice coil sub, this will give you a 1 ohm load. If you amp is 2 channel, just hook one set of positive and negative to one channel and the other set to the other channel. Hope this helps

I have a alpine type r 15 inch it has two hook ups i cant figure it out i have positive two pos and neg two neg and it keeps cuting out one bridge two amp plz help plz plz


Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

I need to hook up two audiobahn A1200Q subs to a A1300hcq amp


The amplifier is only stable to 2 ohms.
Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.
You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

I have a ly1440 amp how can i wire it to my hk15x2


This subwoofer has (2) 2 Ohm voicecoils.
Which means you will only be able to wire a 1 Ohm or 4 Ohm configuration for your amplifier.
The Model # you listed for the amplifier is not a valid one.

If your amplifier is 1 Ohm mono stable...
you wire both (+) Sub to amp (+)
and both (-) on Sub to amp (-)
This is PARALLEL wiring and lets the amplifier SEE a one ohm load

If your amplifier is NOT one ohm mono capable - your only other possibility is a 4 Ohm load.

Wire from (+) on amplifier to one (+) on the sub
Then Wire from (-) on amplifier to the OTHER terminal's (-)
You will have one (+) and one (-) left on the subwoofer - wire them together.

This is SERIES wiring, and nets a 4 ohm load for your amplifier.

There is no other configuration for wiring one Dual 2 ohm sub.

Wiring a 10 inch dual voicecoil dub100 so its bridged the right way


yes sir. You can find out every single option for the amount of subs and the impedence. This will show you your wiring options. Plus remember when you bridge your amp you are Halving the ohm that is going to the 2 channels. SO if it is stable at 2 ohm at each channel. And you already have a 2 ohm load from your subs your amp will go into protection over and over again and eventually fry up cuz you will be putting 1 ohm load at each channel.

15 cvr 4ohm trying to drop to 1 ohm


Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?

If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1

This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.


If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.

This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

How to wire 2 dvc subs to a orion 2150sx ? dont know the wire colors or how to hook um to my amp.


what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??

Orion SX / GS / HCCA amp Wiring guide:

Orange = Right Positive
Black/ Orange = Right Negative
Yellow = Left Positive
Black/ Yellow = Left Negative
Blue = 1+1

Bridging of SX or HCCA Amps:
1. Use the Orange wire for Positive.
2 Use the Black/ Yellow wire for Negative
3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

Finally, take a - from the second woofer to the amplifier -(black/yellow)

Now you have a 4 ohm load on your bridged channels.

These subwoofers are dual 4 ohm voicecoils.

Parallel wiring the 2 voicecoils would net a 2 ohm mono load.

Connect both + on the sub to the + on the amp.
Connect both - on the sub to the - on the amp.

Many professionals simply jumper the 2 + and 2- on the sub.... then run 1 set of wires from one of the terminals to the amplifier.

REWIRE


Series wiring of a 4 ohm DVC subwoofer will result in an 8 ohm load.
See the following diagram.
The diagram listed has a dual 2 ohm voicecoil, netting 4 ohm, however in your case, the dual 4 ohm sub will net an 8 ohm load.
