Subwoofer seem to be broke

Hello, while I think that one of my subs had been damaged by an amplifier who was not working correctly. The amplifier damage only one of my subs!! Now, when I press the subs when all is off, it is ok no sound. But the other subs make a little sound when I press it. And when it play the subs seem to make a little sound like a wink wink, but it play louder as the other.. but I am scare that the sub will maybe in the future broke if I continue to use it, or there is a way to fix this problem?? Thanks again!! Sam

Re: Subwoofer seem to be broke

The one sub that you described is gone, there should be no reistance at all when you push on them. It sounds like you got your gains set to high on that amp (maybe the amp is underated for your subs). When you turn up the gain to high your cause your amp to distort and it can get as bad as sending a pure DV current to the sub. That DV current will blow subs because of all the force directed in one direction. If you think about it the amp takes a DC current and turns it into a AC current which creates the frequecy (rate at which it alternates) that alternating current pushes and then pulls on the sub keeping it within its boundries.

Could i wire my audiobahn Eternal subwoofers to my surround sound system?

is your subwoofer self amplified? if it has, you can connect it through audio sub output and in put to your self amplified subwoofer.. if it is not self amplified, you can still connect it but be sure it ca drive your subwoofer, it depends on RMS or watts of the original sub of the srround..or you can have a seperate amplifier only for your subwoofer.

I have a Jensen KS212 and I'm connecting it to a home theatre receiver direct to see if it works but nothing comes out of it. Does this mean the sub is not working or there's not enough power from...

Hi, welcome to FixYa..

Your subwoofer requires a seperate amplifier that has low pass filter in the pre out system, which means it will allow all low frequency signals from the input section of the amplifier/ crossover. Your receiver has combined signals of high, mid and midbass signals that will not be able to drive your subwoofer. That is the main reason why some receivers has "Subwoofer Out" to allow you to use "Active Subwoofer systems" (also known has self powered or has a built in amplifier w/ subwoofer)
For you to use your Subwoofer, it must have a seperate amplifier, connect it to Sub out of your receiver and from there you can hear the difference. Hope this helps.

How do u hook up a dual voice coil subwoofer ?

A dual Voice coil Subwoofer is like having two speakers in one, but the inputs from the amp to the sub must be the same level or you can over-heat the coils. Simply hook the subwoofer to your amplifier as if you had two separate speakers, make sure you get the + and - correct. If there is a level control on the amplifier for Left and Right, be sure to set these at the same level, also if the head unit has a subwoofer output for the amplifier be sure to use this
Hope this Helps GM

Sub keeps on sounding like a heartbeat and a blue light keeps on flashing every time this happens, there is no music or bass coming threw the sub... any soultions???

It sounds to me like your amplifier is getting caught in a loop-- the heartbeat is the subwoofer catching a surge of power from the amplifier. Make sure all of your connections are solid. If they are, try using the amplifier in another vehicle that is already set up for an amplifier. If it does not work, you may need to spring for a new amplifier.

My sub woofer will stop working if i put the bass up to loud, ill have to turn my car off and on to get it to work again. What could be the problem?

Seems like your power amp for the sub woofer may be going into protect mode/thermal overload when you push the volume too much. Therefore it shuts down. I am surprised the speaker hasn't blown yet.

As far as turning car off/on to get it to work, it's as if your car is the power switch.

Amp and speakers may not be wired correctly, as you want to make sure your amp/speaker ohm measurements are within a specific range for the amp and speakers work together properly. You may have it wired for a 2 ohm load, and maybe your amp can't do 2 ohms all day long.

Kicker Solo-Baric L7 S12L7 Car Subwoofer ... b-line or not ??

It is a normal subwoofer in a sense. These are very good subs. I had four in a regular cab s-10 and I just about died. I would recommend using a jl audio hd750/1. I was using two on my fouur subs and it worked great.

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.

Broken sub

Probably blown, check the wires going to the back of the speaker, if they are conncted fully. Are you hooking it up correctly to a AMPLIFIER? and if their is any signs or moderate or significant damage you probably got what you paid for.. Good luck

Low output on subwoofers

You may have wired the sub backwards or it could be only somehow hooked into one channel instead of 2. I think this is a wiring problem.

Wires on SUB - Make sure they are connected correctly
RCA leads to AMP
