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

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.

I have an Impulse 1252xi kicker and 2 12" kicker compvt 2 ohm shallow mount subs in custom ported box. How would I hook the subs up to keep the ohms correct and get the best bass I can get.

To properly wire your 2-ohm Kicker CompVT subs in a way that maintains a 2-ohm load for your Impulse 1252xi amplifier, you can use the following wiring configurations:
Assuming each Kicker CompVT subwoofer has a 2-ohm impedance:

Wiring Configuration 1: Series-Parallel Wiring for 2-Ohm Load

  1. Connect the positive terminal of the first subwoofer to the positive terminal of the second subwoofer.
  2. Connect the negative terminal of the first subwoofer to the negative terminal of the second subwoofer.
  3. Connect the positive terminal of one of the subs to the positive terminal on the amplifier.
  4. Connect the negative terminal of the other sub to the negative terminal on the amplifier.
This configuration results in a 2-ohm load. It combines the two 2-ohm subs in series (4 ohms) and then connects them in parallel, resulting in a final 2-ohm load.

Wiring Configuration 2: Parallel Wiring for 1-Ohm Load

  1. Connect the positive terminal of each subwoofer to the positive terminal on the amplifier.
  2. Connect the negative terminal of each subwoofer to the negative terminal on the amplifier.
This configuration results in a 1-ohm load. It directly connects each 2-ohm subwoofer in parallel.

Choosing the Best Configuration:

The Impulse 1252xi amplifier is likely designed to handle a 2-ohm load without any issues. However, it's essential to check the amplifier's specifications to ensure compatibility with a 2-ohm load.
Choosing between the two configurations depends on the capability of your amplifier. If your amplifier is stable at 1-ohm, you might opt for the second configuration to maximize power. If it's not stable at 1-ohm, go with the first configuration to maintain a 2-ohm load.
Always refer to the amplifier's manual or specifications to confirm its minimum stable impedance and adjust your wiring accordingly. Incorrect impedance matching can result in damage to your amplifier or subwoofers. If you're unsure, consult with a professional car audio installer for personalized advice.

How to wire subwoofers correctly.

If you're ever unsure about how you need to wire your subwoofers to get the correct ohm load to your amplifier there are a few resources to help. Usually in the owners manual that comes with your subs and your amp they include a detailed ohm load calculator. First step is to determine what subwoofers you have. Common subs come in a dual 2 ohm or a dual 4 ohm version or a single 2 ohm or a single 4 ohm version. Next determine what ohm load your amplifier is rated at. Mono "subwoofer" amps usually are rated x amount of watts at either a 2 or a 1 ohm load. This means you need to purchase the correct subwoofer combination to match your amp. If youre purchasing 2 dual voice coil 4 ohm subs then to maximize an amp you should buy a mono amp stable at 1 ohm. and Dual 2 ohm subs would need a 2 ohm stable amp wired in series parallel. A great resource for a beginner is to go to www.the12volt.com and on the top of the page find the words "subwoofer wiring diagram" and click on it. This will bring you to a drop down menu where you choose the number of drivers "subs" or "speakers" you have and then you choose the impedence in the next drop down menu. Next you'll be provided with multiple wiring options. Good luck and never think you can't do it yourself. Once you learn it's very easy to retain.

I just got a HS10 sub from Kicker and the red protection light is always on and I can't get it to work is there any advice y'all can give me to see if I can get this thing to work thank you ?

It sounds like you are having an issue with your Kicker HS10 subwoofer. The red protection light being constantly on could indicate that there is a problem with the subwoofer that is causing it to enter protection mode. Here are a few things you can try to troubleshoot the issue:
  1. Check all of the connections to ensure that they are secure and properly connected. Make sure that the power and ground wires are properly connected to the battery and chassis, and that the RCA cables are securely connected to the amplifier and the subwoofer.
  2. Check the amplifier settings to make sure that they are correct for the subwoofer. The amplifier should be set to "low pass" and the crossover frequency should be set to a frequency that is higher than the subwoofer's rated frequency range.
  3. Check the subwoofer itself for any visible damage or loose wires. If the subwoofer has been damaged or if there are loose wires, it may not be functioning properly.
  4. Make sure that the subwoofer is not being overdriven. If the amplifier is producing too much power for the subwoofer to handle, it can cause the subwoofer to enter protection mode.
I hope these suggestions help you get your Kicker HS10 subwoofer working properly. If you are still having issues after trying these steps, it may be necessary to contact Kicker for further assistance.

Will a pioneer receiver vsx d309 run 2 8 ohm speakers and 1 jl audio w3

It will drive the speakers but not the subwoofer. U need to connect the subwoofer pre- output from your amplifier to another amplifier that will drive the subwoofer.
If you connect the subwoofer directly to your amplifiers speaker output it will force the subwoofer to play the entire spectrum of frequencies (not designed to do that) consequently causing damage to the sub and maybe even the amp. So use the sub pre out.

hope this helped

Is there a crossover in the ada885 sub box do i disconnect when using external amp

usually the external amplifiers have potentiometers that you can adjust called sub sonic and LPF. Find what your sub needs to be setup to and set the LPF to that frequency, usually 40-60hz.
Find the tuning of your box or the sub sonic frequency cut-off and set it there. usually 30hz and under, this will keep your subwoofer from unloading and damaging itself.

I parelled one 15" q power subwoofer to my brideged pioneer amp.The amp got really hot and blew a fuse.How should I wire my dvc subwoofer to the briged amp.

Hello sir, hi, YOU DON'T bridge no more speakers, this upsets the impedance load of the amp. to install another sub-woofer, get another amplifier. You may have damaged your power amplifier, If you experience repeated fuse blows, your power amplifier is now SHORTED. This needs IC amplifier replacement.

Got jl300/2 amp confused which subwoofer sounds good

Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

Ccan it be bridged with a 5 ohm subwoofer?

Hello cameron_cran,

The information I found on the amp is that is a 2-channel and is bridgeable. It is stable in bridged mode to 4 ohms. You should be able to bridge a single 4 ohm sub without damage to the amp.

Hope this helps.

Audio problems

It sounds like this is a subwoofer box with a built in amplifier, is that correct? The issue you describe definitely sounds like a problem with either the amplifier portion or the signal to the amplifier. Do you have a way to confirm that the signal is getting to the amplifier from the head unit such as an oscilloscope or a known-good signal that you could try when the subwoofer doesn't seem to want to work?
