Question about Jensen XA2150 Car Audio Amplifier

1 Answer

Hi! I have a Jensen XA2150 Amplifier, from the speaker output I have connected a Subwoofer Sony 10 inch 1100W. Tha'ts gave me a nice bass sound, but now it's death! The amplifier have a 25A fuse, turn on the "JENSEN" lights but the subwoofer it's still death. I've tested the subwoofer without the amplifier and it's works. Essentially: The Amplifier tuns on but the output volume don't turn up. It's muted or death. I don't really know where is the problem, I've checked the wires, fuse, battery and subwoofer but still don't know how I can fix it and have my bass sound back. I'll appreciate if you can help me. Thanks. Best Regards. Ricardo. Chile

    Thanks for you faster answer.
    I have another thing to mention.
    When the amplifier turns on (with the "JENSEN" lights on) the POWER light and PROTECT light doesn't turn on.
    And I have some confusion wiith the subwoofer wires. The red must be in Speaker output L+ and the black one in the R+?
    I'm asking to be sure.

    Thanks again.

    I unscrew the cover but I didn't found any old fuse, do I have to unscrew the blue cover? Because I unscrew the bottom of the amp?
    Please...your help.Thanks.

    You will find it near where the power wire goes into the amp.So yes you will have to remove the blue cover also.

  • arkangelrl May 22, 2011

    Thanks for you help.
    I'll remove the blue cover and check the fuse inside.
    I'll tell you the result of the process.

    Thanks again, best regards.

Light turns on but no sound


This is a powered sub, which means it has it's own amplifier providing the power for big bass. When you removed the back you probably removed it's amplifier too so it's normal that now you only get the bass performance of a normal speaker.

How to i attatch jensen amp to pioneer deh-2200ub


You have two options here you can use the rear outputs and make sure you use the LPF low pass filter on the amp. Or you can use the speaker outputs and purchase a line out converter to connect rca's to the amp. The blue/white wire from the headunit goes to the amp remote turn on. power goes directly to the battery and ground goes to the vehicles chassis.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

Conncet a sony sub to a denon reciver


Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Bass in Car Gone, i don't know why!!!


Does the amplifier power up? If so, then check the voltage at the outputs...sounds like the outputs fried. Also, check the RCA cable to make sure it is getting a signal to the amplifier.

The 'Subwoofer' output on your receiver is used to connect to a powered subwoofer with a built in amplifier. Your KLH speakers use what is called a 'passive' subwoofer, it gets its power from the receiver and then passes the higher frequencies to the left and right front speakers after taking out the low frequencies for the subwoofer. A speaker system with a passive subwoofer is good for casual listening, but a powered subwoofer is required for really hearing low frequencies and rumble in movies. The KLH speakers you have were highly rated in their time for their price. The four satellite speakers and center channel speaker have very good sound compared to the little 'midget' surround sound speakers most people buy today.

Here's how you hook them up:

- The left and right front channels from your receiver terminals should go to the terminals on the subwoofer marked 'From Amplifier'
- Your left and right front speakers are then connected to the subwoofer terminals marked 'To Speakers', they do not connect directly to your receiver.
- Your center speaker is connected to your receiver terminals marked 'Center'
- Your rear speakers are connected to your receiver terminals marked 'Surround'

That should get you up and running. If the bass isn't good enough with the passive subwoofer, you can get a decent powered subwoofer like the Velodyne VX-10 for about $150 and 'kick it up a notch'. Good luck and enjoy....
