Speaker will not turn on

The speaker resonates with itself, reabsorbing the, little as it may be, and then amplifies it, spits it out, reabsorbs it... It goes on as long as no other input is connected.

turn or flip the LPF and sub sonic buttons to see if they will help.
there are other buttons called gain that you may have to turn to bring up the volume.
its very likely your eq buttons that you have to mess with to get it right. post up pics if you can.

This really depends on the setup you intend to create in your vehicle.

The Amplifer (amp) needs to be matched to the speakers you intend to run.


As a rule of thumb, the power of the amp shouldn't exceed the max. power of the speaker (this may damage your speaker). Instead, the amp's RMS output power should be at 75-100% of the speaker's RATED (RMS) input power. NOTE: this must NOT be confused with max power.

Ideally, you want to run each speaker with its own amp channel.

A subwoofer will usually require a hi-power single channel amp, or a 2 channel amp, bridged into 1 (to increase power output required for the sub).

Here are some examples in simpler terms:

1 channel (hi power) amp can run a subwoofer.
2 channel amp can run 2 speakers, or 1 sub (bridged).
4 channel amp can run 4 speakers, or a combination of 2 spkrs + 1 sub (bridged), or perhaps 2 subs (bridged).

Hope this makes sense.

Hi, my name is John. Welcome to FixYa. Turn your volume up to MAX, then turn your RF GAIN to MAX. If same, plug in a external speaker in back of radio into the external speaker jack. see what happens. If loud, re-place the speaker in the radio. Let me know how it goes, glad to help you and thanks for choosing FixYa....John

Oh, sorry for the clarification post! I must have hit the wrong button!

Sounds like your master volume is turned up too much. The channel volume will make the squealing go away(caused by high gain and humbuckers). The best thing to do is dial in your favorite presets and change the channel volume to the correct level with the master volume where you usually keep it. I use my Spider Valve at master volume at about noon and the channel volume between nine o'clock and noon. Let me know if this does not solve the problem......

Right-click on the speaker icon in the lower right of your screen and choose Open Volume Control and check all volume levels (make sure they are not set to high). If this doesnt work then when you right-click, choose Adjust Audio Properties and search around for volume controls (maybe try the Speaker Volume button).

I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.

You can read a similar guide here http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen but I will shortly be uploading a guide on the buzzing problem!

have your built-in amp checked for trouble. there should be trouble in the output stage feedback loop. this is something to be done by a repair technician

I had the exact same problem. In order to "almost" balance the center with the other channels I had to give the center +12db gain and the other channels -12db. So after I got that far with level calibration I tried some tv sound, well the center although was playing sounded like the highs were missing and a bit distorted. This is the good part, I turned the volume all the way up real fast, somewhere near max something fixed itself, the center became very loud. Now it works just like new. Hope this helps. BTW, the problem existed the same for sub channel, so when the center started working so did the sub.
