My bass amplifier makes that weird noise that other speakers and stuff make that almost sounds like bip bip biiiiiip bip bip but its only when the subwoofer is on

The small fan or buzz noise you are hearing from your Fender 150 bass unit is likely due to normal wear and tear. Over time, components inside electronic devices can begin to wear down or become loose, which can cause the unit to generate noise. However, it's possible that the noise is being amplified through the speakers due to a grounding issue or other electrical interference.
Before attempting to open up the unit and clean it, try some basic troubleshooting steps to isolate the issue:

1. Try using a different cable to connect your PC or iPad to the Fender 150 bass unit. Sometimes cables can become damaged or worn, which can cause noise or interference.
2. Move the Fender 150 bass unit to a different location in the room to see if the noise changes or disappears. Sometimes nearby electrical devices or lighting can cause interference with audio equipment.
3. Try using different speakers to see if the noise is still present. If the noise disappears, it's possible that the speakers are causing the issue rather than the Fender 150 bass unit itself.

If none of these steps resolve the issue, it may be necessary to open up the Fender 150 bass unit to inspect and clean the components inside. However, if you're not familiar with electronics and don't feel comfortable working on the unit yourself, it's best to take it to a professional technician for servicing.
It's important to note that while the noise may be annoying, it's not necessarily an indication of a major problem with the unit. If the Fender 150 bass unit is still functioning properly and producing the sound you love, it may be best to simply live with the noise rather than risking damage to the unit by attempting to fix it yourself.

try taking out the capacitor and wire the amp up with out it. it sounds like the cap is back feeding or discharging voltage when it should not be . if you reinstall the amp with out the cap and noise goes away buy a new cap or do away with it .

sounds like you have some wires crossed. check your radio setting and make sure that the subs are only playing bass and no trebble. buy some new rcas

check your rca's are they hot too? if so you havea bad ground internally(amp) or externally.

Listen to the output with headphones to check for noise.

OFTEN the output of a drum machine is CORRUPTED by an inadequate sound system. The waveforms generated by a drum machine tax the sound systems. A bass drum output can drive the speaker cone such that it goes beyond the linear range that the speaker and amplifier can handle and this appears as "noise". The noise may sound like a buzz or totally break up.

Turn the volume down and see if EXACTLY the same noise appears at low levels. If not, then saturation of the amp and speaker is likely. Continued use while it is doing that will often destroy the speaker.

Typically you will hear a popping sound when the bass hits, or you may not have any sound at all.......If the sub sounds good then your ok.

On a side note, pulling on the cone while the sub is in operation can damage the unit because it cannot move freely under load

If your speakers not wired up properly sometimes the bass can shake the wire off and it leads to a horrible crackly noise, make sure it's securely wrapped around and tied to the terminal. Otherwise it could be a blown speaker or you are trying to put more power into the speaker than the speaker can handle.

I assume you are using XP. Try these steps.
1. Open 'Sound and Audio devices' in Control Panel.
2. Select 'Advanced...' button near bottom.

3. Select 5.1 system

4. Start playing a sound.
5. Set the volume control of the subwoofer to the middle position.
6. Open volume control and adjust Master volume to a comfortable level (i.e. until there is no hum).

Also make sure you haven't muted any sound device except microphone. I think your problem is you have set it to the maximum level. So decrease it.
7. Mute the sound and check.
Good luck! Let us know the result.

HAVE YOU TRIED THE BEST QUALITY HEADPHONES LIKE SONY AND DID YOU CHECK YOUR COMPUTERS VOLUME?

Disconnect all the speaker wires from the amplifier that runs the 6-speaker system. Switch off the amplifier or disconnect the remote turn-on wire, then re-connect it. Does the power light still flash with no speakers connected? If so, your amplifier is probably damaged. If not, then connect one speaker and see if it plays. If it doesn't, disconnect the first speaker and connect a different one. If the first speaker plays, continue connecting the rest of the speakers until you find the one that's causing the problem.
