Hello, I have another suggestion: if it's a ' whisteling noise' coming from the sub woofer,it could also be air coming from a part of the subwoofer enclosure it's not meant to,check to see if a part of the enclosure has a crack,>or< where the glue has cracked away,( a port is a good starting point: also check : if the port is glued in,check to make sure the glue in the port hasn't broken away)also check if the subwoofer faces out,where you can see it,check to see that it still has all the screws attatched,whisteling can happen >if< a screw,or screws have fallen out,or have come loose. I hope I can be of assistance.

Do you mean that when your sub woofers are working, there is a whistling type sound coming out of your ported box? is this sound coming out of the port? If it is, this simply means that the port was not properly made, and is actually acting as a whistle. If the port is a removeable plastic one, check to see if it has the flared end (like a trumpet or trombone) on the internal end of the port (inside the box) if it doesnt, go to your local stereo shop and see if they can get you ones that have flares. Sharp edges anywhere in an opening that air passes through will act like a whistle. Annoying isnt it?

I'm having a problem when i listen to music threw Bluetooth on my car stereo, when i play music using Bluetooth from my phone my subwoofers don't turn on, but when i listen to the radio my subwoofers work

Generally, subwoofers require separate circuitry. Your car radio has that circuitry. Bluetooth is set up for stereo only and your phone will only supply stereo output

Wierd problem with my subwoofers please help

It sounds like your RCAs are pickin up noise somewhere, are your rca cables next to your amp power wire? this could be the problem. Just recheck your signal wires and make sure they aren't close to any significant power cables. Also does the noise only come from your subs or your car speakers to? If it comes from all your speakers you may have a headunit problem... hope this helps

Speakers have hissing noise coming out of them

Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.
