I'm getting a funny popping sound from the sub-woofer it appears; because when unplugged I don't hear it.


Looks like the capacitors on the amp are going.
If you hear a hummm sound when you turn it on without anything playing on it, then the capacitors are to blame for sure -> Time to replace the capacitors.

Box specs and airspace for 8 inch subwoofers


<span>Regardless of your wattage rating on your sub woofer, sub woofers</span> differ in only one way. You get an "Open Air" and a "Closed air" <span>Sub woofer</span>, That being said, you'll have to check on your magnet which one you have, to make the boxes for that particular sub woofer. If it is an "Open air" <span>Sub woofer</span>, you should see a hole with "wire mesh" or "metal grid" in the center, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.<br /><br />If it is a "Open air" sub, your boxes should always be sealed with silicone sealant, and no ports are to be cut in your box.<br /><br />Regarding the "Closed air" <span>sub woofers</span>, you should have 2 ports cot in the corners of the boxes just below your sub on the face of the box, and the port sizes should be around 50mm in diameter. Get yourself some 50mm PVC drain piping to use as ports. Firstlycut yourself a 100mm piece and insert flush with the front of the box. Test your sound. then try a 150mm piecs and test again. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require. Carry on testing the sound on each increment until you find the sound you want, Then silicone the port to the box for permanent fixing.<br /><br />On a 15 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be a box of 9 inches high, x 9 inches wide, x 9 inches deep. Or 400mm high, x 400mm wide, x 400mm deep. <br />Enjoy! <br />

My Onkyo sub-woofer sounds like something is loose in it or rolling around...the sound is similar to shaking a can of spray paint. When I plug it in to the system it sounds crackly. If i turn the volume...


sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg. images?q=tbn:and9gcqv8lxhmuosnjkfywvef7uujnntmudkhhpl-pghy0i7xushrda- torn cloth- images?q=tbn:and9gctcogf_osbsmo3vmcu1vjnpozksylq4nojwpbojuo3w28zvb3honw

Subwoofer FPS 1000 4.1 sound bad


hello,

I had a problem closely with my FPS 1000 4.1 sound works four point surrond : my subwoofer sounds a metallic noise when the bass are loud.
Maybe it is the same problem ? :

It were vibrations that go through the subwoofer and cause the noise.

Check the four screw well (the four hole on the back of the subwoofer). Put your finger on them to clog them and hear if your problem is solved.
If yes, put scotch on them.

Secondly (i think you have disassemble your subwoofer), you can put silicon joincture on the box near the circuit, under the translucides cables. (the box where there are the plugs). >> if there are any hole between his box and the speaker, there will be some metallic noise (vibrations trough the box and the back plugs).



bye

Amplifier has no sound


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.
A thumbs up would be greatly appreciated if this answer is helpful to you. amplifier-no-sound-peeu4x5nsxvd53n2rwetiqa4-3-0.jpg

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

One or two


IMO 2 would be best. A good 10" woofer will give you good all round bass but wont rock your block off. The bigger your woofers the more low end base you will be able to produce so a 10" is a good balance between low end and thumpy bass for a full sounding system. The type of box you decide on encosing the woofers in will also affect your sounds. Consult your local car audio experts for more info. Good Luck
