Now to most people bass is just bass, but there is different variations of it to define how it sounds. Some like a louder boomy spl sound ideal for rap music, while others prefer accurate precise punchy and tight responses. Now the enclosure plays a very important factor, since a sealed box is know to provide more of a punchy and tight sound. A ported can also achieve this but it will always been kind of sloppy while still being slightly boomy on certain lows. If you want to improve the amount of tight punchy bass from your car subwoofer, you can add Polyfill stuffing. This is white fluffy cotton looking stuff that you can get from your pillows or the local hardware store for not much. When you place this inside the box the speaker box it will think that its placed inside a bigger box. This is because it slows the speed of the bass waves making it sound more deeper and tighter.
When adding polyfill to the sub box, you need to ensure that you don't over stuff it as its a damping material. I have seem some young kids that get overly carried away and stuff the whole bag inside the box. This will have a bad effect of the sound because overstuffing the box with polyfill will most likely increase the internal cubic volume far more than what the manufacturer recommends. This is why its very important just to add the right amount to stay just under or at least match the internal volume size the manufacturer recommends. You can add polyfill stuffing for all kinds of speaker enclosures including sealed and ported vented designs.
1) Disconnect the speaker wires connecting into the terminal cup from the car amp.
2) Take the sub box into your workshop.
3) Get a screwdriver to remove the screws holding the speaker into the box.
4) Carefully lift out the subwoofer and remove the speaker wire.
5) Lay the box flat to make it easier to work with. Tear off a sensible amount of polyfill stuffing into a strip.
6) Place it inside the box at the bottom bedding it down. Depending on what kind of sound you want to achieve you will have to experiment with different amounts because with this stuff there is no right or wrong answer.
7) Attach the speaker wires back onto the sub and place it back into the box. Take the box back into the car and connect it to the amp. Play something bass heavy to test out if you like the sound, if you are not happy with it, however there is a small noticeable improvement then you will need to add more stuffing. If you are happy with the sound then take the sub box back in. You will now need to glue it down onto the wood because if you don't it will be flying around inside the box due to all the air movement and it can get stuck inside the spider or voice coil.
8) To finish off installing the polyfill into the sub box you will need to remove it from the box. Get carpet glue adhesive and spray into onto the inside MDF wood of the box were you want to place the stuffing. Once you have applied the glue, place it directly ontop of it and pat it down. Please allow the glue to dry for at least 24 hours before use.
