• Step 1. Remove the baloney
• Footstep 2. Flatten the signal, open up the low-laissez passer filter
• Step iii. Conform the subwoofer gain and low-pass filter
• Footstep 4. Adjust the bass boost and subsonic filter
• Step v. Lucifer the subwoofer level to the receiver book

I of the things I similar most well-nigh subwoofers is that I tin can feel the musical emotion direct with my body. The low frequency vanquish often forces me to dance around, or, at the very least, nod my head along with the rhythm. That's why we all like music in the get-go identify — it moves us.

It can have a little time and effort to get the exact bass sound you want from your subs, but the rewards of a well-tuned subwoofer system are overwhelmingly cool and physically satisfying.

Earlier we get started...

First, fix your speaker level

Proceed in mind, distortion is the enemy — it destroys speakers, subs, and eardrums. Distortion sounds like crackling, flapping, crunching, or hissing that interferes with the distinct sound of a instrument. If you power your full-range car speakers with an amplifier, it is crucial that the amp's gain is properly prepare to prevent distortion.

[Need an amplifier? Run into our total selection.]

Step 1: Remove the distortion

With the amp gain ready low, play some music and turn up your receiver'due south volume until you hear the music distorting; then dorsum off the volume until the music sounds clean over again. Note or mark where the receiver's volume is. This setting is the maximum volume your receiver can go to and still play cleanly.

Now, turn the amp'south proceeds upwardly until you hear distortion again; so back off the gain slightly until the baloney goes away. The amp gain is now set, so you tin lower the receiver volume to a more comfy level. Even if your speaker system does not have an amplifier, y'all however demand to detect that maximum volume bespeak on your receiver by turning it upwards to only beneath distortion level.

Now y'all're ready for some bass

Pace 2: Flatten the signal, open the low-pass filter

Plough your sub amp'due south gain to its lowest, most counter-clockwise position. Switch its low-pass filter on and set up information technology every bit loftier, clockwise, as it volition go. If it has a bass boost, plow it off. If it has a remote level control, set information technology to its middle position so, later, you have the choice of boosting or cut the bass on an individual song.

Adjust your receiver's bass tone command to its middle, zero, or "flat" setting, whichever it's called on your stereo. If it has a subwoofer level control, set up information technology, too, to its middle, or "no proceeds" setting. Sometimes receivers have a crossover, depression-pass filter, or bass boost on their subwoofer output. Brand sure those are all turned off, too.

Offset by turning the gain down, and turn off your filters and bass boost.

Note: Practise not utilise the low-pass filters, crossovers, or bass boosts on the receiver and the amplifier at the same time. Utilize one or the other, but not both. The reason is that something called phase distortion generates around each filter or boost's crossover frequency, muddying upwards the sound.

Step 3: Conform the subwoofer gain and low-laissez passer filter

Play music through your receiver at about one-quarter volume. Turn upwardly the gain of the subwoofer amp until the sound from your subwoofer completely overpowers the other speakers, without distorting.

Plow the gain upward until it distorts, then back information technology off until the sound is make clean again.

While listening to the music coming out of your sub, slowly accommodate the sub amp's low-pass filter downwards until all the loftier- and mid-frequency notes disappear.

The depression-pass filter eliminates the notes yous don't want your subwoofer to play. Information technology also acts like a tone control to capture the "edges" of the kick pulsate's sound; the attack and release of its boom. Filter out the cymbals, strings, vocals, and guitars. Leave the bass and the low drums.

Stride 4: Bass boost and subsonic filter

If y'all accept a bass boost, endeavour carefully turning it up to hear what the bass drum sounds similar when you do. Applying but a little bass boost will bring upwardly the kick a lot. Be careful with the bass boost, if you choose to apply it — this is where baloney is often introduced into a arrangement. If yous hear baloney, lower the sub amp's gain until information technology goes away. Use the bass heave to feel the trounce in the air your sub moves.

Now play with the bass boost.

For ported subwoofers, use a subsonic filter on your amplifier to tame any overly loud low notes. This will assistance decrease the levels of the notes at which the enclosure resonates. Fine-tune all the filters some more than to make the bass drum sound tight and dry or loose and reverberant, according to your personal taste. I like reggae and soul, then my bass is plenty loud, merely it's a fleck drier than most people might similar.

The important affair is to go along adjusting your system until yous hear something you like. When you're satisfied with the tone of your organisation'due south bass and kick, plow the subwoofer's volume downward as far as yous can, using the subwoofer level in the receiver's sound adjustment menu or the remote bass knob if you have one.

Blending all the frequencies

Now that each slice of the puzzle is fix, information technology'due south fourth dimension to bring all the music into focus.

Footstep 5: Matching the subwoofer level to the receiver volume

Turn up the receiver's volume to its maximum, distortion-costless position. Then slowly plow up the subwoofer volume until the bass sounds balanced with the rest of the music. That should do it.

Run your remote bass boost or level command up and down a niggling to hear what it does. Considering of the size of the acoustic space in a car, subwoofers sometimes don't combine their sound constructively with the rest of a organization'due south sound waves. If your bass has plenty of volume but seems to lack punch, you tin can sometimes assistance it by reversing your sub's speaker leads. This reverses the subwoofer cone's forwards and backward movements, which might put all the sound waves together better than the other way. Whichever way sounds best is the right style.

Troubleshooting any problems

If you hear distortion coming from your subs, plow down the sub amp's gain. If, at this betoken, you cannot get enough bass out of your subwoofer to go along up with the other speakers without distorting, and so you will need to become a bigger subwoofer and amplifier combination, with higher ability-handling abilities.

You shouldn't lower the gain of your full-range amplifier to attempt and match your lack of subwoofer volume. Doing then could allow the amp to send out distorted, clipped signals to your total-range speakers, defeating your goal for make clean, full sound, which is why you put in a subwoofer to begin with. More than power, specially in the bass, is always amend than not having plenty.

Now you lot should be able to relish the robust fullness and beat of your music with your sub tuned up to match your system'south capabilities and your ear's preference. Simply recall to be polite, and plow your blast volume down when it might bother other people.
