If you want to learn about how to get only bass from your car subwoofers, you will need to enable the low pass filter on your amplifier that is connected. This is a feature that all two, four and mono block style amplifiers come with. It basically can be adjusted to filter out all of the high range frequencies usually from 80 HZ and above. This is what stops the vocals or voice playing and coming through your car subwoofer. This will make a noticeable difference it terms of making the bass sound tighter and louder right away. Subwoofers are not designed to play vocals due to their large cone surface area they can play up to 120 HZ then they start to roll off because the cone is heavy and they are made for pushing large amounts of air. Thats when the midrange speakers and tweeters take over the rest of the vocal sound frequency spectrum. If you have an aftermarket headunit thats fairly new, it will also have its own low pass filter settings.
To ensure that that vocals are defiantly stopped from coming out of the subwoofer, its best to set it on both the car stereo headunit and the amplifier. All you need to do is go into the audio settings, select the LPF option and set it to 80 HZ. You can also set it around 60 Hz, but it all depends on the music you listen to. Rap sounds the best on 80HZ because it provides that extra bass boost boom and tightness, making the bass sound more louder and you can feel it better as well. This LPF setting works the best for both large ported and sealed box designs.
1) Play a favourite track from a CD of yours that is inserted into the car radio.
2) Pop the trunk and find were your car amplifier is mounted onto, preferably onto the back of the rear seats or the carpeted MDF subwoofer enclosure box.
3) Locate the LPF car amplifier setting, its usually an turnable dial that you can adjust using a flat head screwdriver and ensure that it is turned on by the switch. Adjust it to around 80HZ, but just don't go by the numbers adjust it to how you like it to sound. You will notice right away that the low pass filter crossover has blocked out the vocal and treble coming through the subwoofer improving bass response immediately.

Great Post! I have a JL Microsub+ which has its own amp and LPF built in on a dial, I set it to the lowest level (50hz) but was still getting some vocals and "slight muddyness" (Only noticeable when listening to the sub's with no other speakers on).
ReplyDeleteI then addedd another LPF on the Head unit at 160hz, this cleaned everything up and now i get low tight bass only. So I will always use two filters from now on :)
