Now what most people do is forget about setting up the crossover settings on a amplifier that is designed for a car subwoofer. This has a huge impact on how well your car subwoofer will perform, in proper settings will not make your subwoofer play louder and deep. Now let me first of all explain how a crossover works briefly. Its an internal feature on any compatible subwoofer amplifier that filters out certain frequencies across the range. You want your subwoofer to only play bass and stop vocals or any kind of treble coming out of it. This make your subwoofer perform better on music as it will only concentrate on producing bass and nothing else.

Now we have experimented with different crossover frequencies over the years and the best is setting the low pass filter to around 80HZ. This makes your car subwoofer play all the deep bass and still being loud at the same time having the punch kick feeling. Setting it too low will loose spl and too high will make it sound boomy with no depth. A low pass filter also known as a LPF to some is used to make the amp send out bass only that its job. The treble is controlled by a different amp for the mids and highs fitted into the front and rear doors. If you are stuck with how to setup the crossover settings on your car amplifier for your subwoofer don't worry we have constructed them for you in the most simplest way possible.
1) Play a bass heavy song such as lil jon, Young jeezy or E40 something with strong bass.
2) Head back to the trunk and find the amplifier location that is powering your car subwoofer.
3) Look for the switch that says 'LPF' or low pass filter. What you want to do is turn this on.
4) Now that you have switched it on there should be an adjustable dial that says LPF. This is what controls the frequency that amplifier can be tuned for the best possible sound towards your music.
5) Get a flat head screwdriver and adjust it around 80 HZ. Increase or decrease it slightly depending on how you like to sound. As every car speaker is different and responds differently due to the nature of the sealed or ported box and material it is made from.
