So i was messing around with my head unit and got to this option called lpf "low pass filter". I have pioneer front door speakers and stock back ones with a single 4 ohm pioneer sub and bazooka amp. My question is what should i set the head unit lpf too. THe options are 80/120/160/through hz. Thanks.

 

Set it to what sounds best, but turn off the x-over on the amp, [set to full-range]. 94

 

63 works for me.

 

Set it pretty close to what you have your sub amp set to. You want the sub to play maybe 100 and below, and the other speakers to pick up everything above.

Sucks that yours jumps from 80 to 120. Why is there even 160 available? You'll probably end up setting it to 80, but as fcm alluded to, trust your ears, not the internet.

You only use it if you have a sub. Cut the bass frequencies out from the door speakers and they sound so much better.

 

Where is the low pass filter for, is it for all speakers, or just the sub output?

Id probally put it at 80, cause pretty much anything over 80 is considered mids.

Id go with the low pass filter on the Sub only.

Actually frequencies between 20Hz and 125Hz would be considered sub bass and up to about 500Hz-600Hz would be considered bass, mid-range would be between the 500Hz-600Hz to around 12kHz and highs to 20kHz. 94

 

Below 20hz is where the good stuff is. How could you leave that out?

And we, as humans, feel frequencies between 1Hz and ~120Hz. Feeling the music greatly adds to the experience.

 

As mentioned if you use the crossover in the deck make sure the one on the amplifier is off or set to full range.

 

i have a pioneer 6500 and boston speakers all around with a cheap ($40) sub setup

i set my amp to full range and set my lpf to 125 so it will hit the higher bass notes. my 6500 doesnt offer the 160 so i would set to to 120 or 160.
i keep the hpf set at either 80 or 125 and everything sounds good

prolly going to upgrade the full range boston subs because i like to hear the full range of the bass guitar for rock music

Sound is subjective but here is why you would not want to do that.

Sub bass is omni-directional. This means that it doesn't really matter where you place a subwoofer because you can't spacially tell where that sound is comming from.

Bass notes and higher are not omni-directional the higher you go up in frequency the easier it is to pin point where that sound is comming from. If you have full range subs (which I have never heard of) and you place the woofer in the rear of your car it will sound funny. JMO
