teamace24 Posted April 20, 2012 Report Share Posted April 20, 2012 When im playing my system and i go to the sound settings, theres a window that allows me to change the HPF from 0-50-80-100 to 125. While my bass is hitting and im flipping it from 0 to 125 each setting changes my bass dramatically. When i have it at 125 my bass is no where near as loud as when i put it at 0. When i change it from 0 to 50 it still is loud but a little less than 0, then from 50 to 80 even less bass and so on. I played a rap song that had a 25hz bass line in it and i noticed while my hpf is at 0 that bass line is played by my subs, and when i put the hpf at 125 that bass line is somehow filtered out to where its gone. BY THE HPF? My other setting in the subwoofer settingls is the LPF but that does absolutely nothing when im flipping it from setting to setting while my bass plays. Any thoughts on why or what should i do. I so far just leave it 50 on the hpf since my subs dont like 28hz and down and the 50 setting takes those out while not messing with my 32 plus too much.

Freshman6969 Posted April 20, 2012 Report Share Posted April 20, 2012 you have your rcas mixed up, pull your h/u and put the rcas for the sub amp to the SUB preout, i think on those models its just 1 input for sub if you have the pigtails, so use a y connecter or just use 1 rca Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?

Guest Posted April 20, 2012 Report Share Posted April 20, 2012 (edited) a HPF blocks notes lower than Xhz. which is what a subsonic filter is. edit: you also use a HPF for regular door speakers. unless you're doing bandpass or something, which is another story Edited April 20, 2012 by Kranny Quote Link to comment Share on other sites More sharing options...
teamace24 Posted April 20, 2012 Author Report Share Posted April 20, 2012 Thats whats confusing on other head units the hpf only affected the door speakers but on this one it affects my bass. So my rca's aare mixed up or is this just a subsonic? but then why also have an lpf option? My brother put in the radio a while back but im just now sharing this with smd.

teamace24 Posted April 20, 2012 Author Report Share Posted April 20, 2012 Ok i was reading the hpf has a 12 db slope from setting to setting and the lpf has a 18db slope from setting to setting. So what should i expect when i do fix my rcas right? Specifically with a bass line of 30hz and stuff or will i see no change at all and just will now tweak the lpf setting instead of the hpf like i used to?

Jessica Posted April 20, 2012 Report Share Posted April 20, 2012 You should expect to get a a lot less vocals and midbass in your subs when you use your LPF properly. You might want to see if your amp has an lpf and if it is enabled. Where you set it just depends on things like your musical tastes and what subs you have and the enclosure they are in. Whatever you do i think 80hz is a good starting point for an lpf and then adjust down from there. Quote Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

teamace24 Posted April 20, 2012 Author Report Share Posted April 20, 2012 I have everything setup right as far as my amps i know how to tweak them and yes the lpf is used on my bass amp. It was just a weird situation i was writing about how my headunits hpf was allowing and filtering bass when its always the lpf handling that and not the hpf which is for the vocals and highs. Im going to checj the rcas and hopefully they were put wrong if not ill be pretty lost.
