what freq shall i set HP filter to on headunit?

[jason1987]

ive got a pioneer headunit and standard 406 components, ive got my alpine sub set to 80hz, what shall i set the hp filter to for the other speakers? can they handle 80hz?

[Gary406]

my 4 channel amp that powers my 4 music speakers is set to about 100hz

my other 4 channel amp that powers my 2 subs is set just under 100hz

subs set to low pass means everything under 100hz goes to the subwoofers

4 music speakers set to high pass means everything over 100hz goes to them

you want your hz set to the same around 80-100hz but obviously set the high and low pass filters to suit the music/sub speakers

[Gary406]

ye your components handle everything over 100hz,

your head units high pass filter set it to around the same as your subs setting, i just use 100hz

the proper way of setting them up is you want your head unit on full volume setting 1st, turn all amps down , once the volume on the head unit is almost at max you then adjust the input level on the amps,

is 100hz not high for a sub?

[Gary406]

if you ever get stuck mate give us a ring,

07856 431 948

[Gary406]

nah 100hz isnt to high,

my subs have a frequency range of 28hz to 450hz

but some of these frequencys the subs cant play anyway

[jason1987]

ive got an alpine type r in an alpine ported box, ill set it to 100hz tomorrrow and see if it sounds better.

[jason1987]

my headunit lets me set the lp aswell, i dunno which one to use, spose set it to 100 hz on the amp and 100hz on the headunit, if that doesnt mess up the amp settings

[Gary406]

i'll post a pic 2moro of my setup.

but heres a short list

alpine 9855r head unit
JBL GT5 A604E 4 channel amp (for 4 music speakers)
JBL GTO 1004E 4 channel amp (for 2 subs)

2x JBL GTO1202D 12" subwoofers in a double sealed enclosure

Planet Audio Big Bang 6x9s in the shelf
Planet Audio Big Bang 16cm Front Componants

3.5 farad power capacitor

[Gary406]

leave the headunits LPF off if your using an external amp to power the sub

[jason1987]

im just finding the vocals arent as loud as i thought theyd be running off the headunit, prob the sub drowning them out,

[Gary406]

yes that what happens thats why i use a power capacitor and a external amp to power the music speakers

[Gary406]

if you think of it this way its easier to understand,

you have a external amp powering a sub ,

and the head unit powering the music speakers,

the head units small amp cant keep up with an external amplifier, theres no comparison

[Gary406]

so to get right you have to turn the subwoofer down so they all play at the correct level and sound good together

[jason1987]

i just set it all to 100 hz but i cant turn the lpf off on the headunit so i set that to 100hz aswell, and you can adjust the level of the sub on the headunit so you can have the speakers louder or visa versa, i need to get some good components, just need to ger my head round that iso procedure
