Using headunit filter vs. amplifier filter

[ckunke002 10+ year member]

My old headunit didn't have any low or hi pass filter options and I just upgraded to one that does. I use the 3 rca preouts to power 1 4 channel amp (my speaker amp) and 1 sub amp. Both amps have their own hi and low pass filters which I use, but is there any benefit from using the ones on the head unit instead? And if I was to use the head unit filters, what would I set the filters at on the amps since they can't be turned off?

if you use the h/u filters turn the ones on the amp off. and vice versa .

and did you ever get the wire?? if it didnt that makes the second MIA package....

The problem is that you can't turn off the amps filters. The sub amp just has the basic lpf like 50 -150 hz and my speaker amp has All pass, low pass and high pass options, you can't really turn it off.

And no, no package :'(

i usually turrn the sub filter all the way up if i use the hu filter (which i do)

and ok good to know. both packages were "lost" so ill try to get together some more for you.

That's really weird, don't even worry about it though, i'll probably just buy some sometime down the road when I upgrade my battery or alt or something lol

i have no idea honestly. i think its because odf the time i sent it (near x-mas) i figured it would just take a while.

The xover section in the HU is usually done by a small DSP which provides digital crossover prior to analog conversion. It is usually more accurate, and gives you a more exact number than turning a nob on an amplifier. I recommend using the HU crossovers.

As for the amps, leave the 4 channel on "all-pass" and turn the frequency on the sub amp all the way up. This will allow the xover points from the HU to take over.
