I have my speakers amped in my car already and I just bought an infinity reference amp to power my clarion sub. Just wondering what I should set for high pass and low pass on my sub. I want the sub to play a bitttt of the low mids as well cause my speakers arn’t that beefy. Low pass goes from 32 to 320 and High pass goes between 20 and 80. No idea what to set it at. Once again mono block 1 channel amp powering a sub. Thanks.
set the amp to low pass filter. high pass would only be used if you were powering coaxial or component speakers. i just looked at my alpine mono and it only has a 20-200hz lpf.
The frequency you set it at really depends on the speaker’s frequency response and at what frequency the response starts to roll off at. Can you post some specs on the sub?
Or if you just want a rough number, go for around 60-100 and see how it sounds.
Thanks guys

There’s no option on my amp to turn off the high pass. Should i set it all the way up or all the way down or something instead?
There are dials for input (volume), hp, lp, boost… however there are no switches to turn anything on or off.
turn the high pass all the way down (20), and the low pass to 100-120hz and start there.
Just did some research. Going to set low pass around 120 so it plays freq 120 and lower and high pass at 40 so it won’t play anything below 40. Seems like a good sub range for me. Thoughts?

I heard in a ported encloser a sub can blow if u turn high pass down too far. Plus I thought anything below like 50 was inaudioable to the ear anyway. Could be bs tho. Plus im a car audio no0b
True, in a ported enclosure sub F3 frequencies can cause excessive travel of the voice-coil/cone and cause damage. If you want to be safe, then put it at 30Hz.
You can hear well below 50Hz, typical audio response starts ~12Hz; but down that low and lower it becomes more a physical vibration response than an audio response.
Hell, my home theater sub has an F3 in the single digits frequency (~9Hz).
(F3 is the frequency where the output of the speaker begins to fall off/reduce).
Awesome. Maybe I’ll lower it down to 30 then.
I’ll just add that the less range you set your sub to reproduce, the better job it will do (the cone can only move in one direction at a time). So play with limiting both ends and the ideal result would be where it rolls in naturally from your mids and goes as low as you can hear but not further.
