Re: Why do people turn down all the bass and mid frequency's in their doors?
I dunno. Maybe it's because that's how factory systems are setup - all the bass in the rear. Reminds me of the 80's with 6X9's in the rear deck and 3.5's up front

Oddly if you look at home audio speakers many of them cross over the sub near 500 Hz. It's OK if you have a single point source, but not OK if the sub is behind you.
Would it not be better to adjust the mid range and higher frequencies to pick up where the sub leaves off? What is the point in getting awesome component speakers if you don't listen to the mids? I figure that most quality car audio subs will go up to at least 100hz or so, and most quality mid range drivers will go down to at least 100hz. Would that be a pretty safe assumption?
The hipass frequency for main speakers is typically done with the amplifier. External crossovers only handle the mid/tweet transition. Some head units have HPF built in but I like the variability of an analog HPF better. Same is true with the sub LPF, but if I use the sub preouts on my HU I'm forced to choose a LPF setting, so the amp's LPF is turned off.
How would a person go about setting up their door speakers to crossover to their sub(s) at 100h? Do door speakers need an out board crossover? If so, is that cross over adjustable to help better blend the door speakers with th sub(s)? Or is all of this taken care of with the head unit?.
