sound deadening

That's more than an octave of sound. That's a lot of missing music.

If you have access to a piano or keyboard, hit one note, then count 13 keys and hit that key. It's a huge difference.

You're going to notice a heck of a difference by doing so. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I will definately be setting the front comps to 80hz now, while it remains on HP, by doing so my mids wont receive alot of bass right?

Pretty much Im trying to understand the whole HP,LP off crossover thing set on the amp. By setting your amp to HP, your giving your speakers mainly high freq, and by setting it on LP, low freq and off pretty much both of them, but I need to read more about this because it seems im missing out on alot of freq, while I go and read about it if soemone could sum it up quick that would be nice.

Your mids will be operating within their designed specifications.

Here's a quick breakdown of the types of pass filters:

LPF = Low Pass Filter

...only allows frequencies LOWER than the cutoff point to pass.

example: Sub amp LPF set to 80Hz. Only 80Hz and lower will be sent to the sub.

HPF = High Pass Filter

...only allows frequencies HIGHER than the cutoff point to pass.

example: Comp amp HPF set to 80Hz. Only 80Hz and higher will be sent to the comps.

BPF = Band Pass Filter

...combination of HPF and LPF to allow only a determined frequency BAND to pass.

example: Band pass filter set for hpf 80Hz and lpf 4000Hz. Only frequencies between 80-4000Hz will be sent.

That's it in a nutshell, but it's not that cut and dry. Things like the cutoff slope need to be factored in, as well.

Wow okay so with having my comps set to 200hz, Im missing out on frq from 80hz-199hz... yeah thats quite a gap.

Usually I listen to a variety of music but sometimes I like to listen to a deep bass song where I turn the bass on the HU to +4(+6 is max) so in theory the mids would receive these freq more right?

It should be okay to use some bass boost for them.

Also.....

Your 5900IB HU has 3 sets of Preouts (Front, Rear, and Sub) and has individual sub boost control built in. Are you using this feature? See page 23 of your user's manual.

yes I am using all 3 rca connections. Im not sure what feature your speaking of. I dont have the user manual with me right now, maybe the website has it so I can download it to see what your talking about.

I was told to never use loudness, or to use the HPF in my head unit...

 

[krisfnbz 10+ year member]

I see what your saying now, I have been using the sub controls all of them except the 50hz, 63hz 80hz 100hz 125hz etc one.

You shouldn't need to mess with the HU's HPF for the interior speakers since you already have a HPF on your amp. The HU's LPF for the subwoofer control is a different story. Since you have the sub amps LPF set to 80Hz, just set the HU's built-in sub LPF to 80Hz or greater and then use the sub boost feature (0 to +6) to adjust the sub volume.

When a system is ideally imaged, you shouldn't have to ever use any EQ'ing on the HU. Doesn't mean you can't. Go for it and tune it to your own likings.
