Need help setting gains and HPF's.

[99xtremedime]

Well I finally got the rest of my RF equipment in; I went with teh Power 4x6's, Power 6.5" comp. set, and a Punch P400-4. Im comfortable with the comp set (except for where to set my high pass filter...reccomendations?), but all my questions are in the 4x6's.... I put them in a few weeks ago (off the HU) and they sound AMAZING with crisp clear highs except that they distort from the bass if I turn it up past 17-20ish.... what should I set my High pass frequency at? The frequency response on them are 75-22,000 but I still thik 75 would be too low so I was thinking set it around 100ish?? And also the 4 by's are rated at 45W RMS and my amp does 74W RMS x4 @ 4ohms so whereabouts should I set teh gain at? If you need any other specs or anything let me know. And thanks!

TTT.

Nobody has any suggestions or even any personal preferences for me to start at?

Regardless of the speaker size, turn the high pass all of the way up, turn the volume to a point you would if you wanted to really crank it (i.e. Where the highs begin to distort) and back the high pass crossover down to a level where the amount of bass coming out is what you want and they don't distort. Every system is different, unfortunately you have to use your ears to adjust to you liking and volume limits...

very true i usually just hear it and adjust it from there

Yep, run it loud and set it where its sounds good and clean

The main question has to be are you talking about setting the H.P.F. on the h/u or the 4 channel amp? Reason why i ask is theres different ways of adjusting the filters

depending on the h/u you are using.. The H.P.F. cuts off the bass and adds treble as opposed to the L.P.F were it cuts out treble and adds bass.. So theres so

many ways to go about tuning and setting gains that you basically cannot overdrive the speakers by adding too much bass which will then lead to distortion.

If you going to turn off the H.P.F. on the amp and adjust it from the headunit (Im assuming your amp has H.P.F and L.P.F.) then id recomended setting the bass gains

real low especially if the speakers only handle 45 watts id put the gains anywere from less than 1/3 of the gain. Set the H.P.F from the headunit to 80 for the 4x6s

and another question I didnt mention is how many watts do the comps handle? If its anywere to a 100 watts rms id put the H.P.F frequency from 100 to 110 no more than 120.

Also set the gains on the 4 channel amp a lil less than halfway depending what the comps puts out at 4ohms it should be safe. Another thing will play a key role if your looking

for clearity is having slope adjustments. This is something were equalizers/processors come into play and its just a whole another ball game from their.

Hope this helps.. Any questions im here..

I will be adjusting the HPF from the Amp. My HU is pretty crappy and doesnt have HPF's or LPF's. So with that said should I just turn the volume at the max that it will be played at, and set my HPF's for both channels from there to where it sound the way I want as recommended by the others, or do you recommend another way? I will be upgrading to a Pioneer AVH-P5200DVD when it comes out but Pioneer still hasnt released it... it has AMAZING adjustability so that will help me as well.

Oh and the Comps handle 100W RMS.

Correct. Its always best to adjust the sound that suits your taste from having a good ear. I would turn the volume up from the headunit to whatever vol level sounds like you hear

distortion and from their set the H.P.F. to anywere from 120 to 160 no higher than 200 for the comps. For the 4x6's try setting the crossover a lil lower than 80.

Also since your setting the filters through the amp this means you can adjust your bass gains a lil higher. maybe in between the halfway mark should do for the comps. For the 4x6 speakers set those gains a lil lower. Reading the specs on that amp you should be good setting the gains halfway for the front comps (or a lil bit pass halfway) since it puts out 50watts at 4 Ohms rms.

You just never wanna overdrive your speakers thru too much bass.

continuous power 50W x 4 @ 4-Ohms RMS

100W x 4 @ 2-Ohms RMS

200W x 2 @ 4-Ohms bridged RMS

Ok will do, thanks for all the help. And being a rockford product the amp does way more then rated power @ 74W x 4 @ 4 ohms.
