Check your head unit and read the manual, if it has preamp outputs make sure they are set to "subs" or "woofer"

if you have a stock head unit, that is your problem

You can get an in-line low-pass crossover that will filter out the vocals.

Posted on Mar 03, 2008

If you are using an after market deck then you need to adjust the low pass filter (LPF) for the sub. Make sure it is at 80 or below, on many decks you have both a "rear" and "sub" outputs. Check the back of your deck and see if you plugged it into the rear out, if you did this it would send trough all frequencies where as the sub would send out pure bass. Remember even with the amps LPF on some vocals are still below 80hz so its best to do all the sub controls through your deck. If you have an OEM head unit this will happen unless you get an adapter to filter out the vocals and other audio, a popular one is the MTX Re-Q and should work with all factory head units.

Check your frequency knob and turn it to the lowest possible setting, then turn it up until you here faint vocals in the sub and that is the setting for your sub.

    Try checking your low pass frequency settings. The lower the Hz level (i.e. 50Hz) number means the less high end (i.e. vocals) theat will come through the sub. Turn down your low pass frequency and see if that helps.

What r the best settings for a Power Acoustic PEQ-73 7Band passive eq, electronic crossover, sub woofer level control


Depends on your room, speakers being used, size of sub woofer, amp set up ect.
There is no "best setting" for every application. If that was the case a variable control would not be needed.

Some rooms are boomy, which would lead you to turn down low freq's. Some rooms are very splashy, in which case high will need to come come down. Some rooms are very dead in either lows or highs, in which case those freq's would need to be increased.

To get a baseline on what your rooom is like send some pink noise through your system and analyze it with a RTA. (real Time Analizer) There are free apps you can use on your phone or pro audio products that do a very good job. With pink noise being pushed through the system you will see what freqencies are naturally louder or softer in your room. Then you can adjust that real time on your eq and see the changes.

This will set your room to a flat response, however lots of people don't like that sound and want more punch,growl, or clarity. In that case simply adjust the low, mids or highs to your own listening preference

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp. Page 10 of the manual explains how to adjust the subwoofer output. You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.

You MAY be overdriving the sound card. Near flat should work for vocal, but setting the levels throughout the mixer is important as well as the sound card. You can use the LOW CUT to reduce hum if you have noisy system. Describing balancing the levels is more than I can do here. There are many good videos about mixer setup on YouTube.com. You cannot "fix" problems created by improper levels and noise injected into the system using the EQ.
What is important is to see that all gain controls and faders are around mid range to 70% when operating normally. You should be using BALANCED lines everywhere possible either XLR or TRS cables. ALL interconnected equipment should be powered from the same receptacle or power source INCLUDING all amps and powered speakers. Often users use unbalanced lines from mixers to sound boards and pick up noise or they have the levels set wrong between the mixer and sound board resulting in clipping and distortion or poor signal-to-noise ratio.

How do you set this stuff?


Need more info..
How many amps and their RMS rated power.?
If one amp, how many channels + individual power for each channel?.
Two crossovers set at the same freq.is redundant and likely to cause more problems.
Do the front speakers have their own X-over? whats the X-over point? and what is their freq. response (total) are they separates
Rear speakers same question.
I'll point out that you cant hear below 20Hz unless your a whale and very few instruments go that low except organs and synthasizers.
The subsonic filter merely block the lower harmonics from eating up amp power.
Their is no universal setting. all systems are different, as are cars, interiors, ears, windows up or down, noise floor, etc.
A RTA helps with the basics but you will still have to tune by ear,
Good sound is difficult enough to achieve,
Great sound is trial and error and very time consuming.
Sorry no simple answer here. Find a good installer ,preferably with sound judging experience,
It wont be cheap, but if you have enough money invested in the system, Don't skimp. or all you'll have is bragging rights
Best of luck, Sumthin

600 watt 2 channel power acoustik sterling amp


On your amp, there should be a switch (on the side probably) that has "LP", "HP", and "FULL" or "OFF". This is a switch for the low pass/high pass filter. Switch it to "LP" as this will allow only low frequencies to go to your subs, what you want. If you don't have that switch, go to an audio store or online audio supplier and get either a low pass filter, band pass filter, or a cross-over, and follow the wiring diagram that comes with it to filter out the high frequencies before they get to your subs.

Subs will go off the wall with bass, but not in tune with music.


hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
