I have brought these speakers, when i turn the headunit up above about 3 quaters of the way they distort, they are running off a 4 channel 4ohm amp with 400watt rms but they do it with the gain on the amp...


If you run the power amp at a very low setting it makes the amp subject to noise and distortion. You want around a 60% setting.

Speakers also need to have proper loading, that is in a cabinet or enclosure that is kind of matched to them. If the amp is rated at a true 400 Watts RMS then the speakers should be at least 800 Watts as they "cheat" on those SPEAKER ratings and MANY A SPEAKER IS BLOWN AS A RESULT.

Is the bass boost the gain or frequency knob?


Bass boost simply adds DB or gain to the bass signal. Some like it, some dont.
The frequency knob is the Low Pass Filter (LPF) that cuts off the amp output above
the set frequency. A bass system usually cuts off below 400 HZ and more often 200HZ.
A good, rattle your car bass note is in the 25-80HZ range or lower but most amps and audio
input devices cant attain a good low note with clarity.
"Low-pass filter allows only frequencies below the crossover point to be amplified. A high-pass filter allows only frequencies above the crossover point to be amplified - useful for keeping low bass away from small speakers, so they can play more efficiently."

I've got a 1999 ford expedition with the Mach radio system in it and it does not have any bass playing thru the front or back speakers and i've changed out the factory amp thats in the back where the sub...


does the new amp you have have a hpf setting if so check to see if thats on, turn off the x-over so it will play both lpf and hpf, bass and treble. are all the speakers wired to the amp aswell, this is the only thing that would stop bass other than the head units settings.

My speakers make almost no sound at max volume. However if you listen closely, the music still plays, its just not amplified. How can i check the amplifier?


if you are wanting bass adjust your amp settings to low pass. if you are wanting a lil bass- a lil treb- adjust your amp to full. and make sure your rca cables are hooked up in the proper spots.

I plugged int he rca's but he the lowest sounding bass possibe


kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.

Installation


Hi JJerky,

I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.


Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.

SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-

SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -

AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -

This should give you a good repsonse.

Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.

Bass amp settings


For rock and slapping you are going to want to set the Bass and Treble controls high and the Mids low. For music such as Jazz you are going to want more mids so that your sound will be fatter. If there is a button marked "Mid-Scoop" you'll want that on when slapping.
