Re: Screeching with Bass

If it's happening only in one speaker, then the speaker is almost certainly damaged.

I have a pair of linn komponent 104 speakers i was wondering if i can add a sub woofer to my amp to give the sound more bass as the speakers dont have a good bass sound

The Linn's should have a good bass, clean & tight but not boomy. Have you got them correctly phased? Red-to-red, Black-to-black? Bass is killed if one speaker is anti-phased.

I have a system installed and i have mtx speakers plus mtx subwoofers i want to know how could i take the bass of the speakers because it sounds horrible when loud

if you turn the bass setting in your radio down it will take the bass out, but may take some of the bass out of the subs as well, if this occurs and you still are not satified, you either have to get a car receiver with a non fading subwoofer preout, or you could get bass blockers for all the speakers you dont want the bass in

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.

I installed a Pioneer DEH-P800PRS head unit and 4 Kenwood KFC-1662S speakers in my 2003 Dodge Dakota extended cab truck. I used a Kenwood KAC-5204 2 channel amp connected in parallel. Sounds good at lower...

Hello.... sorry to hear about your problem. Bass is the ultimate evil of coaxial speakers. You have a couple of options here, and this is just my professional opinion because I do not know what your lifestyle details, such as truck space needs, type of music you listen to, budget, etc. If you are looking for alot of bass, the best bet would be to use 2 external amplifiers, 1 for the interior speakers, and 1 for a subwoofer. You would then need to purchase an electronic crossover. With this setup, you can remove all of the low frequencies from the coaxial speakers and put them where they belong, with the sub. You will gain EXCEPTIONAL clarity and a very high volume before distortion level. Again it will depend on what your budget is and if you are willing to compromise on some cab space. The only other option you have at this point is if you are wanting to play your music at high volume levels, you will just need to reduce the bass level as you increase volume. I hope this has helped. Good luck with your venture!!

Not gettin enough bass

Hello saini_jatt_2, On the JBL3501 700 watt monoblock, you have adjustments for low pass and a setting for boost marked DBO, allowing you to select and boost the frequencies sent to the subs. If your amp is not the 3501, but a different JBL amp, the settings may be different. Set the LP to either the white dot (about 100Hz) or slightly below to about 80Hz. Set the HP to about midscale or slightly higher. Set the boost to wherever the bass sounds best. One other setting that will affect bass volume is the "input level" or gain control. It should have been properly set by your installer, but you can "tweak" it for best performance. Turning it up increases the sensitivity and matches it with the output from your head unit. Too high will cause distortion. Too low will result in less bass. So you want to set it just to the point that you begin to hear the distortion and then back it off slightly until the distortion disappears. Hope this helps.

What duz level adjustment do


The level control controls the input level coming from your head unit (receiver) to the amp.

Your Sony users manual is a little vague on how to best adjust the level and other controls.

Here is one method that some installers use and works well with most amps.

Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.

Hope this helps.

Dual voice coil speakers

best way to do this to preserve your amp and speaker is to wire the speaker Voice coils in series.

VC1 = Voice coil 1

AMP + to VC1 +
VC1 - to VC2 +
VC2 - to Amp -

Set you amps bass gain down very low. Crank up the volume with a bass test audio track. Turn the switch to LPF or Low pass filter. Adjust a LPF to about 60 hz Adjust the bass gain up until your Sub begins to sound sitorted or choppy. Then tune the bass gain just below where it distorts. Then you are set.

Subwoofer Trouble

Turn the bass gain all the way down., Turn up your your volume on bass test song. Crank up the little box next to the steering wheel wide open . Now go gradually turn up the bass gain on the RF amp until you get distortion. Turn the gain down slightly. Now you can enjoy playing the bass from one end of the little boxes setting to the other without ovrloading your amp and subs. Open a can of whoopass on anyone who tries to crank up on your gain.
