You are approaching the cutoff level and getting distortion.
You you have too much amplification or too strong of input signal.

You can can turn down compression or turn up attenuation on the receiver and check other Dolby or neo settings from your manual. Or, don't turn it so loud.

Volume goes up by itself


First, check your software firmware version and see if there is an update. If available read your manual how to do a firmware update using your USB port, if you don't have a manual, check Bose.com for their online manual and firmware updates. I had a different problem but the firmware update solved it. Another tip to increase the depth of your bass, while doing the adaptiq process, cover your bass speaker with a pillow, this will make your bass more deeper. You need a second person to cover your bass module with a pillow. in this way, the adaptiq process cannot hear the bass sound and it will increase the bass. You might need to do this several times until you get the desired bass sound. If you have not setup using adaptiq, your better off not using adaptiq, the sound is much better. Hope this helps.

How do i calibrate my powered subwoofer for my car


OK assuming you are referring to after market sub and amp whether or not added to factory head unit (stereo). #1 start your engine, and have your amp adjusting knobs accessible #2 insert a CD of the most listened to type of music (Rock,rap,classic) #3 adjust your stereo volume to YOUR max preferred db level with your amp levels at the lowest settings possible #4 start by increasing your freq. rang by 2 bands at a time then the same with gain, once you have gotten your bass to the level you like with out distorting or popping try increasing your bass boost (if available) till your preferred sound(may need to back off gain and freq. add bass boost accordingly until you like what you hear.play around with it for a while make sure you do this at the peak volume in which YOU listen to music because if you do it at a low volume and then turn it up you can blow your equipment . side not 8''in is for very fast bass reps, 10''in is for average rock and 12''s 15''s 22''s are for your low long deep bass reps such as rap and R&B anything else just e-mail me

Is it possible to hook up 2-6x9 and 2-12in.subs to the 7540a and still pack a nice punch


yes it is however the hookup for it requires something a bit unorthodox

you have 4 outputs (bridgeable)

channel 1 and 2 must be bridged (to lower the ohms) then connected to the 2 6X9 in Parallel..
this must then be set to the high pass frequency (eliminates bass)
lower all the settings as low as possible then turn them up slightly to increase volume to a level where its the hardest and clean sounding..lower volume after

this eliminates the bass and keeps the 6x9 pushing your mid range and high range frequency

now you have 2 channels remaining,, set 3 and 4 to low pass and connect each 12" to an individual channel. (this keeps the bass and ohms high so you will get a clean bass to match with mids and high's. Dont set or bridge for a low bass as it will jam out the 6x9 and your music will sound terrible.

so there u have a simple hookup that will work and keep you sounding clean. remember not to raise the volume on the 6X9 too much as you will blow them..

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!!

The volume on our E67 series tv will not go past a certain level. how can i fix that?


It is true that you won't start to hear this television's volume increasing until the volume level passes 10. Then it gets louder until the volume level gets to 30 then between 30 and 60 it doesn't get any louder. This is the nature of this particular television. You can go into the audio category of the menu and increase the treble and the bass. Listen to the television with surround on and then off to see which one is louder. Connect the television to a sound bar.

After a television is a year or two old it may start to degrade naturally so you might benefit from being walked through an INIT. Call 877-332-7867 to be walked through one and the television may sound louder after it is complete.

When I do a noise test I get no sound out of the woofer. I am getting no bass from the woofer


These are "decent" quality 5.1 speakers, usually without any trouble.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect but bass should be hear. Please switvh power off to the speakers and disconnect all cables from spaekers and connect them for best quality as follows:

1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box, control pod is just cable connection to it
3. Connect all cables to they respective speakers

Establish location of the speakers, from experience, in ideal world:

1. Sub should be on about your knee level or below, about twice your hight from you.
2. Front centre speaker should be about some distance as sub or bit closer on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not while you are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

After speakers are connected:
1. Plug power cord in,
2. Turn all sounds totally down, including subwoofer
3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre speaker, then on sides front speakers till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

Marantz SR 4003, Cables in right place.PEAK light on?Help!


Disconnect your speaker wires at the receiver,then test if it does not "peak" the receiver is fine and you need to check each speaker wire. re-connect one speaker at a time and test until it peaks. then disconnect at speaker and test again. if it peaks, it's a bad wire, if it does not, check the speaker, meter it for a short. If you still need help, post a comment and I can help you some more.

Usually an 800 watt peak sub would be a 400 watt rms. Hmmmm. Anyway, just bridge the amp (1x 380) nd keep the gain up enough to stay clean. Watch the sub and turn up gain until it starts to distort, then back it down a hair. Do this with the CD players volume up 2/3 to 3/4 volume with the BASS and treble at zero (bass better at minus 4 or so if you are a bass head! Hope thishelps.

Overall volume when burned to disc is too low


This is a pretty common complaint and not unique to the 2488. The basic idea is that commercial CDs get their superior volume levels through the use of lots of compression which occurs throughout the mixing and mastering process. There are lots of schools of thought on how and when to apply compression during the production of recordings and the only real way to learn is to read up on compression and then to experiment.

Having said that, volume can also be increased by normalizing but many people don't consider that to be a completely legitimate way to increase dynamics and it does require working with wav files on a PC as opposed to the 2488.

I use a combination of external compressors, software applications, and the 2488 onboard compression effects when mixing/mastering (but mostly ouboard compressors). I usually don't burn CDs from the 2488 and choose to instead tweak the final mixes from the 2488 on my PC using various programs which gives me better control over various parameters (such as applying normalization to all tracks at once).

So the short answer is that there a lots of different ways to get there but basically when the dynamic range or your recorded material is large, the main volume of a track is going to sound lower because the parts with the highest levels (peaks) are going to need to fit in the -0 db area in order not to clip. When compression is applied the dynamic range is squashed down so that the peaks are brought more in line with the audio level which makes up the main portion of the track (in the middle of the dynamic range). This then allows the overall levels to be brought up higher without the peaks clipping. This is called downward compression.

Compressors can also be used to bring up the levels of low volume sounds without affecting the middle and higher level audio. This is called upward compression and also compresses the dynamic range in order to raise the volume of lower levels audio. This is called upward compression.

So when compressing and then boosting the main levels, the noise floor can come up with it. That is why gating is also commonly used along with compression and most outboard compressors are gates as well.

Hope this helps.

Bass sounds flat when volume is increased


probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
