Interesting-
Some "Loudness" controls do this, too. They boost the upper and lower frequencies at low settings, supposedly to compensate for the perceived loss of bass/treble in the ear at low volumes. As the volume is turned up, the boost is eventually decreased to zero.

There is a VERY noticable drop in bass when increasing volume from 20 to 21.
Most factory radios have some sort of circuit that will cut bass as teh volume increases. This is to reduce the powerful low bass to the small drivers. It is to easy to overdrive with bass at high volumes, so to compensate, the OEM mfg cuts bass to lessen distortion at high volumes.
I too noticed this decrease in bass from 20 to 21, but I have added a couple amps, 4 Boston Acoustic 6.5's and 2 12" subs. I am running about 600 watts continuous (I LOVE MY STEREO!!!) and that "loss" in bass seems to have disappeared. That leaves me to believe that it was in the stock speakers. I would assume that they reproduce treble linear to wattage delivered, but bass does not (unable to produce bass linearly above 20). I have tried to reproduce that dramatic change in bass, but it is completely gone. It is very linear now with the 8 speaker, amplified system. My suggestion....dump the factory squeakers, get Boston Acoustic 6.5's and an alpine MRP-F240. A good all around system.
The stock radio is a PIECE OF CRAP - it was made by Panasonic, who have REALLY CHEAPENED out when it came to this systemrlantigua said:
. The interesting thing is it sounded very ok during the test drive - after the first couple of days though (especially in comparison with the other OEM car audio system such as my Camry JBL system) it just sickens me.Especially the Bass response at any volume level.
So I replaced the front speakers with Pioneer 1671s ($80)(http://www.crutchfield.com/S-AJqSqAilZAA/cgi-bin/ProdView.asp?g=52000&I=130TSA1671) and added a subwoofer (Honda-Kelton OEM) - $300. I could've used an aftermarket subwoofer, but I couldnt find one that had the finish (ie. cant hide it under the passenger seat like the OEM one could) of the OEM one. Overall, I am much more happier with the system now. I might replace the rear speakers as well shortly (they sounded super-sh*tty when I last listened to them when trying to tweak the subwoofer!).
All OE steroes suck. My wife has the upgraded premium sound in her X5 4.4 Sport, and its ok. The Ody touring stereo sucked in my opinion too, just less so than the EXL-RN. It would have still had to have been ripped out. Once you have high end high power, no OE system will ever do. The panasonic head unit in the EXL isn't that bad, for a signal, but the amplification is very poor. Aftermarket amps and speakers will make this excellent. a JL CleanSweep is also a good idea. I went with a lower end converter, but still allows all amplification to be done outside the head unit.6spdtl said:Or just buy a touring

I have the same exact amp and Bostons (6.5") but not the added subwoofer. Overall, the system is 100 times better but I can also say that the bass still drops out at "21." The sound can really get loud if the gains are higher than "normal" but then there is this very very high pitched noise that is heard (as well as a hiss) so I have to leave the gain at just a bit below "normal" and that seems to be fine. The "hiss" and "high pitched noise" is not at all annoying once the music is cranking but to listen to normal talk radio or music at lower levels the background noises were bad.Bennett said:
JoeV... what you are experienceing is likely a ground loop. I am assuming you are using the high power inputs on the alpine? If so, try getting a high to low converter with isolation, it will get rid of the whine. Also, make sure the ground is good on the amp. An easy way to diagnose is to pull the inputs (whethor high or low power inputs to the amp) and listen for it to disappear. It should disappear. If you already have a high to low and the noise is still there, you need to use a better RCA cable (and/or a ground loop isolator). I prefer a non shielded twisted for noise reduction. I had this noise, added the high to low w/ isolation, crystal clear, no alternator whine. It also eliminated the hiss. The hiss is usually from your gains being too high. With a good converter, it wont matter, the alpine is very quiet. I used Stinger Saloc. http://www.stingerelectronics.com/web/prods/electronics.asp
Of course, if you have an extra 170 bucks laying around, the jl cleansweep is excellent.
Also, I would recommend adding some bass. It adds overall depth and allows you to x-over your bostons, letting them really unleash. A Boston G210 with dual 4ohm coils, with an alpine MRP-M350 would be excellent and very balanced.
Good Luck... The 20$ Salocs are extremely easy to install and are well worth the dough.

I concur my 02 Maxima GLE has bose and while way better than honda does cut the bass off after level 20(out of total 31 levels)Bennett said:
So I ripped out the system and gave it to circuit city and installed a full alpine system (got the stuff at crutchfield)I pick it up tommorow I cant wait.

The Alpine Type R component and coaxial speakers and Alpine F345 amp were installed in my 06 Ody last week. It is a huge improvement from the OEM. It is worth every penny. I noticed the buzzing sound at the start of the engine and during ECO kick in. It didn't bother me very much, but I would love to get rid of it. Otherwise, the new Alpine speakers and amp perform without a glitch. It is very crisp and clear.Bennett said:
Bennett, I read your thread somewhere. You cut the VCM and ANC wires of your 05 Ody. Do anyone else cut their VCM and ANC wire?
Do cut the pink and white/green wires at the steering column affect the functionality of the VCM? I'll be glad to get rid of the buzzing sound, but I don't want to loose its overall funtionality. Any ideas?
This is my single biggest complaint on my '07 EX-L. Every other issue is tiny relative to the radio. I drive a Pontiac Grand Prix for almost 10 years with the stock Delco radio, it was was fantastic in comparison to my new van.
It seems to me that the bass does actually decrease as the volume is increased past a certain volume value. Then it seems like the treble really increases relative to the midrange and bass past another value. This is really, really crappy. The balance between bass/midrange/treble changes quite dramatically across the volume range. I hate the way the overall sound get so much more treble at high volumes. Then I have to turn down the treble. But as soon as I decrease volume I have to tune again.
The problem is made even worse because the iPod adapter (USA Spec) is quieter than the FM radio. It seems like the low/mid compression vs. volume is tied to the volume #, not the actual output power. This is also very crappy. I had to crank the volume all the way to 40 to get any decent volume with the windows down today just cruising at 30 mph. Then I had to really crank down the treble.
I do have the OEM subwoofer. It it definitely better than nothing, but still not as good as the two stock 6x9 "subs" in the Pontiac. The Odyssey sub fills in a little bit, but really doesn't provide much punch. It just can't move enough air in the small enclosure.

I don't think it's going to do much for you since the bass cut is coming out of the signal. The sub will still get a reduced signal and the cut will still be noticeable.Marcb said:
If you're really an audiophile, a CleanSweep would be a good first step as mentioned.
