    This is my first post, however I have been on this forum as a visitor for a long time.

    It's very simple to fix the booming bass problem all you need to do is to go to a car stereo shop and ask them, to put a capacitor on both the doors (of the driver and passenger side between the low and middle range speakers), to cut the low frequencies. You wont miss a thing and you will have the problem fixed.

    I have been around in this forum for quite a while, I finally decided to post my experiences with my Sequoia LTD.

    I hear lot of issues on how people have been treated badly for one reason or the other, I strongly feel that, It takes two to tango.

    I strongly suggest that you guys should look for ways to develop long lasting relationships with your sales people, service manager, the write up person and finally with the technician who would work on your vehicle.

    Why do I say that because I am the living proof and I must say that I have never been refused for any thing that, I have ever asked at the dealership. they go out of their way to facilitate my requests.

    You all will be amazed as to what has been done to my Sequoia free of charge. I never whine and go to the service people with the negative attitude,and that is If there is an issue with the car It can be dealt with.

    You have to take into account that the service people are at the recieving end of it,and I tell you folks that sometimes a simple genuine thank you goes a long way.

    Remember them during the holidays as I do, Show them that you care about their feelings. I call the owner about my pleasent visits to the dealerships. and my comments get passed onto the techs.

    On the lighter side of it, I have 6700 beautiful miles on it without any complaints. I have installed anew top of the line pioneer cd system,a PS2,cd changer, a VCR, two 12 inch Sharp flat panel high def TVs and Sony head phones for my two kids.

    Sharp TVs are instaled on the backs of the front row seats. I plan on adding a roaming satellite antenna this spring. I upgraded my tires to Michelins and yes the Toyota Distt Manager sent me check for 750 dollars to help defray the costs.

    All the plastic panels and carpet and seats were pulled out, Sothat I could quadruple or quintuple the sound deadening material on the chasis and all the plastic panels.that also include all the doors.

    I also added around four inch thick sound insulation in the engine area as well. The pleasure driving my Sequoia is heavenly, To complement the interior further two inch thick pile sheep skins from Newzealand are also added.

    Exterior add ons have been a Go rihno brush gaurd and a nerf bar along with a set of four PIAA Fog lights and driving lights, All the fluids have also been changed to fully synthetics.

    using a capacitor as a crossover filter to can bass is pretty severe... if cheap... because you will lose everything below 500 Hz with something in the 5-20 mF range, depending on speaker impedance rating. you might get the same result by just pulling the wire to the woofers.

    I would tend to agree with the following post, using additional sound treatment to tune the enclosures (doors) away from the resonance of the speaker cone. I have not ridden in a sequoia, but it sounds like a description of a bad case of bass doubling, which is real common in cars, as well as flexibility in some panel that causes it to resonate at about the same frequency as the speaker cone/suspension system.

    doubling (your speaker cannot generate the 100 Hz tone the amplifier is passing, but it can vibrate at 200 Hz, so it does so, putting a phony note in the music) is a cheap trick used to pretend there is more bass in a system than there is. It requires good damping in the enclosure generally to prevent a resonance hangover that artificially generates an abnormally large volume of sound at that fake frequency. bracing and sound dampening are places the manufacturing team shave nickels out of each car part as a matter of course to get the profit up, so even if it worked in the prototypes, it won't in the production model.

    add a block of dense but flexible foam behind each of the speakers in the door panels and see if things get better.
