Don't know if this is what your hearing but...TSB 02-08-44-016 September, 2002
Subject:Whine, Buzz, Generator Whine, Whine Type Noise Heard on Acceleration (Repair Vehicle Sound System Wiring)
Models: 2003 Chevrolet TrailBlazer
2003 GMC, Envoy
2003 Oldsmobile Bravada
Built Prior to December, 2001
Condition:
Some customers may comment on a buzzing or generator whine-type noise. that emanates from the vehicle speakers with the radio on or off and when the headlights are on. This sound may be altered by changing the IP backlighting intensity (Dimming Function). Or, a noise emanates from the All-Wheel Drive system (if equipped), of 1 to 2 seconds duration during initial acceleration, at 24 km/h (15 mph) or at 48 km/h (30 mph). The generator whine-type noise may be observed at any time, however it is more noticeable when the electrical load on the system is high.
Cause:
The cause of this condition may be EMI interference that is being transmitted to the radio system speakers from within the body wiring harness.
Correction:
To determine which parts to order, you will need to inspect the vehicle. There are four types of audio systems available and three specific service wiring harness assemblies.

GM bulletins are Intended for use by professional technicians,NOT a "do-It-yourselfer . They are written to Inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of vehicle. Property trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the Information.

According to the fine print in the above tsb, there are 2003 tripletts which were built before Dec. 2001. is this possible? When did GM start using generators again? I guess these are the first cars in which GM has installed radios and speakers, how else could they explain a 2003 model car with induced whine or hum noise in speaker wiring. A whine that is more pronounced during periods of heavy electrical load would indicate an inadequate electrical source supply. It appears GM has used pre-high school grads to design the tripletts. Either that or GM is not qualified to produce a drive by wire car yet.Please forgive my whining today. I learn more each day by reading these posts. I do not enjoy reading of the G M fixes to the problems.

Clean driving records I might add. We are in the 45-54 age group.
When we moved to Gilbert from the city of Glendale, the change in zip code dropped our inurance rates $150.00 a year on the same vehicles/ coverage.

#8915 of 18329 3.42 Axle by genemo3

I special ordered a 2003 TB with a 3.42 axle and I have been pleasantly surprised with the gas milage. I've filled up four times and the MPG has been 17.5, 18.5, 17.6, and 18.6. Not bad for a new car and much better than my son's Envoy not equipped with a 3.42 axle. And I certainly don't lack for power, especially living in "flat" Florida.#8916 of 18329 3.42 Axle by genemo3 by pete2002

What type of driving does this involve, that is city versus straight hiway? In city driving, do you have a lot of stop and go or just occasional stop signs and lights? Also, have you noticed at what rpm does you TX shift from 1st to 2nd and 2nd to 3rd? This will help us compare with your model. Thanks.#8917 of 18329 by Stever@Edmunds HOST

Jurassic3k, that looks like a snap from the recent SEMA show in Vegas. Try searching sema.org for accessories if no one here can give you brand specifics.Steve, Host
