#15-08-44-003: Loud Drone or Growl Noise Heard from Inside Vehicle – (Oct 1, 2015)
Subject: | Loud Drone or Growl Noise Heard from Inside Vehicle |
---|---|
Models: | 2014-2015 Buick Encore |
Equipped with NKC and UQA, or UQG |
Condition
Some customers may comment on a loud drone or growl noise heard from inside the vehicle. The sound may be more predominant during the following scenarios:
- A larger, taller seat occupant in the passenger seat. For example, 300+lb occupant at about 5’10” (178 cm) tall
- A passenger seat occupant with a large bag on lap.
- Passenger compartment is full.
- Rear cargo area is loaded near the sub-woofers location.
Cause
This may be caused by the noise cancelling microphones not functioning as intended.
Replace the amplifier. Refer to Radio Speaker Amplifier Replacement in SI.
Correction
If you encounter a vehicle with the above concern, follow the procedure below.
- Move the passenger seat to the furthest forward position.
- If available, have a taller seat occupant with a bag or backpack in lap sit in the seat.
Note: In this position, the occupants knees will be pressed hard to the glove box.
- With seat occupied, attempt to duplicate the customers concern.
- If duplicated, replace the amplifier. Refer to Radio Speaker Amplifier Replacement in SI.
After the amplifier is replaced, verify the customer’s concern is corrected. If the concern is still present, check connections to the front door speakers, rear door speakers and the sub-woofer for correct polarity.

- Installation - Connect Power/ground to the closest point of chassis of the vehicle. Keep ground wire less than 39” (100 cm) in length. Use 8 gauge or heavier wire. A Mobile Electronics Certified Professional is recommended for installation & safety
- Power - Maximum Power Output of 1100 Watts at 2 Ohms into one channel. Max power output of 550 Watts at 4 Ohms into one Channel. This amplifier is designed to run your subwoofer(s) giving them the power that they need to perform as they were meant to
- High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs. Speaker level inputs will be used to connect the R1100M to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
- Low Level Inputs - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the R1100M with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
- Low Pass Crossover - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
- Wiring Kit - 30 Ft Speaker Wire, 20 ft. 8 GA Red Power Cable, 16 ft. 18 GA Blue Turn-On Wire, 3 ft. 8 GA Black Ground Cable, Competition Quality Fuse Holder with AGU Fuse
- Wiring Kit Continued - 10 5/16" and 1/4" Ring Terminals, 6 ft. Split Loom Tubing, 3 Rubber Grommets, 20 4" Wire Ties, 20 ft. High Performance blue RCA (TRCA) Interconnect
- Amplifier Power - 1100 Watts Max x 1 @2-Ohms, 550 Watts Max x 1 @4-Ohms
- Class A/B Topology - Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal
- Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
- POWER: Maximum Power Output of 1500 Watts at 2 Ohms into one channel. MAX Power Output of 750 Watts at 4 Ohms into one Channel. This amplifier is designed to run your subwoofer(s) giving them the power that they need to perform as they were meant to
- HIGH LEVEL INPUTS: Speaker level inputs are commonly referred to as high-level inputs. Speaker level inputs will be used to connect the AR1500M to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
- LOW LEVEL INPUTS: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the AR1500M with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
- LOW-PASS CROSSOVER: A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
- SWITCHABLE BASS BOOST: Switchable Bass Boost allows you to boost the low bass +18db.
- 1500W Maximum Power Full-Range Amplifier
- Optimized 150-watt RMS output and a max power output of 1500 watts, you can give your music a huge boost in power that will have you and your passengers partying while on the road
- This slim amplifier fits perfectly into any trunk so you can easily connect it to your stereo system
- Power - 4000 Watts Max x 1 @1-Ohm, 2000 Watts Max x 1 @2-Ohms, 1000 Watts Max x 1 @4-Ohms, 8000 Watts Max x 1 @2-Ohms strapped
- MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
- Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
