Get rid of that annoying hum

American International's S-10A noise filter helps to eliminate noise that comes in through the 12-volt power line on your in-dash receiver or signal processor. Installation is simple. You have three wires to connect: one to the power line from the battery, one to the receiver's power line, and one to ground. The S-10A noise filter is recommended for audio components rated up to a total of 10 amps and 150 watts. Mounting hardware is included. Dimensions: 2-13/16"W x 1-1/2"H x 1-7/8"D. Warranty: 1 year.

Features

Engine Noise: Noise, caused by the vehicle's engine, can enter your stereo system in one of two ways: through the power source and through the antenna. This noise increases and decreases with speed. This filter eliminates engine noise coming through the power source.

Note: For noise entering through the antenna, you should install an Antenna Noise Filter (see item # 003AS100).

Multiple Applications: This noise filter (S-10-A) can be used for all audio components in your vehicle, including receivers, equalizers, tape players, CD players, CD changers, or small amplifiers.

Capacity: The S-10A noise filter is recommended for audio components rated up to 10 Amps and 150 watts.

Easy Installation: The filter can be mounted to a flat surface using the supplied mounting screws and mounting plate. You can also mount the filter using the supplied 10" wire tie. The filter features three wires that need to be spliced into the power and ground wires leading to the component. The red wire connects to the fused power wire leading to the radio. The blue wire connects to the power lead of the receiver (or component), and the black wire is connected to ground. The filter is most effective when mounted close to the radio.

Crutchfield Customer Review (What's this?)

I've used other noise suppressors to try and eliminate alternator whine in my system after putting in a Parrot system. Third time was the charm as I wasted money on cheaper suppressors which did not work, but American International S-10A removed all the noise just when I was losing hope.

Pros: worked.

Cons: none

Put a Boss audio stereo on my Harley Heritage. It was picking up a bad hum from the engine. I installed the filter and it removed all unwanted noise.

Crutchfield Customer Review (What's this?)

I purchased this filter for 2 volt noise spikes (Alternator noise) on the 12v on my brake switch. This was causing my Cruise Control to intermittently drop out. These noise spikes were discovered with an oscilloscope. After installing this filter, the noise spikes were gone.

Pros: Excellent passive filter

Cons: None

Works!

Crutchfield Customer Review (What's this?)

It eliminated my engine noise. Works great

Pros: good price easy to install

Cons: most radios have two power sources constant 12v and switched. I was afraid the noise would be coming from the source I didn't filter, but I picked correctly.

Perfect

My radio had a serious problem with engine noise- whining sound that would increase with RPM's. Installed this little guy and problem solved. Just like that.

Pros: Small, affordable.

Cons: None

Crutchfield Customer Review (What's this?)

Installed a 2DIN head unit (GPS, HD TV, DVD, iPhone, Bluetooth, Radio, back-up cameras & etc ) in my Toyota RV Tow vehicle the factory Toyota DVD/Tape/Radio had a whine when accelerating. The new head unit exhibited a similar whine. I ordered two filters, installed one on the 12volt main power non switched feed and a week later the second on the Accessory power feed (ignition/key switched feed) . The accessory key/ignition filter really removed the whine and high pitched engine noise. Simple install, heavy gauge pre-cut wire ready to solder. Include a cable tie and channel on the bottom of the filter for securing the cable tie to some point in your dash.

Pros: simple and it works

Cons: In order to filter the non-switched 12volt and the 12volt ignition accessory feed requires two filters-but that's life if you want to isolate ignition noise

Splendid

Crutchfield Customer Review (What's this?)

Worked like a charm. This saved me from having to tear apart my whole dash looking for "interference" in the electronic components of the car.

Pros: Works. Cheap.

Cons: Bulky.
