Overview Details Customer Reviews Category Info Our take on the American International S-25A by Buck Pomerantz The American International S-25A noise filter helps 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-25A noise filter is recommended for audio components rated up to a total of 25 amps and 350 watts. Mounting hardware is included. Warranty: 30 days.

We stay on top of new products and technologies to help people make informed choices. Features Overview: This unit eliminates engine noise coming through the power source. Noise can also enter through the antenna, which is not handled by this unit but which requires an antenna noise filter. Since many vehicles have both problems they could require both this unit and an antenna noise filter. Note: For noise entering through the antenna, you should install an Antenna Noise Filter (see item # 003AS100). Installation: To screw mount the unit, you first remove the mounting plate from the bottom of the unit (wiring instructions appear on the unit under the mounting plate). Secure the mounting plate using the supplied screws, and snap the noise filter onto the mounting plate. To use the strap mount, you snap the mounting plate (B side out) onto the unit's bottom, insert the included tie, and secure. The filter should be kept as close to the radio as possible. Wiring: Black wire = Ground, Blue wire = Positive, Red wire = + 12 Volt.

Crutchfield Customer Review The reviewer purchased this item from us, verified by the email address on the order. I'd been satisfied with Crutchfield purchases before and this time is no different. I had just put a new 383 small block with high performance ignition in my 1968 Camaro convertible and when I fired it up the first time I was thrilled how well the car ran but the audio system had the most horrible engine noise. A quick and easy 3 wire installation of this noise filter in the power wire to the head unit eliminated 90% of the noise. I bought 2 and installrd the second noise filter in the power wire to the amplifier in the trunk. Now all engine noise has been eliminated. Great piece of equipment...inexpensive and simple to install...took all of 15 minutes for each filter. 8 out of 8 people found this helpful Was this review helpful?

Crutchfield Customer Review The reviewer purchased this item from us, verified by the email address on the order. This unit is a bit larger than I thought it would be, but I still found room under the crowded dash of my Jeep Grand Cherokee (wedged in between the radio area and the gauge console). As far as I can tell it's working. I suppose I'd buy it for another car if needed. 2 out of 4 people found this helpful Was this review helpful? Yes | No 2 out of 5 no real difference Written By Bake, Lexington, KY on Monday, April 02, 2012 Probably not the product's fault, but this must not have been what my system needed because there is no discernible difference. So, just because your system has a high frequency whine that changes with engine speed, this may not be the answer. I coupled it with the PAC SNI-1 unit - and it apparently is not what my system needs (i.e., inexpensive Pioneer receiver, clarion 7-band equalizer, 4-channel amplifier, four 2-way 6.5" pioneer speakers in an old Corvette).
