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 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-15A noise filter is recommended for audio components rated up to 15 Amps and 250 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.

Written By Jimbo, Croton NY on Thursday, February 02, 2012 I was getting a whirring sound through my speakers, while driving, especially while listening to AM radio. It was very easy to install and stopped the noise. Pros: Easy to install, works as advertised. Cons: None Was this review helpful? Yes | No 1 out of 5 Can you solder? Written By Roberto, Houston, TX on Wednesday, January 04, 2012 Needed a noise filter on XM radio plug in - rest of system had no noise. Package was in rough shape - plastic was torn and unit was covered in little white specs and something was obviously loose inside (rattled). Should have returned it - I'm sure Crutchfield would have taken care of it, but based on previous reviews, decided to open it up and found loose transformer - solder joints to board broken and hot glue everywhere (the source of the white specs). Fixed the solder joints, zip-tied back together. Installed and no more noise on XM. So... it (now) works great for me - but construction quality is horrible. Was this review helpful? Yes | No 5 out of 5 Worked great in our race trailer Written By Rhonda, Germantown, OH on Wednesday, September 07, 2011 This little guy did the trick in our race trailer. We had a lot of interference in our 12 volt radio whenever we started the generator. This removed all the humming, static and noise. Great deal and simple to install. Was this review helpful? Yes | No 1 out of 5 American International S-15A Written By Sam, O.C. CA on Thursday, January 20, 2011 I have never written a review regarding an item I purchased, but I felt I had to give a review to this one. Package was fine; product looked fine until I removed it from the package. As mentioned, it did look good, but it rattled and just felt like it was falling apart!!! I opened it up and found that inside electrical piece had come unglued from the case. The solder points were lose and needed to be re-soldered. I had to reapply glue and ziptie the assembly together. Horrible craftsmanship and I cannot believe that Crutchfield caries this. If this is purchased by someone who does not have the knowledge to repair it, it will be returned as it will not function correctly due to bad solders, or it will fail in a short period of time. After the repairs, it did work as advertised though. The alternator whine was gone. Was this review helpful? Yes | No 2 out of 5 American International S-15A Written By PWiz, Marquette, MI on Tuesday, September 28, 2010 Very poor workmanship in pretty package. It didn't work. The device also had a rattle. Had to take it apart and found the glue holding the circuit board had broken loose. Also found a cold solder joint on one of the choke coil leads where it attaches to the pc board. It appears that all of the enamel coating on the copper leads had been poorly cleaned resulting in the cold solder joint. Cleaned up leads and resoldered. Filter now works as expected. 2 out of 2 people found this helpful Was this review helpful? Yes | No 1 out of 5 Worse than nothing. Save your money. Written By Therian, LI, NY on Thursday, April 08, 2010 I've bought a few noise filters over the years and I've never seen one that actually made things worse (until now). There was actually more nose and interference with this filter installed than without it. A complete waste of money and time installing/uninstalling it. I've never been motivated to write an online review before this, I hope I can help keep someone from throwing away their money like I did. 1 out of 2 people found this helpful Was this review helpful? Yes | No 2 out of 5 Didn't do the job Written By uncle buck, Grand Blanc, MI on Thursday, April 01, 2010 I was referred to this product by crutchfield's technical article on how to suppress engine noise. It did not fix the problem on my car. I installed two amps and two subs along with a 4ga power wire and JL audio twisted pair audio cables (not cheap!) along with a kenwood kdc-x792 h/u. upon finishing the installation, I had a horrible high pitched whinning coming through all speakers. following the flow chart for eliminating engine noise, i installed this unit and it did nothing. I found the real problem after searching the internet and found that I needed to ground the low side (shield) of the h/u's pre-out jacks, as well as the chassis of the head unit itself. Once I did this, the noise went away about 90-95%. There was still a hint of whine but could only be heard if the volume was all the way down. It bugged me not because I could here it, but because I knew it was there and if I listened for it I could here it. so I once again connected the noise filter and the remaining noise is gone. so, did it work? sort of. 6 out of 7 people found this helpful Was this review helpful?

This thing made absolutely not difference with the alternator noise coming over my system. I hooked it up and was hoping to clear the whine from the power and it was a total dude.

Yes | No 5 out of 5 Worked great, cheap! Written By Mike, Wichita, KS on Tuesday, June 05, 2007 I purchased this to use in my 2003 Jeep Liberty. I hooked it up to the utility outlet in the dash, which feeds power through a direct hook up to my Sirius head unit, and through a monster plug in cable to my IPOD. Before installation, I was getting definite engine noise. This was worse after I had to replace the Sirius antenna wire and routed it near the utility outlet. After rerouting the antenna lead up by the radio and installing this filter, I cannot hear any engine sounds, even when listening to talk radio on Sirius where the engine noise was very pronounced. Great product, fit easily behind the dash using heavy duty double sided foam tape, took maybe 20 minutes to install. 8 out of 8 people found this helpful Was this review helpful?
