Ive bought some aftermarket mp3 device for my renault clio head unit and it gave me the well known alternator yawning.
Installed the anr1000 = > no noise anymore.
Excellent product.

Green wire: Connect the Green wire to the 12 volt wire coming from the vehicle that you want to filter noise from.
Black wire: Connect the Black wire to chassis ground.
Red wire: Connect the Red wire to the power wire of the part you are installing.

I installed 2 sets of HID lights on my truck but I was getting feedback from them. I installed this noise filter and I have very little or no feedback anymore.

This product does not come with any instructions, but it does the job

Didn't fix my problem, but would have worked if I had not sold my system. Easy to use. First ground wire broke from right inside the casing but Sonic Electronix replaced it free of charge(under warranty). Would recommend it.

Well, I needed to filter and I trusted the metra guys. Works great, just as advertised and its really easy to install, just make sure you read the install guide on the internet because it might be easy to get confused with the 3 wires order but other than that its just great!

I moved my XM radio from my old car to my new one, and had to install a cassette player. It was very noisy and got worse with engine speed. I installed the Axxess ANR1000 and all the electrical engine noise was gone. Great product and easy to install.

It works Great stopped the alternator noise i was getting.

Connections:
Green wire: Connect the Green wire to the 12 volt wire coming from the vehicle that you want to filter noise from.
Black wire: Connect the Black wire to chassis ground.
Red wire: Connect the Red wire to the power wire of the part you are installing.

Since this is ideal to hook up to a deck, its gotta go in the dash. after moving some stuff around it fit snug behind the deck with no room to spare. it does get the job done if you have noise in your line from a bad alt

It didnt work for me .I still have popping crackle noise on FM band!
