Horrible FM interference after Basslink install

[5.0 Hatch]

I installed a Infinity Basslink II this weekend in my 08 Civic SI. Basically i ran a power wire, gave it a good ground (seatbelt anchors) and took the high level speaker signal from my factory sub. Now my problem is that all my FM radio stations are fuzzy and distorts really bad on the bass notes in all my speakers; not just the sub. Is it possibly because i'm using the speaker level inputs on the basslink? should i try a LOC?

1. a seat bolt is NOT A GOOD GROUND.. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

- make sure you take the ground to a good spot on the chassis, remove all paint till it's a nice shiny bare metal. then use a self tap screw with star washer's to insure a good ground

2. you need to find signal before amplifacation. the signal you picked up is being amplified by the factory amp, causeing a bad signal..

pick up the signal before amplifacation...
