ground your rcas. wrap bare wire around the rca outputs on the radio and then screw the other end into one of the screws on the chassis,

I think he means the RCA's on the Pioneer HU.

Pioneer has a history of noisy outputs related to a minor design flaw known as a pico fuse that blows out and makes them noisy.

Theres a thread about it on this site that shows how to solve the problem, might have to search.

i never had a noise issues before i installed the h701. can i just take round terminal end and put them between the the rca and the imput and then ground that wire?

or do hey make a kit or something to ground rca to make it easy?

I had this problem with my 880prs a while back. Just pull your deck out, wrap some stripped speakern wire around the rca connections and run the other end to any screw on the chassis of the deck. I know it sounds pretty ghetto, but it will solve your problem

are you running it on the rca end or do you cut into the wire?

I don't have the hu anymore, but I just ran it around the end of the rca. I wouldn't cut into anything

If you have a toslink output on that HU use that should kill you noise as well
