Fiesta triple stack stereo upgrade - Static hissing issues

[Davek1995]

Hello all,

First of all, hope your all having a lovely Xmas

I've just installed my new radio using this kit http://www.ebay.co.uk/itm/361463142323?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

I bought a JVC KW-R920BT. Everything connected fine, with the included cables on both the kit and stereo, however I'm getting a very annoying static sound on every source and if the volume is turned down the Speakers hiss

It's only on the right speaker, but doesn't do it all the time. Mainly when a song changes.

Heres a video to the noise

 

 

I'm using the same Speakers as my stock radio. I'm not 100% sure if the problem is due to phone interference, but if it was then I'm screwed. I will try tonight if it is my phone.

Anyone got any ideas?
