[QUOTE="Bunglefuzz, post: 8900548, member: 693702"] I've just bought an "InPhase IPA601" amp. Spec copied below. Due to it's size it's going to have to be mounted in the boot, which means the phono lead to my mobile phone housed in the dash needs to be 4.25 meters long. Will this work, or am I just swapping one problem for another? Should I buy a shielded cable for that length? Many cables that claim to be shielded seem to in fact only be armoured. From what google says, a shielded phono cable should have an encasing metal shield that is then grounded to the body on only one end, and that being the amp side as close to the amp as possible. Or are shielded cables that don't have a separate ground wire still shielded by grounding to the negative contact??? Any layman's advice is so greatly appreciated please. Am I doing this right, or I am fighting to do something that was simply never going to work? Considering the original setup didn't sound too bad I'm thinking with a bit of tweeking it should be ok.
