im assuming red to red and black to black? but then what about the extra green and white wires in the iphone cable? where do they go?
Those are the USB wires. For a charger, they need connected through voltage setting resistors.
if you have a multimeter or a volt meter, ascertain the voltage at the amp. If youre interpreting 12V then the fuse for yourchronic furnish is sturdy, if no longer, replace the fuse. Then ascertain you have sturdy grounds (naked metallic, no painted surfaces, secured/bolted tight) If these are ok ascertain your distant cord. Its frequently a skinny blue cord as soon as you purchase the kits. it fairly is the on/off swap. if you have a manufacturing unit radio, then your distant replaced into hooked to an adjunct that good factors 12V at an analogous time as your motor vehicle key turns the upload-ons on (acts as a swap) like a cigarette lighter. If that cord is linked wisely to the amp yet its no longer exhibiting 12V, then its maximum possibly that the fuse for that distinctive accessory is out. replace it. If none of these solves the priority then the priority is with the amp itself. Have it appeared at. despite the fact that it may no longer be the battery because of the actual fact in case your battery replaced into undesirable, it wouldnt influence purely your amp, yet every little thing else on your motor vehicle.
Never assume anything. Wire colours in such cables are not necessarily assigned according to a standard pattern. Before you proceed, find printed documentation -- or its online equivalent -- that clearly and definitively shows the functions of the wires by colour. If all of the wires are for audio (which is possible, but not certain), don't connect any sort of power source to any of them. If it is a USB cable, the red and black are power wires, and the green and white are for digital data. A question was posted about USB wire colours on Y!A about 3 years ago (USB wire color code, please help?). The best answer contains enough info to help you.
