I decided to update my fuse box with a J-West box. ( Much nicer) and at the same time install an after market SONY digital radio. I need help with where to locate or "splice"
the new wiring. There is a yellow 12V power wire that supposedly stays on all the time as you dont lose your presets. A red wire that is the 12V "Key On accessory wire" and an Orange/white wire that is an "illumination wire" that dims your new radio lights when the headlights are activated. Where is the best place to attach/splice/locate these wires ? Last time I added an after market radio was pre-digital and just attached the one radio line to the cigarette lead. |

300W RMS, or peak? Or "sound power level"?
Let's see. 300W / 14v ~= 21 amps. (More if the rated power is RMS.) I don't think any of the wires in the car, except for the one from the battery to the starter, are going to last long running 21 amps through them. Hook the amp directly to the battery, and use a wire that is thick enough to handle the current. Also install a fuse within ~18" wire run of the battery on that wire. --DD |
