[QUOTE=ophthos;10199048]So I spent the afternoon fishing wires, measuring length, and planning the layout of my stereo system. I got a package deal from Retrsound with head unit, dual voice coil premium dash speaker, kick panels with premium speakers, and Quadraphonic 4 channel amp. The Amp is going in the trunk A few questions:
1) I read that running your speaker wire and a power source is OK, I also read it will cause interference. I already ran the speaker wire from the trunk along the PS rocker well along with an 18 G wire that goes to a switched source and taped them all together. Will I have an issue
? I can pull the power wire out and re-run it but I've already wrapped the wires with loom tape.
I ran the speaker wires down the passenger side and the power to the amp in the trunk down the driver's side.
2) I also have to run a power feed from the amp directly to the battery. This wire (supplied from Retrosound) has a built in 15 amp fuse. Should I drill a hole in the firewall and run this, or since I have a new wiring loom with modern fuse box, I can tap into a spare constant power wire that has a 15 AMP fuse? Retrosound says to have the fuse within 18" from the battery. Running it directly to the battery isn't an issue, just where do I run it? The PS rocker well has speaker wire in it and I don't have enough cable to go down the DS rocker well. What about running both power lines down the center of the car, under the carpet and the console?
I drilled a hole in the firewall toward the center and up from the steering column. Don't forget to place the grommet in the hole prior to running the wire to protect the wire from fraying. Then I ran the power wire to the battery along with the other wires on the passenger side under the export brace.
I wouldn't run the wires down the middle of the car. If you need to access them, much harder. (ask me how I know!)
