[Chevelle-list] Stereo Wiring

[Crazy Rusty]

Whoever owned my car before me installed a new stereo with a small amp under the passenger seat and a cd changer in the back.  I took out all the carpet so I could get ready for the new stuff I am about to order and found that the wiring is a complete mess.  There are wires going everywhere, at least one of the wires has three splices and four splits.  Not sure why this was done but I am planning on changing it.   These wires (some big, some small) are all running along the passenger side under the door sill plate.  All my other wires running to the back are in the factory spot (running through some flat rubber runner) going front to back in the middle of the drivers side.  Should I route all my wires through that?  I think I will just mount the amp in the back, not sure why it was mounted up front to begin with.   I have seen kickpanels for sale that have speakers but I haven’t seen any that have speakers and astro ventilation.  Anyone know where I could get those?     Once again, thank you for any suggestions, JB
