Gentlemen,

I am in the process of installing a 4 channel amp in my 1999 Ford Ranger 4x4 extended cab. The purpose of wiring this amp is to power all 4 after market door spears inside the truck. Initially I had planned to use new speaker cable to all 4 speakers. Upon actually trying to run the wire I have pretty much given up. It's a huge pain in the rear to route the wire through the factory cable routing.

I have looked all over every ranger forum out there and I can't find this answer. I want to wire it up to the factory speakers. I was wondering if cut the "factory wiring harness to head unit harness" and wire my speakers into the corresponding wires on the factory wiring harness adapter end, will that work?

Again I'm talking about cutting up the head unit to factory adapter and wiring the speaker cables from my amp to the factory wiring harness adaptor that would normally adapt to a pioneer HU. That would in effect do the same thing just use the factory wiring correct?

Once again I appreciate all the help!

 

Yes it will, I did it with my 89 F150 many years ago. The only down side is, the stock wire size will not carry as much current as a larger gauge, so you may have a voltage drop. This shouldn't effect sound quality and be safe to use at reasonable levels.

I think what you are describing is cutting the aftermarket integration harness so you don't have to cut the stock wiring. Yes, that will work just fine.

 

You will not have a problem. Did it with 75x4 on a 2007 F350.
