Rca Output Voltages

the component's can be a pain what are they going into1974 ford pinto 4 15" punch Z power punch bd 1001 pioneer DEH-6700

Actaully I investigated this before I bought.  I have a 2002 jeep liberty.  The dash where the tweeters are located just pops right off.  The most difficult part from what I can tell will be running the speaker wire to the door  6.5's and getting the rca's from the hu to the amp under the driver seat.  Driver seat comes out real easy and I ordered the tool for the door panel removal.  Not sure how thats going to go but I don't think it will be that big of a problem.  I'm assuming getting the power cable to the battery won't be that difficult and drilling a hole for the ground no big deal.  Got me a fish tape for the wire pulls and an amp install kit on the way.  Hopefully be the a.m. of the 13th my ears will be bleeding.

One thing with the Kenwood (even my Excelon) it says (in the manual) that the RCA signal can be improved by turning off the built-in amp (it is like saying that the HU like mine will put out less than 4v if the built in amp is on).  So I'm taking the DMM to it as soon as I get home.(1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

I was planning on leaving it on to power the two rear speakers to start.  may replace if does not work well.

Yeah mine is still on and powers the back speakers.  The back sound really low even with the volume at 32 as compared to the fronts running off of the PUNCH AMP.(1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).
