I have a car radio Pyramid 1704 MPR that only has one wire for each speaker (two total speaker wires). Do I connect the (+) and (-) to the single wire?

Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

Code on stereo for steering wheel is 0000

run rca cables and a remote wire from your radio to the amp,run a power wire from your battery and attatch a ground to the car ,then hook up the wires and cables to there respective places.

go to say Radio Shack and purchace some Multi cored, (4 -6 core) Co-axial cable, this means you have 4 - 6 "Conductors" and use the shield for all the earths & negative power,. This will give you what you need. At a pinch, you could always get a single core, audio coax, and run 4 of them and tape, or zippy tie, into a bundle.

hope this helps

The pb180 has High Input receptacles on the back end. They are marked High Input and identified as Channels 1&2 left/right, and channels 3&4 left/right. You will need to identify all speaker wires coming from your head unit ( left front +&--) , and so on. You will be sending the speaker wires from the head unit to the pb180's High Inputs. In other words, the front left speaker wires(+&-) from the head unit will go to the High Input Channels 1&2 side, left input of the pb180, and so on, so the speaker wires coming out of the head unit will need to be cut. And LABEL all sets of speaker wires before you cut them! Then on the OUTPUT end of the pb180, you will be sending the wires back to the the respective speaker wires which are going to the speakers. So it's out from head unit to pb180 and out from pb180 to speakers.
Hopefully you have the plugs that Pyramid uses for the speaker wire inputs to the amp. If not you have to get creative, and make up terminals to fit into the input receptacles. Maybe a wire terminal from Radio shack will fit those pins..
Also, if you go on line: Google search "Pyramid auto amps" and click on "SEARCH" (upper right hand) of their Web Page. Plug in your model number like this, pb180, and you'll be able to download the manual for this amp. The manual has a full description of the wiring options.

Hope this was helpful and Good Luck!

from what you have explain you have a no experience to do so get your system installed by an audio installer safety come first and u have no clue for your safety seek a qualified person to do it
