Installing an audio system for the first time in 20 years, need some help...

[MTG#10]

Im installing a cheap system in my new (2011 but new to me) F150 because the factory system is garbage. Ive already installed four new door speakers (Infinity 682.11cf) and Im doing the head unit, amp, and sub this weekend.

My head unit is this Jensen, I went with this cheap Boss amp, and this 12" Kicker.

I used to install systems in my own vehicles and my friends' a lot when I was younger so I know what Im doing for the most part but this head unit has something Ive never seen before, a dedicated single sub out plug, a pair of front RCA plugs, and a pair of back RCA plugs.

So how would I go about connecting the head unit to the amp? The amp has normal left and right RCA inputs. Since Im only running one sub, and no amp to my door speakers I'd assume the sub out plug on my head unit is what I'd use but its just one single plug...do they make a converter or would I just plug it into either the right or the left?

Any help/advice appreciated!

The speaker issue hit a nerve, I had one of those ****ers that every wire but 2 were in the wrong hole. Right car on the box and it plugged right in

Also the right rear speaker doesnt work for some unknown reason, it worked just fine with the factory head unit.

The other plug is likely for for option items like a sync, subwoofer, rear seat entertainment, auxiliary devices, etc.

The reason you won't find +12v from the factory radio harness is because the computer/BUS has it ground relay switched internally in the factory radio.

You just need to search out an ignition source with a test light and tap on.

Those pins on the aftermarket harnesses aren't always seated and can get pushed up instead of in.

Man so much has changed in the sound world. I bought speakers online for my BMW and they sucked ass. This after I cut holes in the doors to fit them in.

I gave the car to my son and he had a big ass bass put in the trunk. That was the missing link. Problem is, these audio places don't know how to work with the existing wiring harnesses so he has to put in a ridiculous off brand stereo to get it to work. Didn't work with the steering wheel controls anymore. Dumb.

Think it would have been better to just buy a boom box and put it in the back seat.

Turn on car, and pull fuses until the radio shuts off.

Track wire back to radio and splice.

Ok like I suspected I definitely need another amp for my door speakers.

Looking at this:

Is it ok to tap into the remote wire from my other amp? I'd also like to tap into the power wire too but its only an 8 gauge so Im guessing that probably wouldn't be a good idea...

run a wire to a dual fuse box and then run power to both amps...

I already have my first amp hooked up and its power is running straight to the battery. I'll probably just end up running another one alongside it from my new amp.
