Need help very confused.

I have a pioneer 3400ub radio I recently installed and I found a pair of polkmono 5 1/4 speakers. I was wondering if I could install those in the rear doors without an amplifier. If I could directly connect those to my unit ???

All you have to do is wire it to wiring harness at the back of the deck. Usually there are 4 spots for speakers on most cars/decks wiring harnesses. Something like purple, green, gray, and white and then their negative wires which have a black strip. Just find the 2 connections you aren't using, find out which is left and which is right then just run your wires and wire (-) to (-) and (+) to (+). But like Bronco said, if you're having problems figuring this out, see if you can get a friend to do it and just watch him so you can learn.

If not using an amplifier you need to connect to the speaker terminals on the power cord, here is an excerpt of your HUs manual:

Those 4 female RCA terminals you see at the right are for use with an amplifier, the signal they carry is to weak to power a speaker. Hope this helps.

Joe ^ gave you a great wiring diagram you can always follow to give you an idea of what you need to do and how to do it. If you want, you can always go to YouTube and watch a How To video on how to install an aftermarket radio and then use that to teach you how to add the speakers. However, the simplest way to do what you're wanting to do is take the (+) and (-) of the 2 back speakers and in the diagram above, add them to the #5 block. That simple
