ok i installed a pioneer cd/dvd player in my car and i only have the front speakers plugged up...my question is how do i wire up the rear speakers or which wire could i tap into on the amp?

 

I'm guessing you have the factory Bose stereo?

 

yeah

 

Are you running a coaxial or a component plus a tweeter?
Okay coaxial is easier so I will explain that one first--

when you took out the old stock speakers (if you did it yourself) there was 1 wire connected to them. It containted two wires, pretty small, probably 16 gauge. One was power, the other was ground. To replace the stock speaker with a coaxial speaker, it is painfully simple. Take the stock speaker out, put the new speaker in, and connect the power wire to the power terminal on the speaker, and the ground wire with the ground terminal on the speaker.

With a component plus tweeter you will need a crossover. You will use that same wire that you used in the coaxial setup. Incase you were wondering, this is the wire that comes from the headunit. The power line in that goes to the power input in the crossover. The ground line from that wire goes into the ground input in the crossover as well. Then in both the component and the tweeter you have to make wires from the power and ground terminals and connect them to the corresponding terminals in the crossover. The component is usually marked as "woofer" on the crossover. So you will probably see Woofer +, Woofer -, Tweeter +, and Tweeter -. In the end, the crossover should have 6 wires coming out of it, 3 power and 3 ground.

It is usually a good idea to use black wires for ground universally, and red for power generally. if the colors are goofed up and you dont know what is what, trial and error usually works. Hook them up in the + and - terminals and turn the car on and listen to the speakers. Then try reversing them and turn the car back on and try them again and see which sounds better.

---Thats how I wired up my rear speakers. I wired up 6.5 in. Crystal Mobile Sound components and I custom mounted a set of Tweeters right next to them on the back molding behind my head.

 

alrite thanx Srivero297 i'll try this tomorrow

 

If this still doesnt work, then your connection to the headunit is goofed, and you need to check all of the connections you made when hooking up the head unit.

It could be something as simple as a connector not being crimped tightly enough and coming loose when you put everything back together.
