extra speakers!

Im thinking about putting 2 extra speakers in my Jeep. I have the 2 up front and 2 in the sound bar and am looking to put 2 more in the rear behind where the seat goes. I custom built a sub box and might make 2 boxes that would go on top or to the side of it with speakers in em. Now the real question would be how to wire these babies up.... I'm pretty slow when it comes to wiring up speakers and what not and what would actually be the proper way of doing it. I could get it to work, but I would expect some sort of small fire or explosion. anyways anyone do something similar and have some ideas for a guy??!! excellent thanks!
All the dude wanted was his rug back.

I'm just a big, hairy, American winnin' machine!

You can add two additional speakers to your system if you do so in series with two others (most obvious would be the two in the sound bar). Wiring them in series will result in a drop in sound level due to the increase in resistance unless you use a lower impedance speaker.

For example, if your current speakers are 8 Ohms then the total impedance after adding two more speakers will be 16 Ohms per run (assuming a four channel receiver) cutting power by half. If you move to a 4 Ohm speaker then it will remain at the current 8 Ohms but then you will need to replace the speakers in the Sound Bar.

Do not wire them in parallel as this will only cause your amplifier to work twice as hard and that will likely generate more heat shortening its life.

Hope that helps.


But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. James 3:17 (KJV)

My suggestion is get an external amplifier for the new speakers or get all new speakers with an external amplifier...

I had a 99 wrangler and had a custom sub box build that fit between the door and backseat in the back with 2 down firing 10s and then had a custom build box to run across the top to the sub box with 2 6x9s and added a 200 watt amp to push the 6x9s and it gave me enough power and great sound even with the top off
