08 Compass Speaker Wiring

bcashjmu · 07-13-2012, 04:36 PM

Hey guys,
I am new to this forum. As the other compass forum hasn't approved me yet for posting. I am installing a powered 8" sub under the front passenger seat. It fits perfectly. However, I need to tap into some speaker wires in order to hook it up. Where would be the easiest place to tap into the right and left +/- cables from the passenger front seat? Also, what color wires am I looking for and what is the best method for tapping into them.
Thanks!

Do you have the Boston factory system by any chance? The amps for those are near the spare tire under rear seat, really easy access. Im not sure if the other system has external amps or if its in the head unit though?

if you're just trying to tap into +- wires off a door speaker, please have a professional wire your sub up. it's going to sound like crap otherwise.

IRSmart...if its a powered sub...it probably has its own amp and crossovers, and likely has speaker level inputs designed for that.

The only fail that might be...is if the factory amp has a high pass crossover to save the factory speakers. Then his new sub would have nothing to play.

The car does not have the BA speakers. The powered sub does have its own amp and crossover. I have wired these in my previous cars before and have some other car audio experience. Since I am new to the Compass, I was just wondering where the best place to tap in for an audio signal would be. I was thinking the headunit. What is the easiest way to get to those wires? Do I have to disassemble the dash pieces from the top down or is there shortcut for those wires? That's really all I am asking. I have the navigation equipped headunit if that makes any difference. Would there already be wires set up to go to an amp or at least outlets on the unit for me to use?

Im not much help here, bacause I have the BA system, but on mine, without nav, and single CD, the deck has a digital output to the amp, and the amp does the signal processing duties, then spits it out to the speakers via analog signal. So you couldnt splice into the digital signal cable, youd have to do it after the amp. Problem is I dont know if the basic system is similar to the BA...I think they share head units though so its likely?

I can tell you where the BA amp is, and you could easily go see if you have one there too. Go to the rear hatch, and lift up the spare tire cover. Towards the front right of it, by the rear seat, under the carpet is the amp. If memory serves you can get to it just by lifting the carpet out of the way, or maybe it was plastic, either way thats where it is. Go see if you have one there, and what variety of wires go into and out of it.

About half way down on this page you'll find a couple of links. They may have what you're looking for meanwhile I'll check some other sources. http://www.jeepforum.com/forum/f98/q...5/#post6599929

Since the program for the wiring diagrams requires the obsolete IE6 browser the wiring diagrams won't open. You may want to call or go down to the dealer and they can print out the speaker wiring for you.
