2004 Jeep Liberty Front Speakers

[tormz]

I took out the stock Infinity System from my 2004 Jeep Liberty Limited this weekend. Got the 4 door speakers hooked up no problem.

The problem comes in trying to figure out how to hook up the front 3.5" speakers in the dash. What kind of crossover type box do I need to properly install these 3.5" speakers?

The stock set up had amps built into the front door speakers (those were removed). I replaced all the speakers with Kicker 6.5" with Polk sub/amp.

Just need to get the 3.5" hooked up for the full depth.

Thanks!
