If you haven't replaced a pair of from speakers in a Jeep Liberty with an Infinity sound system yet, then this tip may save you a little time in the future.

When you take off the door panels and remove the speakers, you will notice each front speaker will have a small amp attached to the bottom. Remove the amps from the speakers, they should just be mounted with a couple of screws. Disconnect the factory speaker, and extend the speaker wires, the Red wires are the positives and the Black wires are your negatives.

Unless you are adding a whole new aftermarket sound system and plan on eliminate the Infinity system, your going to want to keep these factory amps functional. The placement of these amps in the front doors when upgrading to aftermarket speakers is VERY IMPORTANT. If you do not move these amps to the right locations they will get in the way of the windows, and most likely damage the glass. You first want to move and place the amps on the out side of the window tracks, closest to the door jams.  

Make sure when you place the amps in the bottom corners, that the heat sink if facing the outside door skin.

This is what the heat sink side looks like, you don't want this side mounted up against the inside door panel. You want it facing the outside door skin inside the door panel. Otherwise, the amps will overheat.

The mounting holes for the amps are (1 11/16 In) apart.

With a Unibit/StepBit drill two holes on the left door panel (1 11/16 In) apart at about a 55 degree angle in the location I have market in the pictures on the left. Make sure the amp and all the wires are not in the way on the other side before drilling. On the right door panel drill two hole (1 11/16 In) apart at about a 135 degree angle in the location I have market in the pictures on the right.

The amps should then mount perfectly, with the harness coming off each factory amp facing up towards the door handle. Note: you will need new longer screws to mount the amps. After the amps are mounted, connect and mount the new speakers and that should be it. Like always feel free to comment or send me an Email if you have any questions.

  1. I installed a similar amplifier at the back of my car and it took quite some time before I finished it. Anyway, have you considered using brass screws instead of stainless steel ones? A friend of mine told me that he uses brass screws when he modifies his car because of its tensile strength. Still, there are advantages and disadvantages between these two materials. I'm just sharing my two cents.

    1. Hey, thanks for the comment! Yeah sometimes amp installations can be very time consuming. But it's always good to take your time and get everything dialed in just right. I have heard of using brass screws instead of stainless. It depends on the application, but can definitely be a better choice in certain cases.

  2. Do the screws go into tapped holes in the amp or do they require washers and nuts on the inside of door? If tapped, what is the size?

    1. I just completed this upgrade in my sons Jeep. to mount the amps on the inside of the door panels we actually got luck, as the thread is on speakers and not on the amp. So mounting them behind a panel would be difficulty with a long bolt and a small nut. I found some long bolts all OK, about 2 inches long, and the nut I used had a captive washer already attached (Captive nut). This nut fitted in the recess for the nut to go through, but best of all the spring washer actually gripped the inside wall of the hole, so it was like adding a threaded receiver into the amp, which when I located the amp behind the panel, allowed me to push the bolt through the door, then into the threaded hole in the amp. No worries about trying to get a nut on the back of the amp behind the panel. Real lucky but a great solution.
