Q: How to Upgrade Car Speakers, Including A-Pillar Tweeters on 2000 Dodge Ram 1500?
A: First cut the negative lead from the car's battery, remove the grab handle if you have one and unfasten the trim on the A-pillar before proceeding. Pull the trim off so you can remove the tweeter wire harness connector, disconnect it and remove the trim and tweeter together. Pull on the tweeter wire harness retainers at the back of the trim to unseat them from the heat stakes and then keep pushing the tweeter out until it comes free from the mounting hole. Separate the speaker wire from the negative battery cable. After removing the trim panel and detaching the four speaker screws inside the panel, pull out the speaker. Disconnect the wire harness and unplug it at the speaker's back. Before removing the rear cab side panel speaker, disconnect the car's negative battery cable, remove the trim around it and take out the two screws holding the speaker in place. Disconnect the body wire harness wire at the back of the speaker and then take out the speaker. Make sure the battery is off, remove the rear door trim panel and unscrew the two screws that attach the speaker to the inner part. Pull the speaker away so you can reach the wire connector on the door harness, take it out and remove the speaker. To install, put the A-pillar tweeter in the mounting hole, push it so it clicks into place, tape the wire harness and if you have grab handle and trim, reattach them before putting back the battery negative cable. For the front door speaker, fix it in place, plug in the wire harness, mount it to the hole, screw it in at a force of 4 Nm (35 in. lbs.), place the trim panel back and finally reconnect the negative battery cable. For the panel speaker behind the side of the rear cab, connect the harness, fit it into the mounting hole keeping the grille in place, tighten the mounting screws to 4 Nm (35 in. lbs.), install the trim and only then reattach the negative cable from the battery. For the rear door speaker, adjust its location, attach the wire harness, set it up in the mounting hole, screw it in to 4 Nm (35 in. lbs.), reattach the trim panel and lastly reconnect the negative terminal of the battery.
