1-Get yourself and your tools ready (flat screwdriver, phillips screwdriver, 10mm socket wrench and extension, a couple of torx bits, dremel, drill, bits, etc.; lock your dog in her kennel with food and water so that she does not terrorize you while you are trying to concentrate; plenty of COFFEE).
Make certain we are in Park and the parking break is on for safety you know! Turn on some good music on the shop radio and sip some coffee.
2-I removed my passenger door and slid the passenger seat fully to the rear in full tilt to give me more room to work.
3-Remove those rubber cup holder liners in front of the console and in the rear. This should expose two bolts in the rear cupholder and one in the front.
4-Remove front bolt (10mm socket) and rear two bolts (torx 30).
5-Carefully work console out from under front tabs (plastic tabs will break so be careful) of shifter cover and work it out and ease it over into passenger seat (there is a wiring harness attached to it that we will remove next).
6-Unhook electrical harness by sliding red lock to the side and unplugging by pressing white tab. Study it for a minute so that you understand how it works without breaking it.
7-Once the harness is unhooked, the console should slide right out of the vehicle.
8-Take it to your workbench and empty the junk out of the top of it (old granola bars, pens, pencils, old insurance cards, and the pocket change).
9-Look inside console from the top and find two screws, remove them both, I think they are phillips head.
10-Flip console over and study how those shiny gold metal brackets are held in place by the plastic posts. There are two silver "star" washers pressed onto the posts holding tension on the brackets. They have to be CAREFULLY removed, or we will break the plastic posts. Sip some coffee here, and take a deep breath as you need a ton of patience here. Gently pry the tabs of the star washers back with a small flathead screwdriver and needlenose pliers to remove them. Don't force them or you WILL break those plastic posts.
11-Once the star washers are removed, flatten them back out as we have to reuse them; I just pinched them with my plilers to flatten them out again; set them to the side and take a deep breath. Almost there!
12-Lay the console on the side with speaker up, and remove the three screws holding the enclosure in place; these are phillips head as well.
13-Slide speaker/amp enclosure out of the center console. Get some cleaner and carefully clean out the inside of the console and the outside of the enclosure. My Jeep's previous owner had a major soda spill that was all over everything here...
14-Remove the old subwoofer by using a torx 15 bit; there are four torx screws holding it in. Also get a flathead screwdriver and pry it out because it is held in place with sticky tape. Do not damage wiring harness here! Once removed, examine factory subwoofer and marvel at the huge tear around the cone = BLOWN!
15-Look inside of enclosure and you will see some fins molded into the plastic just underneath where the speaker mounts; the central part has a semi circle "C" type look to it. These will have to be trimmed down some so that our new Pyramid will fit flush in the enclosure. Test fit new sub carefully to see this. Use caution with new sub as we don't want to damage its cone!
16-Carefully trim these fins down without cutting any wires. I used a dremel tool with a heavy duty cutting disc. Trim a small amount, clean it out with a shop vac, and test fit the new sub. Once it fits flush we are good!
17-Examine wiring harness and determine which wire is positive and which is negative; on my 2002 Jeep, the brown is positive, and the gray is negative. We will only use one set as we have a single coil sub as opposed to the factory unit's dual voice coil setup. This will change on certain year model's I am sure. A search on Google or a call to a local speaker shop may help you determine this. I had to solder a smaller connector on one of my wires to get it to fit snugly on the Pyramid, but that was no problem. I cut the connectors off of the unused wires and taped them with electrical tape to the main harness so there would be no shorts.
18-Once wired, check again to make sure you hooked it up properly, and test the unit by laying console in passenger seat and reconnecting harness to make sure it works. Be careful as the speaker is not fully mounted yet and you don't want to damage it!
19-Once we ensure it works, we need to mount it in the enclosure. Make sure the wires are routed with no interference, and lay your new sub in the enclosure. The mounting holes will not align so we need to drill new ones. Use a 3/32" bit (I think; compare it to the screws and make sure) to drill four new mounting holes using caution around the new sub; protect that sub with your hand as you don't want to run a drill bit through that cone!!!
20-Remove speaker and blow out any plastic debris.
21-Install speaker making sure wiring is connected properly, and routed properly; tighten four mounting screws (T15) only until snug. We are working in plastic and don't want to strip it out!! Be CAREFUL here!!
22-Sip more coffee and admire your pretty new speaker!
23-Reinstall enclosure into center console carefully while protecting speaker from damage. Reinstall star washers onto plastic posts; reinstall three screws on grille side of console; reinstall two screws in tray on top inside of console. Tighten only to snug, don't overtighten!
24-Reinstall center console into Jeep; remember to hook up harness and fasten red safety fastener on connector. Careful not to break any tabs here! Reinstall 10mm bolt in front cupholder, torx 30 bolts in rear (2) cupholder, and replace rubber cupholder liners.
25-Check your work and make sure no parts/fasteners are left out. Clean up tools and mess. Sip coffee.
26-Turn on radio and enjoy the no fuzzing blown speaker sound.
Again note that you are not installing an aftermarker amp with this unit so you are not driving it to its fullest potential with the factory mini amp, but it will sound 110% better than the blown factory unit, and we ARE on a budget with this project!!
Seriously, I hope this helps! Let me know how it works, and please ask any questions if you have them!
