Installed the Pyramid today. Not as much bass output as stock (as expected), but better than it being blown.

I'm wondering the same thing. It looks like the Kicker 652 2 ohm has been discontinued, but you can still get the 651. I like the fact that the Kickers have more than 4 mounting holes...I figure 8 screws has to hold better than 4, especially since you are not going back in the OEM holes.

I don't know squat about car speekers...what difference does the ohm reading make?

Thanks.

"Ohms" refers to the electrical reisistance of a speaker. You should never use a speaker with less than the minimum ohms your amplifier or stereo is designed to handle. It's okay to go higher (it will just reduce the volume) but never lower. The lower the ohms, the lower the resistance - "0" ohms would be like shorting your "+" and "-" speaker wires together. A 2 ohm speaker doesn't offer much more resistance than that, and if an amplifier is not designed to handle that kind of current it will quickly burn it up.

Regarding the 8 vs. 4 holes comment. Not wanting to try to screw into flimsy plastic, I simply cut the frame off the factory speaker to use as a mounting ring. This way I was able to use the MUCH stronger factory holes. A little trimming of the plastic spacer ring and it looks like stock (I used the el cheapo speaker because I was selling that Jeep, but should work on any of similar size). See the picture of the finished product here:

Do you have a picture without the speaker cover on? Did you just "sandwich" the new speaker between the old mounting ring and the box?

Thanks.

So with the kicker 40cwrt671 the wiring is basically the same as stock 2 leads per coil?

No, but it wouldn't hurt.

I just did this on my 05. Mine had two extra mounting screws in the storage area of the compartment. Also nothing worked when I hooked up the gray and brown wires. Mine needed the red and black wires hooked up. Awsome write up though. I also found my pyramid sub woofer on eBay for $13.00 shipped.

Thank you, OP, for a great guide and pictures. I did this yesterday in my '04, it took about 45 minutes total.

As someone mentioned above, I also had two screws inside the console securing the enclosure from the top. The red and black wires were already connected to mine, with the grey and brown taped off, so I just used those. Worked like a charm.

CropDr, sorry for the delay - been away for a while.

I put thin weatherstripping foam on the back of the speaker flange to get good seal. Then I sandwiched the speaker between the trim ring I made from the old speaker and the box. Finally I used high strength double sided adhesive tape to attach the grill ring. I did have to trim the height of the grill ring so it wouldn't hit the cover. Hope this helps.

I just did mine the same way 58Willys did. Definatly the way to go....Sadly as I was tightening down the screws I sliped and put the screwdriver through the foam ring! I have some glew drying on it right now...hopefully I can save it!

I didn't bother with making the screen fit back over the speaker....I took some black felt and glued it to the inside of the arm rest housing. We will see how long it takes to fill with dust!
