Front speaker install on 2002 - replacing JBL speakers
This excellent writeup seems to be one of the only ones that still has pictures, so it was a great help for me yesterday while installing my new Infinity Reference 6030cs component speakers on my 2002 that had the stock JBL speakers. I'm updating this thread with a quick visual revision since the speaker stock mounting system seems to be slightly different than the earlier Hundy's, and this might help someone in the future by having the two installs in one place.
I replaced my front speakers only (so far) with Infinity Reference 6030cs component speakers. They are 6.5", 270w, 2-Ohm - pretty much a direct replacement for stock speakers on paper, and highly praised by the other Hundy owners who've also installed them. The only

challenge is that you have to wire up the crossovers and do some slight modifications to the mounting system, which was stupidly simple.
Step 1 is to get the door panels off - there's a pretty good writeup found
HERE. The only thing I had difficulty with is removing the trim plate behind the door lock mechanism. If you look carefully at the face of this part you'll see a black plastic "pin" between the lock and the trim piece - you need to get a flat screwdriver between this to unclip the top and bottom, then slide the trim piece toward the lock to unclip the little "J" clip behind the solid section. Do not try to pry between the trim and door panel, you'll most likely break something. After door panels are off, everything is accessible and is very simple to remove speaker parts.
I didn't take pics of everything, just the relevant items that are different.
Here I've already got the JBL speaker removed from the mounting bucket - simply unbolt the 4 mounting screws and used a sharp utility knife to cut through the rubberized gasket material to release the speaker. In this pic is the stock housing with the new speaker resting in place to determine mounting
the Infinity mounting diameter is slightly smaller than stock, and there are 2 plastic tabs preventing them from mounting flush. Tab removal and adapter plates will be necessary for correct speaker install

adapter plates underneath:

20 seconds with a small saw removes the tabs:
screw the adapter plates onto the housing (original screws in these holes were only 1/2", so pre-drilling was necessary to seat the replacement 1"+ screws the Infinity's come with). Then install the supplied gasket on the edge of the speaker. Lastly screw the speaker into the adapter plate which should already be installed on the housing:
Optional: solder stock speaker connections to the back of the speaker. Other option would be to put new connectors on the wires since the JBL setup has perpendicular connections vs the parallel ones on the Infinity's:
JBL tweeters were bolted to the mounting brackets instead of glued like the OP's rig had. I mounted my tweeters the same as the OP by using some heavy-duty foam tape (mine was servo tape for RC's - stuff holds like crazy!)
These last pics are where I chopped into the stock wiring to get my crossovers wired up. I did the optional connection method and soldered everything vs using crimp connectors. Used shrink tube to protect my connections vs tape. Tapped into the woofer wires to use as my inputs, but from research I guess either the tweeter or woofer wire could be used since the stock tweeters have capacitors on them - thus confirming the signal is the same for either set of wires.
Crossover location. Used 2 pieces of servo tape on the backs of crossovers for mounting
Before putting it all back together, make sure to test the system!!! I didn't and ended up having to take the panels back off. Problem for me was the soldering on the back of my driver's side tweeter grounding out on the tweeter mounting plate -- took me forever to figure that one out! If I'd do it over, I'd put liquid electrical tape over the solder joints on the tweeters before installing (wasn't my solder joint so I didn't even think about it when installing). Overall, I am VERY pleased with the new speakers. I put my crossovers on the +3db setting and I think it sounds much more crisp in the Cruiser. Very clean sound...now I just need to work on the back doors and the subwoofer
