Attention: TDR Forum Junkies 
I have the Infinity system in my truck, the one with the funky joy-stick for balance and front to rear. It's a really nice system except for the joy-stick MHO. The other day I noticed the left door speaker died. So I decided to install new speakers, what the heck they're only 12 years old :-laf
Anyway, upon removing the speaker to inspect if there was something that could be fixed, yankee enginuity . . . I noticed there was a "crossover" on the speaker. I wanted to diagnose the speaker to see if it or the crossover was bad. I was hopeful it wasn't the crossover, and hopeful I could purchase a replacement speaker or just the crossover if it was bad. I couldn't imagine what it would cost if I needed to purchase them as a set - which probably would have been the only option.
So, thankfully it turned out to be the speaker and not the crossover. I purchased some "direct replacement" speakers from Advance Auto. They had 2 choices listed one was a co-ax and the other was a tri-ax. Since I have the tweeters in the A-pillar I chose the co-ax. They were $47. 99 the tri-ax's were like $60.
So I get home to install them and realize I needed to figure out a way to incorporate the cross-overs and there wasn't any way to mount them on the new speakers. We'll I figured that one out and attached some pictures just in case someone else wanted to do the same.
Basically, I placed the cross-over on the speaker and thought about bonding it with poxy. Then I noticed there was enough meat on the thin metal speaker backing to drill
and screw the cross-over onto the speaker.
I placed the cross-over on the speaker, center punched (with a press to punch type tool) and with a super short drill bit 1/4" stuck out of the end of the drill (so as not to puncture the new speaker material as the bit went thru the metal) I drilled the holes. After mounting the cross-over and being rather pleased with the outcome I had to adapt the new speaker wires to the exisitng stock harness. No big deal, bare solderless butt connectors, heat shrink and re-tape the harness. Then I had to figure out how to attach the harness to the speaker, since the factory unit had a hole for a push in type wire harness holder. Simple, a small wire tie thru the hole where the wires plugged onto the spade connector on the new speaker.
Bingo, it worked like a charm. So well that now I'm thinking about taking a pair of old Pioneer TSX-120s that I've had in the garage for years, and still work very well, and placing them under the rear seat. I'm telling you these TSX-120s were "all that and a bag of chips" back in the day. I bought them back in 78 for like $100 +/- and had them in my Duster, then the Charger, then the F-150 and then the 4-runner. So, I figured why not? They still work fine. So that's my next thing to figure out, I'm guessing the rear door speakers dont have cross-overs as they're connected (most likely) to the ones on the front doors.
Check out the pictures. I'll update if I decide to install the TSX's in the back. Enjoy!
