Day 2 – the dashboard tweeters.
The new tweeters are JBL Club 750T units, and they came with an assortment of mounting brackets plus wiring harnesses. The wiring harnesses had some electronics covered in heat-shrink tubing right in the middle of the ~4-foot-long wire. I don’t know what’s there exactly, but I paid for it and the engineers obviously thought they are needed, so they were installed.
I was advised to get some backstraps to mount them, at $2 they hardly broke the bank but I’d later find out hot glue worked better.
But there was one kinda big problem – there were no wiring adapters for these speakers. I knew that when I bought the speakers so I had a few days to think of a solution.
After I removed the original tweeters, I found that I had, at most, 3 inches of wire to work with and the wire was anchored to something so I couldn’t pull any more out. Fortunately, it’s a socketed connection. Then there’s the fact that these are located at the base of the windshield. Cutting and soldering, or even (gasp) crimping just wasn’t going to happen here.
There is a way to deal with this, but it involves destroying the original speakers. No big loss there, so I cut the socket off of the old speakers and soldered my new wires to that socket! Problem solved!
Once the original speakers were removed, I had to determine which wire was positive. The original speakers are not marked, so my manual’s wiring diagram came to the rescue. By lining up the plug and socket, I could figure out which pin in the socket was positive and which was negative. I wrote that on the speaker magnet.
Bench time. I took the old and new speakers down to my sit-down bench in the basement, intended for electronics work like this. A soldering station, a lighted magnifying glass and related tools made this easy.
Pop the speaker out of the grille. Take a knife and scribe + and – on their respective sides of the plastic socket. Cut said socket off of the speaker, approximately at the blue line. A Dremel with a cut-off wheel works great here. Toss the capacitor (to the right of the socket here):
Then, solder your new wires on to the newly-liberated socket:
Mount the speaker inside the dashboard grille. These speakers came with a few different mounts and one happened to fit perfectly inside the round socket in the grille. A little hot glue and we’re done. Notice the big black thing of electronics on the wire. The finished product:
That ~4 feet of wire and the blob of electronics will fit in the space under the speaker in the dashboard. I just stuffed it all in there; maybe someday I’ll bother to properly tie off the wires somewhere.
Oh, how nice it is to be able to hear cymbal crashes, snare drums and other higher-pitched musical sounds with clarity. No more mush.
Doors are next, and I already know I will have problems there. Those new speakers don’t fit in the mounting brackets that are supposedly for this car. What I don’t yet know is, do the brackets fit the door?
