Picked up a mint pair of SDA CRS +'s...I'd like to bring them back to their former glory, or better.

once I get those other crossovers I posted above, do I NOW have all the correct schematics below? If so, I'm going to try to learn how to read them properly.

1. stock


2. upgrade


3. the step by step process of doing the upgrade




are these all correct?

Do you have soldering supplies? If you have never soldered before, there is a bit of learning that should be done before you ever take an iron to the crossovers.

that's the one thing I actually do know how to do..haha...I'm not the best, but I have a fair amount of experience....I used to install remote starts/alarms/keyless entry and stuff like that in cars for a living..so i've soldered a TON of wires...and I've rebuilt a few modules for my Dodge Stealths/Mitsubishi 3000GT's over the last 20 years....I built a Dynaco ST70 and a Bottlehead Tube Amp....I recapped some things before...so I do know how to solder and desolder enough to get by...so far, the ECU that I recapped in my 1991 Stealth has been working since 2001...haha...

I just have no experience with working on the crossovers of these speakers...I've only ever did small stuff like replace tweeters and drivers, binding posts, dynamatting the baskets, etc...I never did any major work to their crossovers before...

The circuit diagram I marked up is ONLY applicable to modifying the 1986 version. If you acquire the newer pin/blade, single-board crossovers, then you should use the 4.1TL schematic as your reference to update to RD0198’s and 6510/6511 midwoofers. Forget the marked up diagram. It does not apply to the single-board crossovers.
